A codon, which codes for 1 amino acid, consists of how many bases?

• 1

• 2

• 3

• 4

Use the wheel to find what amino acid is created by a GGG codon.

Sometimes a single amino acid can be coded for by multiple codons. How many different codons code for the amino acid leucine? (Trick question)

• 2

• 4

• 6

• 8

From a gene found in a DNA strand you are given the bases of ATG. Using transcription rules, find the amino acid that would be coded for from the resulting mRNA. Use the codon wheel to help.

• Leucine

• Isoleucine

• STOP

• Tyrosine
