A segment of DNA has the following nitrogen base sequence: ACT TCG. (Please answer both)

A. What base sequence would appear on the complementary strand?

B. Using the above nitrogen base sequence, give a possible sequence showing that an error has occurred in the second base.​

B is the correct answer

Explanation:

using th above nitrogen base

Explanation:

adenine (A), thymine (T), guanine (G) and cytosine (C). These nucleotides come together to form long chains known as DNA strands. Two complementary DNA strands bond to each other in what looks like a ladder before winding into the double helix form.
