Chromosome 3 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 3 spans more than 198 million base pairs (the building material of DNA ) and represents about 6.5 percent of the total DNA in cells .
•List of human protein-coding genes page 2 covers genes EPHA1–MTMR3 •List of human protein-coding genes page 3 covers genes MTMR4–SLC17A7 •List of human protein-coding genes page 4 covers genes SLC17A8–ZZZ3 NB: Each list page contains 5000 human protein-coding genes, sorted alphanumerically by the HGNC-approved gene symbol.
In genetics, a locus (pl.: loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. [1] Each chromosome carries many genes, with each gene occupying a different position or locus; in humans, the total number of protein-coding genes in a complete haploid set of 23 chromosomes is estimated at ...
During cell division, the identical copies (called a "sister chromatid pair") are joined at the region called the centromere (2). 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 ...
In humans, Robo1 and Robo2 are located on chromosome 3p12.3, while Robo3 and Robo4 are found on chromosome 11p24.2. In mice, the corresponding Robo genes 1 and 2 are found on chromosome 16 and Robo genes 3 and 4 are located on chromosome 9.
Often, the centromere has a three layered covering known as Kinetochore. Diagram of a duplicated and condensed eukaryotic chromosome. (1) Chromatid – one of the two identical parts of the chromosome after S phase. (2) Centromere – the point where the two chromatids touch, and where the microtubules attach. (3) Short arm (p).
The monocentric chromosome is a chromosome that has only one centromere in a chromosome and forms a narrow constriction. Monocentric centromeres are the most common structure on highly repetitive DNA in plants and animals. [11]
Deoxyribonuclease gamma (also termed DNase γ, deoxyribonuclease 1L3, DNASE1L3, of deoxyribonuclease I like 3) is an enzyme that in humans is encoded by the DNASE1L3 (also termed the deoxyribonuclease 1L3 or deoxyribonuclease 1 like 3) gene. This gene's is located on chromosome 3's "p arm", i.e., short arm, between region 1, band 4, sub-band 3 ...
