Question

During DNA replication, a DNA strand that has the bases CTAGGT produces a strand with what bases?

Answer 1

The new DNA strand will have the bases GATCCA.

Explanation:

Adenine (A) always pairs up with thymine (T), and guanine (G) will always pair up with cytosine (C).

(Adenine and Thymine have only two places to form hydrogen bonds, whereas Guanine and Cytosine have three places. Like goes with like, so..... )

You could remember it like this ~

Straight letters together, curvy letters together.

CTAGGT
GATCCA

So, that is why the new DNA strand will have the bases GATCCA.
