Answer:
wouldnt that lead to a variation of the trait?
Explanation:
DNA is a double helix. It is composed of sugar, phosphates, and four different bases: A, T, G, and C. As cells grow, DNA is uncoiled and used to make proteins, but sometimes DNA is different between two bees (or humans) and then different proteins are made. These changes in the order of the A, T, G, C bases can be mutations or natural variations.
Substitution: This is usually just one base that has changed in the sequence.
Addition (insertion): One (or more) base added to the sequence. The surrounding sequence is the same after the insertion ends.
Deletion: One (or more) base is removed. The surrounding sequence is the same after the deletion.
