Gel electrophoresis

... same speed, which usually means they are about the same size. There are special markers available, which contain molecules of known sizes. If such a marker was run on one lane in the gel parallel to the mixture(s), the bands it displays can be compared to those of the mixture(s) in order to determine ...

Genetics

... number of genes are known as quantitative traits, and their mapping to a location on the chromosome requires accurate phenotypic, pedigree and marker data from a large number of related individuals. Ecological genetics again builds upon the basic principles of population genetics but is more ...

Isozyme

... (such as direct DNA sequencing , Single nucleotide polymorphisms and microsatellites ), they are still amongst the quickest and cheapest marker systems to develop, and remain (as of 2005 ) an excellent choice for projects that only need to identify low levels of genetic variation, e.g. ...

Primer

... a DNA strand. A sequencing method called dideoxy sequencing (also known as chain termination method or Sanger method ) uses a primer as a start marker for the chain reaction. In polymerase chain reaction (PCR), primers are used to determine the DNA fragment to be amplified by the PCR process. The ...
