  2. Human genome - Wikipedia

    en.wikipedia.org/wiki/Human_genome

    It consists of 22 autosomes plus one copy of the X chromosome and one copy of the Y chromosome. It contains approximately 3.1 billion base pairs (3.1 Gb or 3.1 x 10 9 bp). [ 6 ] This represents the size of a composite genome based on data from multiple individuals but it is a good indication of the typical amount of DNA in a haploid set of ...

  3. Chromosome 9 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_9

    Chromosome 9 is one of the 23 pairs of chromosomes in humans.Humans normally have two copies of this chromosome, as they normally do with all chromosomes. Chromosome 9 spans about 138 million base pairs of nucleic acids (the building blocks of DNA) and represents between 4.0 and 4.5% of the total DNA in cells.

  4. Chromosome 22 - Wikipedia

    en.wikipedia.org/wiki/Chromosome_22

    Chromosome 22 was the first human chromosome to be fully sequenced. [4] Human chromosomes are numbered by their apparent size in the karyotype, with chromosome 1 being the largest and chromosome 22 having originally been identified as the smallest. However, genome sequencing has revealed that chromosome 21 is actually smaller than chromosome 22.

  5. Genome size - Wikipedia

    en.wikipedia.org/wiki/Genome_size

    Genome size ranges (in base pairs) of various life forms. Genome size is the total amount of DNA contained within one copy of a single complete genome.It is typically measured in terms of mass in picograms (trillionths (10 −12) of a gram, abbreviated pg) or less frequently in daltons, or as the total number of nucleotide base pairs, usually in megabases (millions of base pairs, abbreviated ...

  6. Second Generation Multiplex Plus - Wikipedia

    en.wikipedia.org/wiki/Second_Generation...

    An SGM Plus profile retrieved from a DNA database would just list the allele values: [4] 15,18; 6,9; 11,13; 22,22; 31,32.2; 14,17; 17,20; 11,12; 13,16.3; 15,16; XY Each value is the number of tandem repeats within the allele. A non-standard repeat is designated by the number of complete repeat units and the number of base pairs of the partial ...

  7. Small supernumerary marker chromosome - Wikipedia

    en.wikipedia.org/wiki/Small_supernumerary_marker...

    This derivative chromosome contains an exchange, termed t(11;22), or der22 (22) t (11;22), between the q arm of chromosome 22 around band 11.2 and the q arm of chromosome 11 around band 21. In ~10% of cases, carriers of this chromosome have a child with ES, with male and female carriers having 0.7% and 3.4%, respectively, chances of parenting ...

  8. G banding - Wikipedia

    en.wikipedia.org/wiki/G_banding

    G-banding, G banding or Giemsa banding is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosomes. It is the most common chromosome banding method. [1] It is useful for identifying genetic diseases (mainly chromosomal abnormalities) through the photographic representation of the entire chromosome ...

  9. Karyotype - Wikipedia

    en.wikipedia.org/wiki/Karyotype

    A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are generally organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography in the metaphase of the cell cycle , and results in a photomicrographic (or simply ...
