Choose the correct statement

A

Haploid content of human DNA is 4.6`times` 10^(6)` bp

B

A nitrogenous base is linked to pentose sugar through phosphodiester linkage

C

X-ray diffraction data of maurice wilkins and Rosalind Franklin was the basis of watson and crick's DNA model

D

DNA is an acidic substance was first identified by waston and crick

Text Solution

Verified by Experts

The correct Answer is:
C

Among all the statements given about DNA only statement 'c' is correct while rest all others are not
These wrong statements can be corrected as Haploid content of DNA is `3.3xx10^(9)` bp
A nitrogenous base is linked to a pentose sugar through n-glycosidic linkage
DNA is an acidic substance and was first identified by Fraderick Meischer ltBrgt ratio between adenine thymine guanine cytosine are constant
