Question
Which of the following pieces of DNA is going to be easier to separate into single stranded molecules using heat (ie, have a lower melting point), which breaks hydrogen bonds? Why?
1. 5’ ATTTTCCGTAAT 3’
3’ TAAAAGGCATTA 5’
2. 5’ ACGGTTTACCGG 3’
3’ TGCCAAATGGCC 5’
A) 2; it has more C-G pairs which are connected by three hydrogen bonds instead of two, so they are easier to break.
B) 1; it has more A-T pairs which are connected by one hydrogen bond instead of two, so they are easier to break.
C) 2; it has more C-G pairs which are connected by two hydrogen bonds instead of three, so they are easier to break.
D)1; it has more A-T pairs which are connected by two hydrogen bonds instead of three, so they are easier to break.
