RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA ...

An analogous process occurs during chromosomal DNA replication, whereby the 5’-RNA segments that prime discontinuous synthesis of Okazaki fragments are excised, and the intervening gaps are filled in ...

ATP-dependent RNA ligases join 3’-OH and 5’-PO 4 RNA termini via three nucleotidyl transfer steps similar to those of DNA ligases: (Step 1) ligase reacts with ATP to form a covalent ...

Rifaximin is a semi-synthetic derivative of rifampin and acts by binding to the beta-subunit of bacterial DNA-dependent RNA polymerase blocking one of the steps in transcription. This results in ...

This unwinding of the helix is caused by an enzyme (helicase enzyme). The enzyme RNA polymerase attaches to the DNA in a non-coding region just before the gene. RNA polymerase moves along the DNA ...

The human genome is a molecule in action; the strands separate when they are being copied for cell division; DNA has to be carefully packaged to fit ... | Genetics And Genomics ...
