Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote and eukaryote expression end. Central to the ...

This image illustrates the process of gene transcription within a cell. The DNA double helix unwinds to expose a specific sequence, allowing RNA polymerase to synthesize a complementary pre-mRNA ...

The capabilities of organisms to contend with environmental changes depend on their genes and their ability to regulate their expression. DNA-binding transcription factors (TFs) play a central role in ...

Proteins are essential biological molecules that perform a vast array of functions crucial for life, from catalyzing ...

The regulation of mRNA transcription plays a key role in relaying signals from the environment and during development into the gene expression program of a cell. During transcription initiation, a ...
