DNA and RNA word list due Wednesday 10/26/11
WORD LIST- for DNA
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. Polypeptide bond- it’s what connects one amino acid to another to make a complete protein.
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!

energy reactions re-teach information
I absolutely love this web page- read it all , click on everything, submerge yourself in the energy cycle we are all swimming through- at least until that lactic acid makes us sink!!!!
http://www.ftexploring.com/me/photosyn1.html
here's more:
Bioenergetic reactions help
Here's an overview of photosynthesis:
click on the "illuminating photosynthesis" link and then go through all 3 tabs at the top.
http://www.pbs.org/wgbh/nova/methuselah/photosynthesis.html
then go here for a start to finish explanation of how this all works:

Window pane terms for this week- due thursday10-20-11
1. ATP- Adenosine triphosphate- this is your cell's basic unit of chemical energy made from breaking down a glucose molecule.
2. Lysis- to split something open- in biology it is usually water breaking things down.
3.synthesis- " to make" something, you are building something, usually a compound in your body.
4.Activation energy- least amount of energy required to start a chemical reaction ( happens at the arrow in an equation, it's 2 ATP for Cellular respiration).
5.aerobic- a reaction that is using oxygen.
6. anaerobic- a reaction that is not using oxygen.
7. fermentation- a type of bioenergetic reaction that occurs in plants and animals when oxygen is not available- a back-up energy process, there are two types you need to know; lactic acid fermentation (animals and certain bacteria) and alcohol fermentation ( plants and certain bacteria).
8.Respiration- the process of taking in essential materials for life and releasing waste products.
9.photosynthesis- the process of taking in solar energy and converting it to chemical energy.
10. metabolism- an organisms ability to use and transform matter to run life processes.

Bioenergetic reactions starts Monday!
Bioenergetic reactions= break the words down!= chemical reactions that produce energy and occur inside of living things.
This interactive takes a fun look at photosynthesis!
http://www.pbs.org/wgbh/nova/nature/photosynthesis.html
We will also cover aerobic ( with oxygen) respiration and anaerobic respiration ( with out oxygen). alcohol fermentation and lactic acid fermentation are two types of anaerobic respiration.
This is how sugar (glucose) gets turned into ATP inside your cells:
If you add them up, you'll see that 38 ATP are actually made, but two are used in the process so we say that a net total of 36 ATP are produced!

Things we need for hot cocoa fridays!!!
OK everyone, time to start one of my favorite fall traditions! There's a nip in the air (at least in the morning!) which means it's time for Hot Cocoa Fridays!
This means I need some help stocking up on supplies :)
1. We will need cups for hot substances- the paper kind- No STYROFOAM PLEASE BECAUSE IT'S REALLY, REALLY BAD FOR THE ENVIRONMENT.
2. mini-marshmallows
3. OUR CLASSROOM COULD ALSO BENEFIT FROM SOME SMALL PENCIL SHARPENERS FOR WHEN WE USE THE COLORED PENCILS OR HAVE TO USE A SCANTRON.
It's been a good 6 weeks, the next 6 will be harder but we'll make the best of it!
Enjoy your weekend; go play in some leaves and enjoy all of the wonderful Abiotic and Biotic factors around you!
