DNA mutiplication is called

  • translation

  • replication

  • transduction

  • transcription

Solution

B.

replication

DNA multiplication takes place by replication at S- phase of interphase during cell cycle. It is semi- conservative in nature.

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 takes place at the site of ribosomes and involves three steps- Initiation, Elonagtion and Termination.

Transduction is the transfer of genes from one bacterial cell to another by means of a virus.
