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 .
Metaphase: In this stage the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere. Anaphase: In this stage the sister chromatids separate into individual chromosomes and are pulled apart. Telophase & cytokinesis: Chromosomes decondense and are surrounded by a newly formed nuclear ...
The centromeres of the chromosomes convene themselves on the metaphase plate, an imaginary line that is equidistant from the two spindle poles. [3] This even alignment is due to the counterbalance of the pulling powers generated by the opposing kinetochore microtubules, [ 4 ] analogous to a tug-of-war between two people of equal strength ...
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 ...
Schematic karyogram of the human chromosomes, showing their usual state in the G 0 and G 1 phase of the cell cycle. At top center it also shows the chromosome 3 pair after having undergone DNA synthesis, occurring in the S phase (annotated as S) of the cell cycle. This interval includes the G 2 phase and metaphase (annotated as "Meta.").

Schematic karyogram of the human chromosomes, showing their usual state in the G 0 and G 1 phase of the cell cycle. At top center it also shows the chromosome 3 pair in metaphase (annotated as "Meta."), which takes place after having undergone DNA synthesis which occurs in the S phase (annotated as S) of the cell cycle.
