I believe the answer is B
- In the mRNA; A will be complementary to U
- In tRNA; U will be complementary to A
The mutation does not affect the structure of the protein and is called a silent mutation.
<h3>What is a mutation?</h3>
A mutation is a change that occurs in the sequence of nucleotides of a gene.
The mutation that changes the base G in the DNA to A will result in the following corresponding changes in the mRNA and tRNA:
- In the mRNA; A will be complementary to U
- In tRNA; U will be complementary to A
The mutation does not result in any changes since the amino acid coded for by the mRNA has more than one codon coding for it.
This type of mutation is called a silent mutation.
In conclusion, some mutations occurring in genes have no effect on the proteins the gene codes for.

Unlike arteries, veins contain valves that ensure blood flows in only one direction. (Arteries don't require valves because pressure from the heart is so strong that blood is only able to flow in one direction.) Valves also help blood travel back to the heart against the force of gravity.
Primary producer, because it has to make it's own food.
