Answer #1

Answer for question number 19 : The correct option is A ( A complete set of genetic instructions on chromosomes in a cell). This term is in contrast with transcriptome ( complete set of RNA in a cell at a particular time) or Proteome complete set of proteins expressed by the cell at a particular time.

Answer for question number 17: The correct answer is option 4

Explanation : Histones are the basic proteins that contain high amounts of basic amino acids such as arginine and lysine. They play a role in packaging eukaryotic DNA into structural units called nucleosomes. There are five types of histone proteins in eukaryotic chromosomes namely, H1, H2A, H2B, H3 and H4. H1 is called the linker histone and highly conserved and the last four histones in copies of two forms the histone octamer found at the centre of nucleosome. Apart from its involvement in DNA packaging they also have a vital role in eukaryotic gene regulation which is brought about by acetylation and deacetylation of histone proteins

    2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
