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 ...

With this technique, biotin-labelled nucleotides are added to growing RNA strands, abruptly terminating transcription. These biotin labels serve as markers that discriminate newly formed RNA from ...

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 ...

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 ...

GTP is also a substrate for the synthesis of RNA during transcription. Purine metabolism involves the synthesis and breakdown of purine nucleotides in cells. Disorders of purine metabolism can lead to ...
