Short Answer TypeName the enzyme and state its property that is responsible for continuous and discontinuous replication of the two strands of a DNA molecule.
Why is the enzyme cellulase needed for isolating genetic material from plant cells and not from the animal cells?
Describe the structure of a RNA polynucleotide chain having four different types of nucleotides.
Draw a schematic diagram of a part of double stranded dinucleotide DNA chain having all the four nitrogenous bases and showing the correct polarity.
It is established that RNA is the first genetic material. Explain giving three reasons.
RNA was the first genetic material in cells because:
i. RNA is capable of both storing genetic information and catalyzing chemical reactions
ii. Essential life processes (such as metabolism, translation, splicing, etc.), evolved around RNA.
iii. It has the tendency of self-replication.
