The total number of hydrogen bonds of a DNA-double Helix strand whose one strand has the following sequence of bases is .
5' - G-G-C-A-A-A-T-C-G-G-C-T-A-3'

Question

Canvas Classes · Accepted Answer

In a DNA double helix, the two complementary strands are held together by hydrogen bonds between specific pairs of bases:
- Adenine (A) pairs with Thymine (T) via 2 hydrogen bonds.
- Guanine (G) pairs with Cytosine (C) via 3 hydrogen bonds.

Let's count the bases in the given sequence: 5' - G-G-C-A-A-A-T-C-G-G-C-T-A-3'
- Number of G-C (or C-G) pairs = 
Wait, let's look at the exact given sequence:
G (1), G (2), C (3), A (4), A (5), A (6), T (7), C (8), G (9), G (10), C (11), T (12), A (13).
