Question

The Pneumococcus experiment proves that (1)Bacteria do not reproduce sexually (2)RNA sometime controls the production of DNA and proteins (3) DNA is the genetic material (4)Bacteria undergo binary fission

Answer 1

Answer:

DNA is the genetic material

Explanation:

Griffith proved that DNA is genetic material by his transformation experiment on virulent (SIII) and non-virulent strains (RII) of Diplococcus pneumoniae. Griffith infected mice with a mixture of virulent (SIII) and non-virulent strains (RII) of pneumococcus bacteria, Diplococcus pneumoniae. Heat killed SIII did not cause any infection but a mixture of heat-killed SIII and living RII strains caused infection because a transforming substance was transferred from heat-killed strain to non-virulent strain causing non-virulent strain to transform into a virulent form which was identified as DNA by McCleod and McCarty; . Binary fission is the method of asexual reproduction in bacteria;  Sexual reproduction in bacteria occurs by conjugation, transformation and transduction;. RNA retroviruses have reverse transcriptase enzyme that synthesizes a DNA copy (cDNA) of viral RNA which is then transcribed and translated; the viral RNA controls the synthesis of DNA and protein;

Answer 2

Answer:

DNA IS THE GENETIC MATERIAL.
