Plasmids, small circular DNA molecules found in bacteria, may contain antibiotic-resistance genes and have the ability to replicate independently. Bacteria can transfer these plasmids to one another, ...

A newly identified cellular system monitors subtle variations in genetic coding, hinting at a hidden level of control over ...

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 ...

Transcription and translation are processes a cell uses to make all proteins the body needs to function from information stored in the sequence of bases in DNA. The four bases (C, A, T/U, and G in the ...

Researchers show how a DNA-binding protein can search the entire genome for its target sequence without getting held up on the way. The result contradicts our current understanding of gene regulation ...

The origins of millions of tiny proteins in our bodies, previously assumed to be useless, have now been discovered. A study published on February 17 in the journal Molecular Cell describes how these ...
