In these early electron micrographs, the DNA molecules appear as "trunks," with many RNA "branches" extending out from them. When DNAse and RNAse (enzymes ... types of RNA polymerase exist in ...

Protein synthesis is vital for life, translating genetic information from DNA to functional proteins through transcription ...

Enzymes called RNA polymerases transcribe ... There are a variety of different types of RNA polymerases that can transcribe different types of RNA. RNA polymerase II, shown here, is responsible for ...

Northwestern Medicine investigators have discovered a novel mechanism that recognizes and eliminates "bad" transcriptional elongation enzymes during gene expression, findings that may inform the ...

For a gene to be switched on, it must be acted upon by an enzyme called RNA polymerase. This is a molecular machine which can read DNA and create ... Northwestern Medicine investigators have ...

For this reason, the lagging strand polymerase requires the action of a DNA primase enzyme before it can start each Okazaki fragment. The primase produces a very short RNA molecule (an RNA primer ...

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 ...
