  2. Chromatid - Wikipedia

    en.wikipedia.org/wiki/Chromatid

    Once the paired sister chromatids have separated from one another (in the anaphase of mitosis) each is known as a daughter chromosome. The short arm of the right chromatid (3), and the long arm of the right chromatid (4), are also marked. Schematic karyogram of the human chromosomes, showing their usual state in the G 0 and G 1 phase of the ...

  3. Chromosome 6 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_6

    Chromosome 6 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 6 spans nearly 171 million base pairs (the building material of DNA ) and represents between 5.5 and 6% of the total DNA in cells .

  4. Low copy repeats - Wikipedia

    en.wikipedia.org/wiki/Low_copy_repeats

    In humans, chromosomes Y and 22 have the greatest proportion of SDs: 50.4% and 11.9% respectively. [2] SRGAP2 is an SD. Misalignment of LCRs during non-allelic homologous recombination (NAHR) [3] is an important mechanism underlying the chromosomal microdeletion disorders as well as their reciprocal duplication partners.

  6. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    Gene duplication is a major mechanism through which new genetic material is generated during molecular evolution. For example, the olfactory receptor gene family is one of the best-documented examples of pseudogenes in the human genome. More than 60 percent of the genes in this family are non-functional pseudogenes in humans.

  7. Neocentromere - Wikipedia

    en.wikipedia.org/wiki/Neocentromere

    For example, one may question whether the ring chromosomes present in tumors contain a neocentromere following a Class II deletion, because the neocentromere may or may not be present on the ring. As well as autosomes, human neocentromeres have also been observed in sex chromosomes, and correlate with some sex-linked diseases.

    Chromosome 16 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. People normally have two copies of this chromosome. Chromosome 16 spans about 90 million base pairs (the building material of DNA) and represents just under 3% of the total DNA in cells .

  9. Chiasma (genetics) - Wikipedia

    en.wikipedia.org/wiki/Chiasma_(genetics)

    In genetics, a chiasma (pl.: chiasmata) is the point of contact, the physical link, between two (non-sister) chromatids belonging to homologous chromosomes. At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis. [1]
