The part of an enzyme molecule that carries out the catalystic prosesses.
Amount of energy stored in chemicals required for a reaction to be processed.
Position on a chromosome occupied by a gene.
The final chemical produced after several stages of a reaction.
An inducer binds to the repressor allowing the gene to be transcribed.
The chemical compound that is reacted with the enzyme.
Enzyme that unwinds the DNA before and during it's replication.
Short segment of nucleotide attach on to the template strand for corresponding DNA nucleotides to follow.
DNA polymerase III
Catalysing the formation of DNA from it's nucleotide sub-units for both strands.
Releives the strain of the replication fork by cutting, winding and rejoining the DNA strands.
Short segments of DNA formed in the replication process on lagging strand.
Nucleotides connect onto the parent strand starting with the 3' end of the parent strand moving toward the 5' end.
Nucleotides are assembled in segments.
Joins DNA fragments together 'fills gap'
Nucleotides are assembled non-stop
DNA polymerase I
Catalysing to form nucleotide sub-units once the RNA primer is removed to fill the gaps.
