DNA fingerprint

Overview page. Subjects: Ecology and Conservation.

A set of DNA-based characters which are in a combination unique, or nearly so, to an individual organism. See also satellite DNA.

See overview in Oxford Index

DNA markers

Overview page. Subjects: Medicine and Health.

1. Any unique sequence that can be used to identify a gene or chromosomal region including, among other things, single nucleotide polymorphisms (SNPs) and short tandem repeats...

ISSR

Overview page. Subjects: Medicine and Health.

Inter-simple sequence repeat, the region of the genome that lies between microsatellite loci.

See overview in Oxford Index

localized repeat sequences

Overview page. Subjects: Ecology and Conservation.

Repetitive DNA that occurs in a tandem array, often with a short repeating unit (e.g. satellite DNA).

See overview in Oxford Index

microsatellite

Overview page. Subjects: Genetics and Genomics — Chemistry.

Chromosomal sites that contain repeats of a small number of nucleotides arranged one after the other. The tandemly repeated motif usually contains between one and six nucleotides....

microsatellite DNA

Overview page. Subjects: Biological Sciences.

A form of highly repetitive DNA consisting of large numbers of very short base sequences scattered throughout the eukaryote genome. Each consists of a short base sequence, generally 2–6 bp...

minisatellite

Overview page. Subjects: Chemistry.

A repeat DNA segment comprising short head‐to‐tail tandem repeats giving variable number tandem repeat‐type polymorphisms, with approximate size between 1 and 30 kb. The name derives from...

MSI

Overview page. Subjects: Medicine and Health.

1. Microsatellite instability (see satellite DNA).

2. Magnetic source imaging, the reconstruction of current sources in the heart or brain from the...

repetitive DNA

Overview page. Subjects: Genetics and Genomics.

Any DNA sequence which occurs many times within a genome; it may be in a tandem array or dispersed repeats.

See overview in Oxford Index

repetitive sequence

Overview page. Subjects: Chemistry.

A repeated sequence of nucleotides found in the DNA of eukaryotes. There are various types. (1) Satellite DNA typically consists of tandem (head‐to‐tail) repeats of a few hundred...

saltatory conduction

Overview page. Subjects: Medicine and Health.

The means by which a nerve impulse is conducted rapidly through myelinated fibres. The wave of depolarization appears to leap from one node of Ranvier to the next.

satellite

Overview page. Subjects: Medicine and Health — Genetics and Genomics.

A distal chromosomal segment separated from the rest of the chromosome by a thin chromatic filament or stalk called the secondary constriction.

See overview in Oxford Index

simple sequence length polymorphism

Overview page. Subjects: Medicine and Health.

(SSLP)

Tandem repeat sequences that show polymorphism in the number of repeats in different individuals. Since the flanking sequences are the same in all individuals, PCR primers...

See overview in Oxford Index

slipped strand mispairing

Overview page. Subjects: Medicine and Health.

Mispairing of complementary DNA strands that can occur during replication. If the slippage is forwards then there will be deletion of bases, if backwards then there will be insertion. The...

STRP

Overview page. Subjects: Genetics and Genomics.

STR stands for short tandem repeat, and the method relies on the variability in the STRs that are scattered along the human chromosomes to distinguish the DNAs of different individuals. The...

tandem array

Overview page. Subjects: Ecology and Conservation — Zoology and Animal Sciences.

Repetitive DNA (deoxyribonucleic acid), where the repeating units are contiguous. Some genes of high copy number occur in tandem arrays (e.g. ribosomal DNA in eukaryotes). Satellite DNA is...

See overview in Oxford Index

tandem repeat

Overview page. Subjects: Chemistry.

Copies of DNA sequences (sometimes whole genes) or protein motifs that are adjacent to one another. See satellite DNA.
