The question is all our differences between dna and rna except, so we have to tell out of all these five options which one is not a difference between dna and rna.
00:12
So let us first understand.
00:14
Dna stands for deoxyribonuclic acid, whereas rna stands for ribonuclic acid.
00:30
Dna is a double -stranded molecule.
00:33
So dna, we can see dna has a double strand whereas ribonuclic acid is single -stranded.
00:43
In dna, in dna the adenine base pair, it pairs with thymine, whereas in ribonucleic acid that is rna, adenine forms two hydrogen bonds with urea.
01:03
Coming to the sugars, so deoxyribonucleic acid that is dna, it has deoxyribose sugar, deoxyribose sugar, whereas rna has ribose sugar.
01:23
Okay, so these are the differences between dna and rna.
01:28
Now let us see all the points.
01:30
The first point says dna double strand, rna single strand, as a single strand.
01:34
As we have seen, dna is formed by two strands whereas rna that is ribonuclic acid is formed by one strand.
01:43
So option a is correct.
01:45
Option b, dna use thymine whereas rna use uresil...
