Forensic DNA profiling uses polymerase chain reaction (PCR) to amplify short tandem repeats (STRs), which are highly variable DNA regions, typically with four repeating bases. This variability helps ...

RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA ...

The RF is a multiprotein complex with helicase and DNA synthesis activities. It is called a fork because the structure resembles a two-pronged fork. The helicase activities unwind DNA in front of ...
