Which of the following statement/s regarding nucleic acids is/are wrong? I. Haploid content of human DNA is 3.3 xx 10^(9) bp . II. RNA is the genetic material for the majority of organisms. III. Both RNA and DNA can function as genetic material. IV. The bases in two strands of DNA are paired through disulphide bonds forming base pairs (bp). (V) In RNA, every nucleotide residue has an additional -OH group present at 2'-position in the ribose.

Read the following statements and find out the incorrect statements. a. The length of DNA is usually defined as number of nucleotides or base pairs present in it. b. In DNA, every nucleotide residue has an additional -OH group present at 2' -position in the deoxyribose. c. Nuclein was discovered and named by Friedrich Meisher in 1969. d.
