Human L1 retrotransposition: cis preference versus trans complementation.
Long interspersed nuclear elements (LINEs or L1s) comprise approximately 17% of human DNA; however, only about 60 of the approximately 400,000 L1s are mobile. Using a retrotransposition assay in cultured human cells, we demonstrate that L1-encoded proteins predominantly mobilize the RNA that encodes them. At much lower levels, L1-encoded proteins can act in trans to promote retrotransposition o...
متن کاملCis-trans Isomers of Vitamin
We have recently described the synthesis of rhodopsin in a solution containing four components: vitamin A, the precursor of the rhodopsin chromophore; opsin, the protein of rhodopsin; and liver alcohol dehydrogenase and cozymase, the enzyme and coenzyme which oxidize vitamin A to retinene (Hubbard and Wald, 1951). 1 This experiment was first performed with a fish liver 0il concentrate as the so...
متن کاملKinetics of the cis,cis to trans,trans isomerization of 1,1,2,2,5,5,6,6-octamethyl-1,2,5,6-tetrasilacycloocta-3,7-diene.
The kinetics of the ruthenium-promoted cis,cis to trans,trans isomerization of 1,1,2,2,5,5,6,6-octamethyl-1,2,5,6-tetrasilacycloocta-3,7-diene were investigated. Incubation of a ruthenium alkylidene complex, (Cy(3)P)RuCl(2)(==CHPh)Ru(p-cymene)Cl(2), in CD(2)Cl(2) for 5 days at 40 degrees C afforded a catalytically active ruthenium species that was shown to be responsible for promoting the isome...
متن کاملThe metabolism of cis- and trans-decalin.
1. The metabolism of cis- and trans-decalin in the rabbit has been investigated. 2. Both hydrocarbons were oxidized to racemic secondary alcohols and excreted as ether glucuronides in amounts equal to about 60% of the dose administered. The principal glucuronides were isolated as triacetyl methyl esters and as sodium salts. 3. cis-Decalin gave rise mainly to (+/-)-cis-cis-2-decalol, together wi...
متن کاملCis-trans effects induced by linkage disequilibrium.
This note concerns theoretical and experimental studies of multifactorial traits, especially fitness and its components, in which (1) the loci studied are only a subset of those relevant to the character of interest and (2) the genotypes at the loci studied are in nonrandom association (linkage disequilibrium) with genotypes at the loci ignored. In these cases, phenotypic differences between ci...
