  4. Dtranscription

Correct answer

B. replication

Step-by-step solution

DNA multiplication or duplication of DNA takes place by replication. It takes place during S-phase of interphase during cell-cycle. DNA replication is semi-conservative was strongly evidenced byMathew Meselson andFranklin Stahl in 1958 in E. coli.Transcription is the mode by which DNA passes its genetic information to mRNA. It is the first step in protein synthesis which takes place in nucleus of eukaryotic cells.Translation is the synthesis of a chain of polypeptide by mRNA. It is the process when protein synthesis takes place at the site of ribosomes. It involves 3 steps initiation, elongation and termination.Transduction is the transfer of genes from one bacterial cell to another by means of a virus. Transduction was discovered byZinder andLederberg in 1952.
