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

“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 ...

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.

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 ...

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 ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

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 ...
