The codon chart below shows that adenine-uracil-guanine (AUG) codes for the amino acid methionine, and cytosine-adenine-guanine (CAG) codes for glutamine in humans.
What do those two codons code for in carrots?
A.
valine and aspartic acid
B.
isoleucine and histidine
C.
methionine and glutamine

serine and glutamic acid
The change of a UAC codon (Tyr) to a UAU codon (Tyr) is an example of a:
A.
missense mutation
B.
silent mutation
C.
frameshift mutation
D.
nonsense mutation
A missense mutation is a mutation in which:
a.
one nucleotide in a codon is changed, but the codon specifies the same amino acid
b.
a codon is deleted from a gene
C.
one nucleotide in a codon is changed, and the codon now specifies a different amino acid
d. one nucleotide in a codon is changed, and the codon is now a stop codon rather than specifying an amino acid
е.
a truncated protein is produced by translation
