Amplified fragment length polymorphism (AFLP-PCR or AFLP) is a PCR-based tool used in genetics research, DNA fingerprinting, and in the practice of genetic engineering. Developed in the early 1990s by KeyGene, [1] AFLP uses restriction enzymes to digest genomic DNA, followed by ligation of adaptors to the sticky ends of the restriction fragments.
DNA profiling is a forensictechnique in criminal investigations, comparing criminal suspects' profiles to DNA evidence so as to assess the likelihood of their involvement in the crime. [1][2]It is also used in paternity testing,[3]to establish immigration eligibility,[4]and in genealogicaland medical research.
DNA footprinting is a method of investigating the sequence specificity of DNA -binding proteins in vitro. This technique can be used to study protein-DNA interactions both outside and within cells. The regulation of transcription has been studied extensively, and yet there is still much that is unknown.
Microfluidic Sanger sequencing is a lab-on-a-chip application for DNA sequencing, in which the Sanger sequencing steps (thermal cycling, sample purification, and capillary electrophoresis) are integrated on a wafer-scale chip using nanoliter-scale sample volumes. This technology generates long and accurate sequence reads, while obviating many ...
Alec Jeffreys. After finishing his doctorate, he moved to the University of Amsterdam, where he worked on mammalian genes as a research fellow, [16] and then to the University of Leicester in 1977, where in 1984 he discovered a method of showing variations between individuals' DNA, inventing and developing genetic fingerprinting.
The fundamental autosomal number or autosomal fundamental number, FNa[36]or AN,[37]of a karyotype is the number of visible major chromosomal arms per set of autosomes(non-sex-linked chromosomes). Ploidy. [edit] Ploidyis the number of complete sets of chromosomes in a cell. Polyploidy, where there are more than two sets of homologous chromosomes ...
The northern blot, or RNA blot, [1] is a technique used in molecular biology research to study gene expression by detection of RNA (or isolated mRNA) in a sample. [2][3] With northern blotting it is possible to observe cellular control over structure and function by determining the particular gene expression rates during differentiation and ...
In molecular biology, restriction fragment length polymorphism (RFLP) is a technique that exploits variations in homologous DNA sequences, known as polymorphisms, populations, or species or to pinpoint the locations of genes within a sequence. The term may refer to a polymorphism itself, as detected through the differing locations of ...
