Admin What does telophase look like in a cell?
When you look at a cell in telophase under a microscope, you will see the DNA at either pole. It may still be in its condensed state or thinning out. The new nucleoli may be visible, and you will note a cell membrane (or cell wall) between the two daughter cells.
Is chromatin made of DNA?
Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell’s genetic instructions. The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus.
What happens when an animal cell goes through cytokinesis?
During cytokinesis, the cytoplasm splits in two and the cell divides. The process is different in plant and animal cells, as you can see in Figure 7.3. 8. In animal cells, the plasma membrane of the parent cell pinches inward along the cell’s equator until two daughter cells form.
Are chromosomes visible in telophase?
In prophase, the nucleolus disappears and chromosomes condense and become visible. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes. Finally, in cytokenesis, the two daughter cells are separated.
What happens in telophase 1?
Telophase I. At each pole, during this stage, there is a complete haploid set of chromosomes (but each chromosome still has two sister chromatids). A cleavage furrow appears, and by the end of this stage the parent cell has divided into two daughter cells.
What does Telo mean in biology?
Compare mitotic telophase >> Etymology:The prefix telo-is from the Greek word telos, meaning end or completion, which in the present case refers to the end or completion of meiosis I. Some other common bio terms starting with this prefix are: telocentric chromosome, telomerase, and telomere.
Why do fungi still go through telophase?
The fungi still go through telophase, as the nucleolus must still break down and the DNA must condense and subsequently unwind during telophase. The spindle fibers must also be broken back down into monomers, so the cells can resume their normal functions.
What is the role of spindle depolymerization during telophase?
Spindle depolymerization during telophase occurs from the plus end and is, in this way, a reversal of spindle assembly. Subsequent microtubule array assembly is, unlike that of the polarized spindle, interpolar. This is especially apparent in animal cells which must immediately, following mitotic spindle disassembly,…
