To identify the structural differences between these two molecules, its helpful to understand their roles in the building of a protein. (translation and transcription)Their roles give clues to the overall...

RNA polymerase scans the antisense DNA strand in the 3’ to 5’ direction, until it locates a promotor region. RNA polymerase then unwinds the DNA by breaking the hydrogen bonds between the complementary ba...

An enzyme is a protein that is a biological catalyst (meaning it speeds up the rate of a reaction). The most abundant enzyme on earth, Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), is an enzy...

In the 50's scientists didn't agree about which molecule - proteins or DNA - carry the hereditary genetic information. This experiment was designed to answer this question. It was known that bacteriophage...
