So the question we have is one species dna differs from others in its dash, right? so nucleotides, dna sequence, double helix, sugar phosphate backbone, right? so, you know, deoxyribose nucleic acid, which is the dna, is a polymer, right? it's a polymer made up of nucleotide monomers.
00:34
The composition of a nitrogen base of sugar and the phosphate refers to nucleotide.
00:43
The nitrogen and nitrogen bases includes adenine, coanine, cytosine, thymine.
00:53
Those nitrogen bases, sugar phosphate backbone in the dna structure, and the dna structure, and are common for all the species, but the sequence of the nucleotide are not common for all the species.
01:09
According to the irvin shagov's identification about the nucleotides, the proportion of adenine and goanine differs in different species, which gives the clue that nucleotides are sugar backbone are common to all the species, but the difference.
01:30
Caused due to the sequential arrangement of nucleotides so therefore the options a c and d these three options are not the correct answer right dna is the genetic material which contains all the hereditary information based on the sequence of nucleotide arrangement the order of arrangements of the nucleotides varies in every species...
