Glycolysis occurs in the cytoplasm, ETS on the inner mitochondrial membrane, protons accumulate in the intermembrane space and the Krebs cycle occurs in the mitochondrial matrix.
Which of the following statements are correct with respect to DNA separation, isolation and visualization?
(A) The cutting of DNA is done by molecular scissors. (B) The DNA fragments separate according to their size in an agarose gel upon electrophoresis. (C) The separated DNA fragments can be seen without staining when exposed to UV light. (D) The separated DNA fragments, when stained with ethidium bromide, can be seen under UV light.
Choose the correct answer from the options given below:
Restriction endonucleases are molecular scissors. DNA fragments separate by electrophoresis. Ethidium bromide-stained DNA fluoresces under UV light, not without staining.
Molluscs generally respire through gills, reptiles through lungs, adult amphibians through lungs and skin, and Amoeba carries out cellular respiration.
Insertion of a foreign DNA at BamHI site in an E. coli cloning vector pBR322 results in the loss of antibiotic resistance towards:
The BamHI restriction site lies within the tetracycline resistance gene (tetR) of pBR322. Insertional inactivation results in loss of tetracycline resistance.
Which of the following is not an example of convergent evolution?
Forelimbs of whales and bats are homologous organs that evolved from a common ancestor, representing divergent evolution. The other examples are analogous organs showing convergent evolution.
