The relative order of base pairs, whether in a DNA fragment, gene, chromosome, or an entire genome.
See also: base sequence analysis.
Industry:Biology
Twins produced by the division of a single zygote; both have identical genotypes. See also: fraternal twin.
Industry:Biology
A sequence of DNA similar to a gene but nonfunctional; probably the remnant of a once-functional gene that accumulated mutations..
Industry:Biology
Using the immune system to treat disease, for example, in the development of vaccines. May also refer to the therapy of diseases caused by the immune system. See also: cancer.
Industry:Biology
Traits or diseases associated with the X or Y chromosome; generally seen in males. See also: gene, mutation, sex chromosome.
Industry:Biology
Unit of length for DNA fragments equal to 1 million nucleotides and roughly equal to 1 cM. See also: centimorgan.
Industry:Biology
The process of two consecutive cell divisions in the diploid progenitors of sex cells. Meiosis results in four rather than two daughter cells, each with a haploid set of chromosomes. See also: mitosis.
Industry:Biology
The study of human genetics by comparisons with model organisms such as mice, the fruit fly, and the bacterium E. coli..
Industry:Biology
A stage in mitosis or meiosis during which the chromosomes are aligned along the equatorial plane of the cell..
Industry:Biology
Nucleic acid base sequence that can form a double-stranded structure with another DNA fragment by following base-pairing rules (A pairs with T and C with G). The complementary sequence to GTAC for example, is CATG..
