Tadpoles LOVE cooked lettuce!

Hungry, hungry, tadpoles! They were swimming all over the place, then the minute I put the cooked lettuce in the container they zoomed in on it and started munching. Yay!

Biology RE-test on Protein synthesis will be Tuesday or Wednesday review links posted

Hey, if you are still having trouble with protein synthesis, don't be too hard on yourself! It's tricky. Go to these sites and watch them go through it a time or two and see if that clears anything up for you.

REMEMBER :  Before any of this starts mRNA gets a chemical message that your body needs something (insulin for example). transcription occurs next: mRNA then enters the nucleus to read and write down (in mRNA letters) the information on  the gene that codes for the needed protein (insulin) . The part where the mRNA is read by the ribosome and amino acids are brought back to the ribosome is translation


Next word list:

Window panes due Thursday 4-2-15 .THEY WILL NOT BE ACCEPTED LATE!

1.ALLELE- a segment of your DNA (or gene)that codes for a trait in your body. You have two alleles for every trait in your body (with one exception- naturally!).

2. Homozygous alleles- this is what we call the genetic situation when both parents give the same information (genes) for a trait. For example: both of your parents give you the gene for blonde hair, you have no other choice than to have blonde hair.

3. Heterozygous alleles- this is what we call the genetic situation when your parents give you two different genes for a trait. For example: Your Mom gives you the gene for brown hair and your dad gives you the gene for blonde hair- now your Genome has to decide which proteins to make- ones for brown hair OR ones for blonde hair- who will win? read on to find out!

4. Dominant traits (or alleles or genes)- This is when one of the alleles from a parent is stronger than the allele from the other parent so it's the one you use and, therefore,it's the trait that you have. Brown hair is dominant to blonde hair, therefore, you will have brown hair and you won't even know that you have a secret hidden gene from your other parent! (you can probably figure it out though- either by what your parents look like or what your kids look like) We only use one letter to represent a trait when we are trying to predict what traits a person will have, the Dominant trait determines what the letter will be and it (dominant one) will be uppercase- the recessive trait will use the same letter as the dominant trait, but we show that it is recessive by making it lower case!

5.Recessive traits (or alleles or genes)- This is when one of the alleles you get from a parent is weaker than another. You don't use this gene because you favor the stronger gene. In this way it is a hidden, secret gene, that you may never know you have. Even though you don't use this gene in your body, you do have the potential to give this "recessive" gene to your children and (depending on how the shuffling goes during meiosis) they could end up having that recessive trait. EVER see two brown headed people with a blonde baby- their baby- they both had a recessive allele for blonde hair!!!!!!

6. Co-dominant alleles- this is when you have heterozygous alleles for a trait (that's two different alleles) and they are equally strong so they both show up!! This is how you get stripes and spots in fur- neat,hugh?

7. Incompletely dominant alleles- this is when you have heterozygous alleles for a trait (that's two different alleles) and they are equally strong, so they duke it out and decide to compromise- they meet in the middle- you no longer see the original traits but a medium version of each trait- think Pink! As in: Red mixed with White makes PINK!

8. Genotype- this is how we refer to the "letters" or alleles you carry- you always have two- one from mom and one from dad. TT or Tt where "T" is tall (dominant) and "t" is short (recessive).

9. Phenotype- this his how we refer to the visible PHYSICAL features that result from your alleles - "Tall" or "Short". It's what we see and know you have with and/or without knowing what your DNA says.

10.Gregor Mendel- a Monk/ gardener that figured out "genetics" using pea plants. He just cross pollinated pea plants that had different colored flowers and figured out the whole dominant/ recessive trait thing. Genetics that deals with only dominant and recessive traits is even called "MENDELIAN GENETICS".

11. HYBRID- this is how we sometimes refer to the crossing (or breeding) of two different different organisms of the same species. YOU are a hybrid of your parents!!! when we are crossing to test one trait it's refered to as a monohybrid cross ( two traits would be a dihybrid cross)

12. Purebred- This is the same thing as being homozygous, ( you could be homozygous dominant TT or Homozygous recessive tt and still be considered "purebred")

13.X-linked or sex linked- This refers to traits found on the last pair of chromosomes ( the ones that determine whether you are a girl or a boy). Males only have to have one recessive allele for a trait to show up if it happens to fall in this area (most common x-linked traits are; colorblindness, hemophilia and balding)

14. carrier- This is how we refer to a person who is Heterozygous for a trait, they have a recessive allele for something that they will never get, but they can give that allele to their children who may possibly get the trait. ( Mom of cystic fibrosis child is not sick, but child is because she and her husband were carriers of the trait).

