- what is the significance of famous dna structure experiment?Choose all of the statements that correctly describe the base pairs drawn below. A C H H-N -H-N N-H- -N B H D موعة Rita N -H---- 2 NHN O- -H-N H -H- N- -H-N The non-Watson-Crick base pair shown in A is much less stable than the base pairs shown in B and C, because the smaller size of the two pyrimidine bases induces a distortion in the structure of the double helix that decreases the stability of the helix when compared to helices with the normal Watson-Crick base pairs. The base pair shown in B is found in BOTH DNA and RNA The base pair shown in C is found ONLY in RNA and NOT DNA The base pair seen in B is more stable than the Watson-Crick base pair shown in C partly because of a larger number of hydrogen bonds and partly because of more favourable pi-stacking interactions with adjacent base pairs.If a double stranded DNA HAS 20 PERCENT OF CYTOSINE, calculate the percent of adenine of adenine in the DNA?
