Question

Match the answers below with the statements
a. Statement only refers to replication
b. Statement only refers to protein synthesis
c. Statement refers to both replication and protein synthesis
d. Statement refers to neither replication nor protein synthesis

7) Takes place only in the nucleus
8) Results in the formation of ATP
9) Requires RNA
10) Results in the destruction of a complete DNA strand
11) Results in the formation of a polypeptide
12) Only takes place in interphase before mitosis
13) Enzymes required for completion
14) Forms 2 identical polymers containing the base thymine
15) Involves transcription and translation

Answer 1

Ans.

a. only refers to replication-- forms 2 identical polymers containing the base thymine.

During the process of replication, there is formation of two daughter DNA molecules (two identical polymers) identical to parental DNA molecule. In DNA, thymine is present whereas thymine is replaced by uracil in RNA.

b. only refers to protein synthesis-- results in the formation of a polypeptide.

During protein synthesis (translation), there is formation of polypeptide using amino acids as monomeric unit. Polypeptide is nothing but the sequence of amino acids.

c.both replication and protein synthesis-- enzymes required for completion

Both replication and protein synthesis are enzyme mediated processes. There is requirement of different enzymes for completion of these processes.

d. neither replication nor protein synthesis-- results in the formation of ATP.

both replication and protein synthessis are not meant for energy production (ATP). Actually energy is needed for these processes.
