DNA and Protein Synthesis Review

The RNA codon AUG means

• add amino acid methionine

• start the protein here

• add the amino acid tyrosine

• end the polypeptide chain here

The main function of tRNA is to...

• carry a message that, when translated, forms proteins

• form a portion of ribosomes

• string together complementary RNA and DNA strands

• bring amino acids from the cytoplasm to the ribosomes

Insertion, deletion, and substitution are all examples of a change in a genetic sequence which is also referred to as (a)

• Gene

• Amino Acid

• Ribose

• Mutation
