1967 Science 8 Sept. 1177/3 Enzyme systems which excise regions of hybrid DNA in which there are nucleotide mispairs.

1975 Nature 18 Dec. 645/2 These irregular (aberrant) segregations are usually attributed to gene conversion involving hybrid DNA formation at the heterozygous site, with or without enzymatic correction of the resulting base mispairs.

1987 Science (Nexis) 23 Oct. 498 The efficiency of repair depends both on the nature of the mispair and on the flanking DNA sequences.

1990 Nucleic Acids Res. 18 4081/1 In all sequences studied here containing a wobble mispair, the purine base at the mispair site shifts into the minor groove.

2000 Mutation Res. 461 41 Transfected plasmid DNA containing either a U:G mispair or U:A base pairs was efficiently repaired in the control lines.

1966 Proc. National Acad. Sci. U.S.A. 55 286 At each DNA replication only about 10 per cent of the AP bases would ‘mispair’ with C.

1976 Nature 23 Sept. 787/2 This analogue..can interact ‘normally’ with T on the template to form a complementary pair with two H bonds. By tautomerism to the imino form, it can ‘mispair’ with C also by way of two H bonds.

1999 S. Jones Almost like Whale vi. 150 In places with many copies of a particular string of letters, the segments tend to mispair, rather like the teeth of a zip-fastener done up too quickly.

1993 Toronto Star (Nexis) 24 Apr. sw 12 Dolly's mispaired with James Woods, who shines in creepy dramas, but lacks a light comedic touch.
