More appropriately called interphase. The interval in the cell cycle between two cell divisions when the individual chromosomes cannot be distinguished, interphase was once thought to be the resting phase but it is far from a time of rest for the cell. It is the time when DNA is replicated in the cell nucleus.
In cytogenetics, the spontaneous rejoining of broken chromosomes to reconstitute the original chromosome configuration.
- Restriction endonuclease
An enzyme from bacteria that can recognize specific base sequences in DNA and cut (restrict) the DNA at that site (the restriction site). Also called a restriction enzyme.
- Restriction enzyme
An enzyme from bacteria that can recognize specific base sequences in DNA and cut the DNA at that site (the restriction site). A restriction enzyme acts as a biochemical scissors. Also called a restriction endonuclease. A restriction enzyme is a protein produced by bacteria that cleaves DNA at specific sites. Bacteria use restriction enzymes to […]
- Restriction fragment length polymorphism
A difference in DNA between people that can be recognized by the use of a restriction enzyme. Referred to as an RFLP.
- Restriction map
An array of sites in DNA susceptible to cleavage by diverse restriction enzymes.
