Question

What are a few differences between DNA and RNA? Which is the one with two strands?

Answer 1

DNA is the one with two strands. RNA is the half of a DNA molecule.
I'll draw it :)

In DNA you have 4 types of nucleobases:
-C: cytosine (always links to guanine in DNA and RNA)
-G: guanine (always links to cytosine in DNA and RNA)
-T: thymine (always links to adenine in DNA)
-A: adenine (alwyas links to thymine in DNA)

In RNA you have the same nucleobase exept the T (thymine) is replaced by U (uracil)
Uracil links to adenine just like T does.

When 2 nucleobases are linked in DNA, you call them basepairs

So RNA is like a DNA template, since only specific nucleobases can link the nucleobase that are on the RNA molecule, the other half is already known.

I added an image of RNA and DNA in the attachement.

Answer 2

Thanks soo much! :)

Answer 3

RNA is a singled strand and DNA is a doubled helix
