The question wants us to find the exception among the other four true statements about dna.
00:07
Now here the key word is the term except because we have to find the wrong statement.
00:14
And the short forms atgc stand for adinine, thymine, guanin and cytosin, which are the nitrogenous spaces found in dna.
00:22
These are the standard short forms that are used in biology.
00:27
Now we'll be approaching this question from a theoretical aspect, learning.
00:32
All the different options together.
00:37
Now looking at the structure of the dna, which is deoxyribonucleic acid, we can say that it's a double helic structure and it has two anti -parallel strands because one strand is 3 -5 to 5 -prime, another strand is 5 -2 -3 -prime.
00:52
And what's a nucleotide? it's basically a sugar plus phosphate plus nitrogenous base, where the sugar is deoxyribos in the case of dna.
01:04
That's why its full form is deoxyribunuclic acid and hence it is a polymer of nucleotide.
01:12
Now the sugar plus phosphate together make up the backbone of the dna.
01:18
Now if we enlarge a section of the dna we will get two antiparallel strands which have the nitrogenous bases atgc, atgc all in the complementary base pairing with adenine binding to thymine and guanin binding to cytosin always...
