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. Fill the terms in gaps to correctly complete these sentences. Not all the terms will be used.
Terms: centromere(s), interphase, genosome(s), chromosome(s), sister chromatyd(s), cytokinesis, mitotic spindle(s), kinetochore(s), chromatin
1. DNA replication produces two identical DNA molecules, called ___________, which separate during mitosis.
2. After chromosomes condense, the ____________ is the region where the identical DNA molecules are most tightly attached to each other.
3. During mitosis, microtubules attach to chromosomes at the ____________.
4. In dividing cells, most of the cell’s growth occurs during ___________.
5. The ___________ is a cel structure consisting of microtubules, which forms during early mitosis and plays a role in cel division.
6. During interphase, most of the nucleus is filled with a complex of DNA and protein in a dispersed form called __________.
7. In most eukaryotes, division of the nucleus is followed by __________, when the rest of the cell divides.
8. The _____________ are the organizing centers for microtubules involved in separating chromosomes during mitosis.

Respuesta :
