Once transcription is initiated, the DNA double helix unwinds and RNA polymerase reads the template strand, adding nucleotides to the 3′ end of the growing chain (Figure 2b). At a temperature of ...

DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific ...

This process of protein synthesis occurs in two stages - transcription and translation ... RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed ...

In all forms of life on earth, genetic information is composed of a four-letter alphabet—the nucleotides G, C, A, and T, which form the base pairs G-C and A-T. But three years ago, chemistry professor ...
