00:01 In this question we are given some of the terms.

00:03 So these are the terms that we are given and we have to match them with their proper description.

00:10 So the part a is asking which one out of these following could contain the nitrogenous base thymine? okay.

00:19 So for that, let us see dna as well as rna.

00:26 So dna we know it is deoxyribo nucleic acid whereas rna is rna is.

00:31 Ribonuclic acid.

00:35 So the nitrogenous bases which are present in dna are adenine, thymein, guanine as well as cytocene whereas the nitrogenous basis present in ribonucleic acid are adenine and instead of thymine we have uracil the rest nitrogenous bases are same that is guanine and cytosine.

01:04 So here adenine forms two hydrogen bonds with thymine whereas guanine forms three hydrogen bonds with cytosine.

01:12 But in the case of rna, adenine forms two hydrogen bonds with uracil whereas guanine, it forms three hydrogen bonds with cytosine.

01:24 So we can see that the difference of nitrogenous base, which is thymine and uracil.

01:32 So the nitrogen is based, thymine can be present in dna, that is deoxycinous base.

01:38 Ribo -nucleic acid.

01:40 So our one term is done.

01:43 Next that we have is the monomers of nucleic acid.

01:46 So we know that nucleic acid is made up of nucleotides and these nucleotides are further made up of three components which is a five carbon sugar, nitrogenous basis and phosphate.

02:06 So these are the three components that make up nucleotides and the nucleotides further form nucleic acid.

02:15 So the monomers of nucleic acids are nucleotides.

02:21 So we are done with nucleotides also...
