Biology Question on biological classification
Which statement is correct for bacterial transduction:-
A
transfer of some genes from one bacteria to another bacteria through virus
B
transfer of genes from one bacteria to another bacteria by conjugation
C
bacteria obtained its DNA directly from mother cell
D
bacteria obtained DNA from other external source.
Answer
transfer of some genes from one bacteria to another bacteria through virus
Explanation
Solution
In transduction, genetic material of one bacterial cell goes to other bacterial cell by agency of bacteriophages or phages (viruses, infecting bacteria). Transduction was first of all reported in Salmonella typhimurium by Zinder and Lederberg (1952). Transduction is used for gene mapping and analysis in bacteria and also for strain construction.
