CC&M+Metaphase

CC&M = METAPHASE = = Metaphase is the second stage of mitosis. The duplicated chromosomes are lined up between the poles of the mitotic spindle. = During this phase, the mitotic spindle is fully formed with its poles at the opposite ends of the cell. The chromosomes come together on the metaphase plate, which is an imaginary plane equidistant between the two poles of the spindle.

The centromeres of all the chromosomes are lined up on the metaphase plate. For each chromosome, the kinetochores of the two sister chromatids face opposite poles of the spindle. The microtubes attatched to a specific chromatid all come from one pole of the spindle, and those attatched to its sister chromatid come from the opposite poles. = ﻿ = =﻿ =
