Question

1. if i change 1 base from an a to a g how would that change affect the complementary base strand?

1. what do you notice about the left strand of nucleotides vs the right strand?

Explanation:

Question 6

In DNA base pairing, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). If an A is changed to a G in one strand, the complementary strand's base that paired with A (which was T) will now need to pair with G. Since G pairs with C, the complementary base will change from T to C.

In a DNA double helix, the two strands of nucleotides are complementary and antiparallel. Complementary means that the bases on one strand pair with specific bases on the other (A - T, G - C). Antiparallel means the strands run in opposite directions (one in 5' - 3' direction and the other in 3' - 5' direction). Also, the sequence of one strand can be used to determine the sequence of the other due to base - pairing rules.

Answer:

The complementary base that originally paired with A (thymine, T) will now pair with G, so it will change from T to cytosine (C).
