daughter chromosome

A new nuclear membrane forms around the separated daughter chromosomes.

Corresponding daughter chromosomes attach at opposite ends of the cell.

Although when mitosis is occurring the daughter chromosomes are carrying exactly the same genetic make up.

Over time this would result in progressive shortening of one of the daughter chromosomes.

As the cell elongates, corresponding daughter chromosomes are pulled toward opposite ends.

The centromeres are split, and the new daughter chromosomes are pulled toward the poles.

The daughter chromosomes will assemble centromeres in the same place as the parent chromosome, independent of sequence.

As a matter of convention, each sister chromatid is now considered a chromosome, so they are renamed to daughter chromosomes.

In closed mitosis, the daughter chromosomes migrate to opposite poles of the nucleus, which then divides in two.

The physical strength of chromatin is vital for this stage of division to prevent shear damage to the DNA as the daughter chromosomes are separated.

One of the most essential topological problem occurs at the very end of replication, when daughter chromosomes must be fully disentangled before mitosis occurs.

Cell division is controlled in a cell cycle; after the cell's chromosome is replicated and the two daughter chromosomes separate, the cell divides.

These sister chromatids now become separate daughter chromosomes, and are pulled apart by shortening kinetochore microtubules and move toward the respective centrosomes to which they are attached.

In the endocycle (endomitosis or endoreduplication) chromosomes in a 'resting' nucleus undergo reduplication, the daughter chromosomes separating from each other inside an intact nuclear membrane.

A new nuclear membrane, using the membrane vesicles of the parent cell's old nuclear membrane, forms around each set of separated daughter chromosomes (though the membrane does not enclose the centrosomes) The nucleoli reappear, too.

In the examples above, the emergence of the genetic code and the emergence of chromosomes that duplicate and partition daughter chromosomes into two daughter cells, the evolution of controlled recombination, seem to become instantiated as "biological laws," even though they are entirely historically contingent.
