The ribosomes,mount of RNA and the protein synthesizing capacity of the cell. In the 1940s, Brachet and Caspersson established unequivocally this correlation with materials as diverse as the root tips of ., imaginal disks of . larvae, secreting pancreatic cells and silk glands from the silkworm and with various m

The genetic code, the transfer RNAs and the aminoacyl-tRNA-synthetases, not bear on the messenger RNA, but on ribosomal RNA. Nevertheless, it is thanks to them that this connection became familiar. Then Beadle formulated the hypothesis called the “one gene-one enzyme correlation”, but his ideas did never reach the formulation of a linear code relating genes and protein

Attenuation,level of transcription depended on the intracellular level of tRNAhis charged by histidine. These observations have been confirmed and extended by Kasai in 1974. In the case of the . operon, observations made from 1973 to 1976 indicated that repression could not be the only way by which . regulates

Bacterial growth,When cells are inoculated from an agar slant into a synthetic medium, a certain time elapses before cells grow at a constant rate. This time is called the lag phase during which no growth is first detected and then cells experience an accelerating growth rate before the constant rate is established.

Glycolysis, gluconeogenesis and glycogen synthesis,The bacterial glycogen phosphorylase is a pyridoxal phosphate enzyme that transform glycogen to glucose 1-phosphate, which is then transformed to glucose-6-phosphate, a normal intermediate of glycolysis.
