Hello everyone.
00:01
So this question is about nitrogenous basis of nucleotide.
00:05
So first we will see what a nucleotide is.
00:08
So a new nucleotide is basically composed of three things.
00:16
A nitrogenous base, a pentose sugar and a phosphate too.
00:22
So this pentose sugar, this can be of two types.
00:27
It can be deoxyribose sugar or ribose sugar depending on the fact if it is present in the dna of our body or the rna, respectively.
00:43
Now talking about the nitrogenous basis of a body, they can be classified into two, namely purines and pyrimidians.
00:55
Now the purines, they comparates of adenine represented by a and 1e represented by g.
01:02
The pyramidine comprise of cytosine, represents, represented by c and thymine represented by t.
01:08
So this is the composition when the nucleotide bases are present in the dna.
01:14
But if they are present in the rna, so there is another pyramid called as urescent represented by u that replaces the thymine in the rna.
01:26
So these dna or rna, they can be single stranded or they can be double strand...
