Which statement is correct for bacterial transduction. -
1 Transfer of some genes from one bacteria to another bacteria through virus
2 Transfer of some genes from one bacteria to another bacteria by conjugation
3 Bacteria obtained its DNA directly
4 Bacteria obtained DNA from other external source
Explanation:
In transduction, transfer of genetic material from one bacteria to another by virus (bacteriophage). It was discovered by Joshua Lederberg and Norton Zinder while working on the recombination of genes in bacteria and this technique of transfer viral DNA and applied to the bacterium Salmonella typhimurium. - Transduction is used for gene mapping \(\&\) analysis in bacteria and also for strain construction.

One gene-one enzyme relationship was established for the first time in:
1 Diplococus pneumoniae
2 Neurospora crassa
3 Salmonella typhimurium
4 Escherichia Coli
Explanation:
One gene one enzyme hypothesis given by Beadle and Tatum in 1941 and for this discovery they got Nobel Prize in 1958. - Function of a one gene is direct the formation of one enzyme. - This experiment used in Red bread mold Neurospora crassa.

In 1944, Avary, McCarty and MacLeod isolated a substance from heat killed virulent form of bacteria and added to non-virulent to virulent from this substance can be distroyed by:
1 DNAase
2 protease
3 lipase
4 amylase
Explanation:
Avary, McCarty, and MacLeod are the researchers who conducted experiments that demonstrate that the mutation principle is DNA when it was widely accepted that it was a protein with the ability to provide genetic information. They declared that DNA is a substance that results in the transformations of a bacteria from a non-virulent form to a virulent one.

The transforming principle of Pneumococcus as found out by Avery, MacLeod and McCarty was
1 mRNA
2 DNA
3 protein
4 Polysaccharide
Explanation:
Avary, MacLeod and McCarty demonstrate that DNA is responsible for bacterial transformation. could transform from one strain in to a different strain. This phenomenon he attributed to an unidentified transforming principle or transforming factor.
