| rec A protein | <protein> A protein (40 kD) product of the rec (recombination) gene, that catalyses the pairing of a single stranded piece of DNA with its complementary sequence, displacing a loop of single stranded DNA (D loop). It catalyses the ATP-driven exchange of DNA strands in genetic recombination. The product of the reaction consists of a duplex and a displaced single-stranded loop which has the shape of the letter d and is therefore called a d-loop structure. ATP is hydrolyzed to ADP during the reaction; also has proteolytic activity. (22 Sep 2002) |
| rec B protein | <protein> Protein (140 kD), one subunit of nuclease that unwinds double stranded DNA and fragments the strands sequentially, the other subunit is recC (128 kD) (18 Nov 1997) |
| london | The capital city of England. <medicine> London paste, a paste made of caustic soda and unslacked lime; used as a caustic to destroy tumours and other morbid enlargements. London pride. <botany> A cruciferous plant (Sisymbrium Irio) which sprung up in London abundantly on the ruins of the great fire of 1667. Source: Websters Dictionary (01 Mar 1998) |
| london dispersion forces | <chemistry> The forces that exist in nonpolar molecules that involve an accidental dipole that induces a momentary dipole in a neighbor. (09 Jan 1998) |
| London forces | First postulated by van der Waals in 1873 to explain deviations from ideal gas behaviour seen in real gases; the attractive force's between atoms or molecules other than electrostatic (ionic), covalent (sharing of electrons), or hydrogen bonding (sharing a proton); generally ascribed to dipolar and dispersion effects, π-electrons, etc.; these relatively nondescript force's contribute to the mutual attraction of organic molecules. Synonym: London forces. (05 Mar 2000) |
