BIOL 2040 Lecture Notes - Lecture 24: Sister Chromatids, Homologous Chromosome, Mitosis
Document Summary
You should be able to explain these terms in simple words, like you are talking to a 5- year-old. Homologous chromosome: pairs of chromosomes, one from your mother one from your father. Chromosomal arms (p and q arms): p is the short arm and q is the long arm of chromosomes when replicated and joined as two sister chromatids. Metacentric: center position of centromere on joining sister chromatids. Submetacentric: midway between meta and acro centric regions where cetnromere can be found. Acrocentric: high up but not at the tip of sister chromatid attachment. Telocentric: when sister chromatids are attached by the ends. Diploid number (2n), haploid number (n): some species carry single chromosomes making them haploid, while other carry matching pairs one from father one from mother making them diploid. Karyotype: the shape, size, and number of chromosomes of a species.
