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 ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Real image of DNA molecules being copied in human cells, visualized by immunofluorescence microscopy. The yellow arrows mark where replication begins, and the white arrows indicate the direction in ...
