As the homologous series is ascended, a member is reached which has the maximum activity, and the higher members are either entirely inactive or have very greatly reduced activity.

The alkanes, alkenes and cycloalkanes are examples of homologous series. A homologous series is a group of chemicals which have similar chemical properties and can be represented by a general ...

Save guides, add subjects and pick up where you left off with your BBC account. The alkanes are a homologous series with a structure based on a carbon chain - each carbon atom forms four covalent ...

Resolving the surface structure and chemistry of oxides such as strontium titanate has so far proved difficult. Rings of six or eight corner-sharing TiO4 tetrahedra and a homologous series of ...

The evidence that BRCA1 and BRCA2 are involved in DNA repair, in particular homologous recombination, is substantial. Both proteins co-localize with Rad51 to nuclear foci following DNA damage.

We found that sister chromatids serve as repair templates at high frequency (Johnson et al. Nature. 1999), but that homologous sequences on both homologous and nonhomologous chromosomes are also used, ...
