Question

If a DNA strand has a nucleotide base sequence

of A-T-T-A-C-G-C-A-T, what will the sequence

of its complementary strand be?

Answer 1

T-A-A-G-C-G-T-A would be the sequence of it's complementary strand.

Step-by-step explanation:

This is because there are 4 nucleotide bases which math with only a certain other nucleotide, which are

• A as in Adenine matches with T as in Thymine.

• T as in Thymine matches with A as in Adenine.

• C as in Cytosine matches with G as in Guanine.

• G as in Guanine matches with C and in Cytosine.

A good way to remember this is, the letters that are only made of nothing but straight lines (A, T), match with each other, and the letters that have curves in them (C, G), watch with each other.

Hope this helps!
