Which of the following statements is correct?
I. The biochemical nature of genetic material was not defined from the experiments conducted by Griffith
II. Working on transformation Avery et al concluded DNA is genetic material but not all biologists were convinced
III. RNA is the genetic material in TMV, QB bacteriophage etc.
IV. DNA is the predominant genetic material while RNA performs dynamic functions of messenger adapter
V. Viruses having DNA genome and having shorter life span mutate and evolve faster
(1) All are correct             

(2) I and II             

(3) All except V               

(4) III and IV

The force that holds DNA together in a double helix is:

(1) The force of the twist                   

(2) Covalent bonds

(3) Ionic bonds or ionic interactions   

(4) Hydrogen bonds

Experiments by Avery, Macleod, and McCarty supported DNA as the genetic material by showing that:
(1) Both protein and DNA samples provided the transforming factor

(2) DNA was not complex enough to be the genetic material

(3) Only samples with DNA provided transforming activity

(4) Even though DNA was molecularly simple, it provided adequate variation to act as the genetic material

SNP which is pronounced as "snips” stands for:

(1) Small nuclear protein                   

(2) Single nucleotide particle

(3) Single nucleotide polymorphism   

(4) Small nicking points

The length of E. coli DNA and length of DNA in a human 2N cell is:

(4) 1.36 cm and 2.2 cm respectively
