Short Answer TypeGroup the following as nitrogenous bases and nucleosides:
Adenine, Cytidine, Thymine, Guanosine, Uracil and Cytosine.
Depending upon the chemical nature of the template (DNA or RNA) and the nature of nucleic acids synthesised from it (DNA or RNA), list the types of nucleic acid polymerases.
List two essential roles of ribosome during translation.
Ribosome plays an essential role during translation in the following two ways:
i. It acts as the site for protein synthesis. The two subunits help in the synthesis of protein, the smaller subunit forms a protein synthesizing complex with mRNA , whereas the larger subunit acts as an amino acid binding site.
ii. Ribosome acts as a catalyst for forming peptide bond.
