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 ...
If our genes are so similar, what really makes a eukaryote different from a prokaryote, or a human from E. coli? The answer lies in the difference in gene expression and regulation used. Regulation of ...
Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from ...
The BRCA1 gene is a sequence located on the long arm of chromosome 17, at position 17q21. The gene spans around 100 kilobases and codes for a tumor suppressor protein containing 1863 amino acids. This ...
Convergent transcription induces transcriptional gene silencing in fission yeast and mammalian cells
RNA interference (RNAi) in eukaryotes can be elicited by either cytoplasmic post-transcriptional gene silencing (PTGS) or nuclear transcriptional gene silencing (TGS) mechanisms. PTGS is related to ...
