There is more sequence divergence in mitochondrial than in nuclear DNA (Brown et al., 1993; Giulietta et al., 2000). This may be caused by a faster mutation rate in mtDNA that may result from a lack of repair mechanisms.

WitrynaSolution. If an inheritable mutation appears in a population at high frequency, this is known as DNA polymorphism. Since inheritable mutations finally lead to evolution, hence study of DNA polymorphism is important from the evolutionary perspective. Was this answer helpful? WitrynaVariable number tandem repeat (VNTR): Locations in a genome where a short sequence of nucleotides is repeated adjacent to each other. The length of such a repeat is inherited and is termed functional when it influences gene expression. For 5-HT, the 5-HTT linked polymorphic region (5-HTTLPR) is the most commonly investigated VNTR. chuck palahniuk face tattoosWitrynaOnce amplified, polymorphisms and mutations in the sequence can be detected by DNA sequencing, either directly or after screening for variation with a method such as … chuck palahniuk invisible monsters remix

WitrynaA gene is said to be polymorphic if more than one allele occupies that gene's locus within a population. [1] In addition to having more than one allele at a specific locus, each allele must also occur in the population at a rate of at least 1% to generally be considered polymorphic.
