Use your decoder ring to translate the following mRNA sequence

AUG CCG UAG

Methionine (start), Proline, STOP

Use the following DNA sequence to get a sequence of amino acids:

TCG ATT TAT

Serine, STOP, IsoleucineYou must TRANSCRIBE to mRNA first, then

TRANSLATE into amino acids.

A tRNA molecule is carrying the amino acid TRYPTOPHAN. What ANTICODON does the tRNA moelecule have?

ACC

Describe the relationship between a gene and a protein.

A gene is a segment of DNA that can be transcribed into mRNA to be translated into a single protein.
