Hydrogen bonding base pairs

Postby Michelle Shin 4B » Sun Nov 10, 2019 5:25 pm

What is the difference between the AT and GC base pairs in the hydrogen bonding example used in lecture?

AT is held together by two hydrogen bonds, while GC is held together by three.

Since AT is held by two hydrogen bonds, these bonds are broken more easily. GC is held by three hydrogen bonds, so it is harder to break the bond between them.

Guanine and cytosine are held more tightly together than adenine and thymine in DNA because three hydrogen bonds link them as opposed to the two linking adenine and thymine.

AT and GC are the nucleotide base pairs that match up in the DNA structure. AT is held together by 2 hydrogen bonds while GC are held together by 3 hydrogen bonds.
