The organelle that is the site of oxidative phosphorylation is:
A. Mitochondrion
B. Golgi apparatus
C. Nucleus
D. Ribosome
Answer: Option A
Solution (By JKSSB Mock Tests)
Oxidative phosphorylation occurs on the inner mitochondrial membrane, where the electron transport chain creates a proton gradient, and ATP synthase uses this gradient to produce ATP. This is the major source of cellular energy. Nucleus stores DNA, Golgi processes proteins, ribosomes synthesize proteins.
Consider the following statements about DNA fingerprinting:
1. It uses VNTRs (variable number tandem repeats).
2. It can be used in paternity testing.
3. It requires amplification by PCR.
Which of the above is/are correct?
Explanation:
Hydrophily is pollination by water and occurs in aquatic plants like Vallisneria and Zostera. Terrestrial plants do not use water for pollination. All other statements are correct.
Explanation:
Howard Temin and David Baltimore independently discovered reverse transcriptase in retroviruses in 1970, an enzyme that synthesizes DNA from RNA. Watson and Crick DNA structure, Mullis PCR.
