Hello everyone so let's start this video the question we have over here is all of the following about the structure of dna are correct except dna is a polymer dna contains deoxy ribose an an an an anucleids to go on in the nucleotides consist of sugar phosphate and nitrogenous base so the first statement that dna is a polymer this is correct this is true and the second dna contains deoxyribose sugar, this is also correct.
00:39
And denuclite consists of sugar, phosphate and nitrogenous base.
00:43
This is also correct.
00:45
See, erinine modes to gonium.
00:49
Well, erronein and gonin, these are nitogeneous bases.
00:55
Dna has four nitrogenous bases, nitogeneous bases.
01:10
And these bases are...
01:14
Ironine, guan, cytosine, and thymine.
01:31
And rna also has four nitrogen bases...
