Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic acid or DNA ... chemical bonds called hydrogen bonds.

Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between ... strand, DNA polymerase wraps itself around that strand, and it attaches new nucleotides to the exposed ...

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...

The thymine-adenine (T-A) base pair is held together by fewer hydrogen bonds compared to the guanine ... DNA polymerase enzymes use the existing DNA strand as a template and add the complementary ...

It's not hydrogen bonds don't have a role to play. They're still the ones responsible for sorting base pairs and making sure they're all in the right sequence. But, it's water that holding the DNA ...

RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note - RNA ...

The remaining positions are occupied by carbon atoms, forming the backbone of important nucleobases in DNA and RNA. (Image ... The ability of pyrimidines to form hydrogen bonds and engage in π-π ...
