ANSWER :
7. DNA (Deoxyribonucleic acid) is the genetic material in most
of the organisms and generally found in the form of double helix
that contain four nitrogenous bases (cytosine, adenine, guanine and
thymine) except uracil, which present in RNA (Ribonucleic acid).
Hence statement (E) is not true regarding DNA.
8. A gene is physically located on the
chromosome in th nucleus of a cell.
9. RNA (Ribonucleic acid) is a vital macrobiomolecule which
regulate several biochemical processes in the cell, it composed of
ribose sugar, four nitrogenous bases (Adenine, Guanine, Cytosine
& Uracil) and one phosphate group. RNA generally found in the
form of single strand hence, never forms the helix.
10. The ‘Uracil’ is a nitrogenous base that found only in the
RNA (Ribonucleic acid) but not present in the DNA. It binds to
adenine (complementary base).
