How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. But ...

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 ...

All three RNAPs have catalytic cores consisting of 10 subunits. Five of these are core subunits which form crab claw shapes with DNA at their centres, channels for RNA products and NTP substrates as ...

Also, as the prokaryotic cell lacks a clearly defined nucleus and both transcription and translation takes place in the cytoplasm, there is no need to transport the mRNA to the cytoplasm after ...

Genes can be turned on and off as needed to adapt to environmental changes. But how do the different molecules involved interact with each other? Scientists present a candidate mathematical model for ...
