Describe Seymour Brenner's contribution to cracking the genetic code with respect to translation.
11Alexandr11 [23.1K]

Seymour Benzer used phage T4 mutants, Experimental evidence that a gene is a linear sequence of nucleotide pairs. Some regions of chromosomes have "hot spots" for mutations. Benzer's experimental approach to fine structure mapping of the rII locus.  Generated 1612 spontaneous point mutations and several deletions in rII locus identified two complementation groups, rIIA and rIIB.  Mapped locations of deletions relative to each other using recombination.  Mapped locations of point mutations relative to the deletions. Tested for recombination between all point mutations within the same complementation group.

Natali [406]
The correct sequence is; Glycolysis-pyruvate-acetyl CoA-krebs cycle-electron transport chain. 
Glycolysis is a sequence of reactions for the breakdown of glucose to two molecules of pyruvic acid under aerobic conditions, Krebs cycle is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the energy carriers, while electron transport chain involves a series of complexes that transfer electrons from electron donors to electron acceptors via redox reactions and couples this transfer with the transfer of protons across a membrane.
