Mitosis and cell cycle terminology

As in most areas of biology, the study of mitosis and the cell cycle involves a lot of new terminology. Knowing what the different terms mean is essential to understanding and describing the processes occurring in the cell.

Drag the terms on the left to correctly complete these sentences. Not all the terms will be used.

Answer 1

1. DNA replication produces two identical DNA molecules, called sister chromatid(s) which separate during mitosis.

2. After chromosomes condense, the centromere(s) is the region where the identical DNA molecules are most tightly attached to each other.

3. During mitosis, microtubules attach to chromosomes at the kinetochore(s).

4. Ir dividing cells, most of the cell's growth occurs during Interphase

5. The mitotic spindle(s) is a cell structure consisting of microtubules, which forms during early mitusis and plays a rule in cell division.

6. During interphase, most of the nucleus is filled with a complex of DNA and protein in a dispersed form called

7. Ir most eukaryotes, division of the nusleus is followed by cytokinesis when the rest of the cell divides.

8. The centrosome(s) are the organizing centers for microtubules involved in separating chromosomes during mitosis.
