Question 1

What is a codon?

Answer 1

3 bases of RNA that will translate to one Amino Acid

Question 2

Are there aminos formed before the MET codon starts?

Answer 2

No

Question 2

Using the Codon chart, what does AUG code for?

Answer 2

MET, start codon

Question 3

What are the amino acids made used to make?

Answer 3

Proteins

Question 3

what is the role of mRNA, tRNA, and rRNA?

Answer 3

mRNA: Contains the message of code for amino acid sequences.
tRNA: Transfers amino acids, contains anticodons that pair with mRNA codons to put amino acids to synthesize proteins.
rRNA: Facilitate matching of mRNA and tRNA, joins amino acids to synthesize proteins.

Question 3

List the functions of the 3 sites; A, P, E

Answer 3

A (aminoacyl): Matches correct incoming tRNA to next codon onto tRNA
P (Peptide): Holds tRNA carrying growing polypetide chain
E (Exit): The place where anticodons exit

Question 4

What is a mutation?

Answer 4

CHange in the base sequence (order of A, T, G, C) molecules in DNA

Question 5

Silent mutations do what?

Answer 5

Change molecule without changing amino

Question 6

What are the point mutations?

Answer 6

Silent, Missense, Nonsense
