Question

3. DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine the sequence of the second strand

Answer 1

Yes, this statement is true. In DNA, the bases will always pair up in a certain way. If A (Adenine) is on one side, T (Thymine) will be on the other and vice versa. Similarly, G (Guanine) and C (Cytosine) also pair up like this.

Answer 2

Yeah, it is possible because we know that Adenine must bound to Thymine & Cytosine with Guanine. So, we can predict the alternative side easily.