15. Pedigree- a chart that shows who of your ancestors carries a trait. circles are girls, squares are guys and shaded shapes have the trait being charted. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiX56bRVBks0jhnCcpe51oCCa2pBgI__vKsQPDaYYojK67uG2Z0i3nDGCZmmFTzxWvsjGsDaNlxgmAzxiTnMEY291ydSlFu6kxOmjfps8wFhQXucVovWJrZN5KdZHf1RhHA0ujLXCrbpZgN/s1600/ftree.gif

16. Karyotype- a picture that shows paired chromosomes- can use it to determine the sex of a person or to check for Down's syndrome or any other trisomy ( 3 chromosomes instead of 2).

17.Intermediate inheritance- another term to describe a trait as being a result of co-dominant alleles or incompletey dominant alleles.

18. Polygenic- when more than one gene contributes to a trait- skin color is a result of the interaction between 7 different genes (which means 14 different alleles!), eye color is the result of 3 different genes.

19. Autosomal inheritance (or autosome)- when an allele is found on any of the 22 chromosomes that don't determine sex, so chromosomes 1 through 22 are autosomes. chromosome 23 is a sex chromosome.

20. Huntington's disease- is a disorder passed down through families in which nerve cells in certain parts of the brain waste away, or degenerate. It is an autosomal dominant disorder located on chromosome 4.

BIOLOGY protein synthesis word list: window panes due on Monday ( 3-23-15)

1. Complementary base pairs- The nucleotides that fit together to form the DNA double helix, adenine with thymine and cytosine with guanine .
Here is a visual, if the original strand of DNA has the following bases:    A T C G A T T C G A T (ORIGINAL OR TEMPLATE)Then the complimentary bases would be: T A G C T A A G C T A (COMPLIMENT TO THE ORIGINAL)

2. Replication- the process of copying the original strand of DNA to form a new, IDENTICAL, strand of DNA so that when the cell divides the daughter cells have the same exact genetic information as the parent cell.

3. Mutation- any change in someone’s strand of DNA, it could be a few letters (bases) or just one base.

4. Protein synthesis- using a cells DNA to code for and then make a specific protein needed by the cell, three types of RNA are needed to do this.

5. Trait- a physical characteristic or feature of a person (ex; brown hair, tall, diabetic, blue eyes)

6. Genes- the segments of a person’s DNA that code for a certain trait.

7. Transcription- when mRNA copies a segment of DNA in order to take the message out of the nucleus and to a ribosome. It must be written in the RNA’s language which uses Uracil in place of thymine for a nitrogen base. The uracil still pairs up with Adenine.

8. mRNA- messenger RNA is the RNA responsible for sneaking into the nucleus of a cell and copying off a certain piece of DNA and then carrying that piece of the code out to a ribosome.

9. Codon- three letters of a mRNA strand that determine which amino acid is to be made by a ribosome.

10. Translation- when the code made by the mRNA gets turned into an amino acid in a ribosome.

11. rRNA- is ribosomal RNA, it’s what makes up the ribosome and turns a mRNA codon strand into an amino acid strand.

12. tRNA- is the type of RNA that puts all of the amino acids in the correct order to form the proper protein. It has a complimentary RNA code for the newly produced amino acid to hook on to.

13. Peptide bond- it’s what connects one amino acid to another to make a complete protein. a long chain of these amino acids can be refered to as either a protein or a polypeptide.

14. Hydrogen bond- weak bond that holds nitrogen bases (A with T or C with G) together. 

15. Anti-codon- located at the bottom of the tRNA , it has the opposite nitrogen bases of the codon and its purpose is to make sure that the amino acids are returned to the proper place on the mRNA strand being translated at the ribosome! This insures that the codons are put in the correct order, regardless of who gets back to the ribosome first.

APES this week (3-16-15 to 3-20-15)

This week we will be doing or setting up a lab every day! Make sure you are on time and present or your lab write-ups will be very difficult, it is not possible to re-do labs with you after school.

Have your lab notebooks daily

You will complete a population study guide on your own at  home. It follows directly along with the "Habitable Planet" site.  It is due on Thursday 3-19 and your test will be Friday.  If you want to use a mind map it too must be completed by Thursday. 

I will handout the study guide in class tomorrow.

http://www.learner.org/courses/envsci/unit/text.php?unit=5&secNum=0


Remember: if you are absent for any reason, it is your responsibility to obtain your work as soon as possible. You must come to see me for handouts and obtain missed notes from a peer. I will not be emailing any copies of material.

Study guides:
I expect you to read everything on the page and 
to complete your study guide independently. Taking shortcuts hurts your grade because you don't fully understand the dynamic you are studying. Also, copying someone else's work is cheating and will result in a zero.
