Do you know what nucleotides and hydrogen bonds are?

OpenStudy (cal.lavender):

Yes, do you know what are nucleotides and hydrogen bonds?

OpenStudy (inkyvoyd):

Describe them briefly?>

OpenStudy (cal.lavender):

ok, than firstly you need to know that DNA is a group of nucleotides that are linked together

OpenStudy (cal.lavender):

The two strands of DNA are linked and stays in a stable shape because of the hydrogen bonds located between adenosine and thymine base pairs. Three hydrogen bonds are between cytosine and guanine.

OpenStudy (cal.lavender):

@studen9 can you tell me what is adenine only?

OpenStudy (cal.lavender):

And thymine?

OpenStudy (cal.lavender):

What do you think, if adenine is related to DNA, can thymine too be related to DNA?

OpenStudy (cal.lavender):

Than make up the definition, just like adenine

OpenStudy (cal.lavender):

yes, correct, now make up the definition

OpenStudy (cal.lavender):

Thymine is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The others are adenine, guanine, and cytosine.

OpenStudy (cal.lavender):

Try and think, what's common between the two?

OpenStudy (cal.lavender):

They would be the same, because one side of the DNA would have adenine and the other thymine in the same place, and they can only link to each other. Same with guanine and cytosine, but in RNA uracil replaces thymine.
