DNA is a genetic molecule. Yes, its right! Therefore any effect on the reproductive cells during replication of DNA will similarly have an effect of variation in the organism. But if any changes occur in the somatic cells of the body of any organism (muscle cells or skin cells etc.) it does not effect the next generations of the organism simply because there is no change in DNA. Similarly, in the case of mice experiment the tails were cut down (somatic cells) which didn't affect the genes. Therefore, the next generation also had tails as all mice have.

Although O2 does not participate directly in TCA cycle the cycle operates only when O present, why??

Posted by Shambhusingh Rathore 6 years, 5 months ago

CBSE > Class 11 > Biotechnology

1 answers

Ajitha Reghu 6 years, 4 months ago

Although O2 is not needed in TCA CYCLE but it stops in the absence of O2 because it runs out ofNAD and FAD and O2 is final acceptor of electron in ETC . Without oxygen it stops and NAD cannot be produced thereby causing glycolysis to produce lactic acid instead of pyruvic acid which is a necessary component of TCA cycle .thus kreb cycle is heavily dependent on O2 for its aerobic process
