Meselson and Stahlʹs experiments involved growing E. coli on a medium containing 15N (heavy nitrogen) which increased the density of the bacterial DNA. Cells were then grown on a medium containing only 14N. DNA samples were obtained for analysis after one, two and three rounds of replication (generations) and centrifuged on a density gradient. The double-helical DNA forms bands in the gradient depending on its density. How many bands did Meselson and Stahl see after two generation of cells were grown on the 14N medium?

Rubisco catalyzes both the carboxylation and the oxygenation of ribulose 1,5-bisphosphate, the oxygenase activity of rubisco causes partial loss of the carbon fixed by the Calvin–Benson cycle, to avoid loss a reaction takes place such as photorespiration, The following statements about photorespiration.
a.) To avoid drain of carbon out of the Calvin–Benson cycle is metabolized through the C2 oxidative photosynthetic carbon cycle
b.) In photorespiration involves chloroplasts, leaf peroxisomes, and mitochondria
c.) During oxygenation process Rubisco fixes oxygen at high temperature
d.) One of the rection of the C2 cycle is Glycine converted into the serine is takes place in peroxisome
