The function of mitosis and cytokinesis is

The function of mitosis and cytokinesis is

to distribute the cell’s DNA equally between the daughter cells

to divide the cytoplasm equally between the daughter cells

to distribute the parent cell’s organelles evenly

all of the above

The chromosomes of daughter cells formed during mitosis

are identical to the chromosomes of the other daughter cell

both skin and heart muscle cells

Two DNA molecules, joined at the centromere, have coiled to form tiny bodies. This connected pair of DNA molecules is called a

chromosome

Two DNA molecules, joined at the centromere, have coiled to form tiny bodies. Each individual DNA molecule in this connected pair of DNA molecules is called a
