What are microsatellites?

What are microsatellites?

Microsatellite, as related to genomics, refers to a short segment of DNA, usually one to six or more base pairs in length, that is repeated multiple times in succession at a particular genomic location. These DNA sequences are typically non-coding.

What is the best the definition of a microsatellite?

Listen to pronunciation. (MY-kroh-SA-teh-lite) A short sequence of DNA, usually 1 to 4 basepairs (a unit of DNA), that is repeated together in a row along the DNA molecule. There is variation from person to person in the number of repeats.

How are microsatellites used in population genetics?

Microsatellites are also being used as genetic markers for identification of population structure, genome mapping, pedigree analysis, and to resolve taxonomic ambiguities in many other animals besides fishes [40–49].

What is a microsatellite quizlet?

Microsatellites are short sequences of DNA that consist of several two- or three- nucleotide motifs repeated in tandem (for example, AATAATAAT or GAGAGAGAGAGA). Each allele consists of a different number of repeats. Microsatellites are typically not under selection, and they are inherited through Mendelian inheritance.

How are microsatellites used in genetic studies quizlet?

Once a microsatellite and its flanking sequences have been identified, DNA samples from a set of individuals in the population can be analyzed to determine the number of repeats that are present in each individual.

Are microsatellites used to determine relationships?

Microsatellite genotypes are useful for estimating the relationship and relatedness between individuals of unknown ancestry. Current relationship/relatedness estimators either assume that genotypes are error-free (Thompson, 1991) or that genotyping error is rare (Boehnke and Cox, 1997; Marshall et al, 1998).

What is a microsatellite in genetics?

Listen to pronunciation. (MY-kroh-SA-teh-lite) Repetitive segments of DNA scattered throughout the genome in noncoding regions between genes or within genes (introns).

What is a microsatellite quizlet Labster?

What is a microsatellite? a repeating sequence of 2-6 base pairs of DNA. We want to analyze four different microsatellites using four different primer pairs in two samples and prepare a master mix for each set.

What is a microsatellite Labster?

Microsatellites are short repeating DNA sequences of two to six base pairs. The numbers of repeats can vary among individuals; they represent the different alleles. For example, allele 1 has four repeats, allele 2 has five repeats, allele 3 has six repeats, and so forth.
