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 ...
Chromatid pairs are normally genetically identical, and said to be homozygous. However, if mutations occur, they will present slight differences, in which case they are heterozygous . The pairing of chromatids should not be confused with the ploidy of an organism, which is the number of homologous versions of a chromosome.
Schematic karyogram of a human as seen on G banding, with annotated bands and sub-bands.It is a graphical representation of the idealized human diploid karyotype. Each row is vertically aligned at centromere level.
Human karyogram, with each row vertically aligned at centromere level, and with annotated bands and sub-bands. It is a graphical representation of the idealized human diploid karyotype. It shows dark and white regions on G banding. It shows both the female (XX) and male (XY) versions of the sex chromosome
The following are some of the gene count estimates of human chromosome 13. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction).
ESCO1: encoding protein Establishment of sister chromatid cohesion N-acetyltransferase 1; FECH: ferrochelatase (protoporphyria) GREB1L: encoding protein Growth regulation by estrogen in breast cancer-like; HAUS1: HAUS augmin-like complex subunit 1; HDHD2: encoding enzyme Haloacid dehalogenase-like hydrolase domain-containing protein 2
English: Schematic and relatively language-neutral karyogram of a human. For each chromosome pair, the scale to the left shows the length in terms of million base pairs, and the scale to the right shows the designations of the bands and sub-bands. It shows dark and white regions as seen on G banding.
Chromosome 15 is one of the 23 pairs of chromosomes in humans.People normally have two copies of this chromosome. Chromosome 15 spans about 99.7 million base pairs (the building material of DNA) and represents between 3% and 3.5% of the total DNA in cells.
