In (+)-stranded RNA viruses ... of nucleotide incorporation. Polymerase residues that change conformation upon dNTP binding include an extended loop in HIV-1 RT 17. In contrast, residues altering ...

Northwestern Medicine investigators have discovered a novel mechanism that recognizes and eliminates "bad" transcriptional elongation enzymes ... elongation by RNA polymerase II (Pol II), in ...

Single-Molecule Footprinting reveals that RNA polymerase II (Pol II) occupancy is infrequent at mouse promoters. This results ...

The process of transcription can be visualized by electron microscopy (Figure 1); in fact ... with many RNA "branches" extending out from them. When DNAse and RNAse (enzymes that degrade DNA ...

An enzyme called RNA polymerase deciphers this code and converts it into RNA, a molecule that closely resembles DNA. This transfer of life's code from DNA to RNA is called transcription.

“It’s definitely a key advance in the field of understanding what RNA polymerase ribozymes can do, and it has pretty important implications for the RNA world theory,” he added. Study coauthors Gerald ...

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 ...
