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.
1. DNA replication produces twc identical DNA molecules, called, which separate during mitosis.
2. After chromosomes condense, theis tie 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. Theis a cell structure consisting of microtubules, which forms during early mitosis 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. In most eukaryotes, division of the nucleus is followed by, when the rest of the cell divides.
8. Theare the organizing centers for microtubules involved in separating chromosomes during mitosis.

Explanation:

DNA replication produces two identical DNA molecules which are known or called as sister chromatids, by cell division each sister chromatid is  separated. The region on chromosome known as  centromere, by which they are most tightly attached to each other.

During cell division, micro-tubules attach to chromosomes at the region on chromosome knwon as  kinetochore. In replicating or dividing cells, most of the growth like DNA replication and other type of growth also  occurs during inter-phase.The mitotic spindle: consisting of micro-tubules, which plays  role in cell division.

During inter-phase, DNA is in unfolded state and is called or known  as chromatin.

The division of cytoplasm which occurs after karyokinesis is known or called as cytokinesis.

The centrosomes is  the organizing centers for microtubules, and these  microtubules  works in the separation of chromosomes during cell division.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
