Okay, in order to show this question we have to talk about the structure and the functions of dna versus rna.
00:14
So, first, remember that both are polymers of nucleotides.
00:25
Both are made practically of nucleotides.
00:29
And what are nucleotides? well, first, remember that you have nitrogenose basis, okay? nitrogenous bases that can be a from adenine g from one in c from cytosine and t from thymine okay the difference is that dna is going to have timing as a nitrogen base and all the others but in case of rna it is going to have uracine instead of instead of timing okay and all the others too so a nucleotide is going to be made of a nitrogen of base plus a pentose sugar plus a phosphate okay but remember that in dna you're going to have thymein and in the in rna you're going to have uracine so one difference between them is that dna is going to have thymin while rna is going to have uracine that's the first difference okay also another difference is that the sugar pintoose sugar in dna is going to be deoxy guibose while in rna it is going to be guy those are the difference until now now another difference is that dna is usually double stranded it means it has two strands okay while rna is generally single stranded, single stranded.
02:17
Okay, it means it only has one strand.
02:20
And finally, dna is going to, particularly dna stores all the information, all the genetic information, okay, of an organism, okay, of the organism and it is going to be transferred to $2 ,000 cells when dna replication occurs...
