What does 3 prime end and 5 prime end mean in dna and rna? so dna and rna are nucleic acids.
00:08
They're made up of nucleotides.
00:10
So i'm going to draw one nucleotide, and i'm going to draw a second nucleotide.
00:23
Okay.
00:25
So the parts of a nucleotide, these are the base pair, the bases, adenine, guanine, cytosine, thyminal uricil.
00:33
These are the phosphate groups, and these are the...
00:42
The sugars.
00:44
Ribose or deoxyribose.
00:48
When two nucleotides are connected in a chain, like in dna or rna, the bond is between here and here.
00:57
And then this has an open hydroxyl group, and that's where this bond comes from.
01:03
So if we close up on this bond, we have the phosphate group, and we have this hydroxyl group.
01:18
And when they bind to each other.
01:20
What happens is we lose these and we get a bond here...
