A) translation
B) replication
C) transduction
D) transcription
Correct Answer: B
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 by Mathew Meselson ane Franklin Stahl in 1958in E. coli Transcription is the mode by which DNA passes its genetic information of 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 three 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 by Zinder and Lederberg in 1952.
