Hello, so let's answer now the question.
00:03
So in this question, we have four segments of different dna, and each segment is a double helix dna.
00:12
Now, here we are asked which of this segment would need the most energy, okay, would need the most energy for the separation of the two strands.
00:35
Now take note that if the strand has more hydrogen bonds, then it will need more energy.
01:07
It will need more energy to separate.
01:15
Now, the hydrogen bonds between a and t is two hydrogen bonds.
01:23
The hydrogen bonds between c and g are three hydrogen bonds.
01:36
Therefore, if there are more cg or cytosine -guanine -based pair in the segment, then that segment of dna will need more energy to separate, since again there are more hydrogen bonds in the segment...
