Question

The RNA primer is used in

• A. translation
• B. replication
• C. conjugation
• D. transformation

Answer 1

Answer: (B)

replication

Answer 2

The RNA primer is used in replication of DNA. The new strands of DNA are formed in the $5 \to 2$ direction from the $3 \to 5$ template DNA by the addition of deoxyribonucleotides to the $7$ end of RNA primer. Translation is the process in living cells in which the genetic information encoded in nRNA in the form of a sequence of nucleotide triplets is translated into a sequence of amino acids in a polypeptide chain. It takes place on ribosomes in the cell cytoplasm. Conjugation is the fusion of two reproductive cells, particularly, when these are both of the same size. It is a form of sexual reproduction in some algae, some bacteria and ciliate protozoans. Transformation is a permanent heritable change in a cell, particularly a bacterial cell, that occurs as a result of its acquiring foreign DNA.
