Protein synthesis tutoring and re-takes

If you didn't do so hot on the protein synthesis  test please stay during lunch or come by after school for tutoring. You have until the Thursday of next week to re-take the test. 
If you come for tutoring I will allow you to score higher than the standard re-take grade.

If you CAN'T make it to tutoring but you know you need help please use Kahn!

Kahn - overview of replication, transcription and translation

Kahn - translation process

We are moving on to heredity now so I'll go ahead and attach the latest word list, it's a doozy, so don't put it off to the last minute. They are due next week, Tuesday, 11-14-17

Heredity word list: 24 terms

protein synthesis test tomorrow

Hey, we'll have about 30 minutes tomorrow to review before I give you the test. Work on your cartoon/ analogy tonight and we'll read some off tomorrow to make sure we know what's going on before I give you the test.

Here's a copy of the paragraph we started in class today: (I've done a bit of editing)

First the cell receives a signal that something is needed. mRNA responds by going to the nucleus to find the gene that codes for the needed protein (remember a protein can be an enzyme, hormone or other type of tissue).Transcription happens next, this is when  mRNA writes down the gene using complimentary RNA bases. When finished mRNA finds a ribosome and enters it 3 nitrogen bases at a time (one codon at a time). The ribosome reads the codons and then calls out for the corresponding  amino acids needed. tRNA hears the call and  then brings the  appropriate amino acid back to the ribosome ( it double checks where to drop it by matching codon with anti- codon) The amino acids are then attached together using  strong peptide bonds. Translation (going from mRNA to amino acids) is now complete. The chain of amino acids is then released and folds into a specific protein shape.

Here's the sample key we made up in class:
Characters                    DNA equivalents
safe=                                                             nucleus
instructions=                                                 DNA
spy=                                                              mRNA
copying instructions=                                  transcription
factory=                                                        ribosome
name of each supply (purple fabric)=          codon
actual supplies (a pile of purple fabric=      amino acids
employees that bring the supplies=              tRNA
going from instructions to shoe=                 translation
stitching, velcro or glue =                             peptide bond
sneaker=                                                       Protein
