Performed the experiments: These two lectins are coded by genes that are located within a lectin family genes cluster on chromosome 19p13.

During electrophoresis, DNAs which are negatively charged migrate toward the positive electrode. Evol Bioinform Online 1: Boerwinkle W, Fourest E, Chan L 1989 Rapid typing of tandemly repeated hypervariable loci by the polymerase chain reaction: Single locus probes are usually tagged with a radioactive label for easy detection, and are chosen to detect one polymorphic genetic locus on a single human chromosome.

The effect of a stacking gel, the pH and cross-linking agent concentration on the resolution and sharpness of PCR amplified VNTR alleles in a vertical discontinuous polyacrylamide gel electrophoresis system was investigated. View Article Google Scholar 3.

By defining the northeastern Bantu of Kenya as the Human Original region population, we calculated the genetic distance between the other 25 non-African populations and the original population East African population. Correlation analysis between the graphical distance and genetic population distance was carried out using Pearson bivariate correction analysis SPSS for Windows; 13.

According to the sequence identity in the 69-bp repeat unit, seven other haplotypes are identified denoted as H1—H8 Figure 1.

Paternity testing with VNTR DNA systems

Genetic association studies also showed conflicting results about the associations of length variation of neck-region and several infectious diseases, such as HIV, HCV, and SARS [11] — [19]. The experimental steps used in a forensics laboratory for DNA profile analysis are as follows: J Immunol 165: Author Contributions Conceived and designed the experiments: Figure 3.

When the longer repeat alleles were compared with the shorter one, it is apparent that the expansion of VNTR is due to insertion of H2 subunit e. However, we showed that a different mechanism, namely demographic migration might explain equally well the generation of the VNTR diversity based on the sequence subunits within the VNTR repeats.

Further analysis showed that the present worldwide diversity profile of this VNTR locus could be resulted from demographic migrating of different tribes, and no evidence was found to support the notion of multiple independent mutation events at this VNTR due to natural selection.

The proportion of the common consensus configuration, minor variant and major rearrangement in VNTR.
