In mice Igf2 gene which encodes a protein called insulin like growth factor II (Igf2). Offspring inherit one Igf2 allele from their mother and one from their father The paternal copy of Igf2 is actively expressed in the fetus, but the maternal copy is not expressed. which of the following is correct about this gene?

a) this is an example of genomic imprinting and showing maternal imprinted

b) this is an example of genomic imprinting and showing paternal imprinted

c) mechanism of imprinting is due to the addition of methyl (CH3) groups to DNA nucleotides

d) mechanism of imprinting is due to changing the nucleotide sequences

Out of these which of the following is true regarding the propensity of α-helix.

a. any amino acid which can take up desirable ϕ and ψ angle close to -57 and -47 will favour the formation of a α-helix

b. amino acid such a proline and glycine have lowest propensity will favour formation of α-helix.

c. if the resultant change in the value ΔΔG0 is positive then it will favour the formation of α-helix.

d. if the resultant change in the value ΔΔG0 is zero or close to zero then it will favour the formation of α-helix.
