- DNA strand displacement
The rejection of the broken 3' single-strand DNA molecule that formed heteroduplex DNA with its complement in an intact duplex DNA. The Watson-Crick base pairing in the original duplex is restored. The rejected 3' single-strand DNA molecule reanneals with its original complement to reform two intact duplex molecules.
- B-1b B cell differentiation
The process in which B cells acquire the specialized features of B-1b B cells. B-1b B cells are B-1 cells that do not express CD5.
- B-1a B cell differentiation
The process in which B cells acquire the specialized features of B-1a B cells. B-1a B cells are B-1 cells that express CD5 and arise from fetal liver precursors.
- meiotic strand displacement
The cell cycle process in which the broken 3' single-strand DNA molecule that formed heteroduplex DNA with its complement in an intact duplex DNA is rejected. The Watson-Crick base pairing in the original duplex is restored. The rejected 3' single-strand DNA molecule reanneals with its original complement to reform two intact duplex molecules. This occurs during meiosis.
- DNA strand invasion
The process in which the nucleoprotein complex (composed of the broken single-strand DNA and the recombinase) searches and identifies a region of homology in intact duplex DNA. The broken single-strand DNA displaces the like strand and forms Watson-Crick base pairs with its complement, forming a duplex in which each strand is from one of the two recombining DNA molecules.
