What is chromatin material and how does it change before cell division Class 9?

What is chromatin material and how does it change before cell division?

The DNA + histone = chromatin

As the cell initiates divisions by either meiosis or mitosis. During the interfaces, DNA is combined with the proteins and organized into a structure called chromatin. This chromatin is a thread like structure which condenses to form chromosomes just before the cell division occurs.

How does the chromatin changes during cell division?

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. … During cell division, the structure of the chromatin and chromosomes are visible under a light microscope, and they change in shape as the DNA is duplicated and separated into two cells.

What is chromatin Fibre Class 9?

Chromatin is located in the nucleus of our cell. It is composed of DNA and proteins that condense to form chromosomes. It compresses the DNA structure into a compact unit so that it can fit within the nucleus. The nucleosome further folds to form a chromatin fibre. …

Where are chromosomes located what is chromatin material and how does it change during cell division?

Answer Expert Verified

Chromosomes are located inside the nucleus of plants and animals cells. Chromosomes are composed of single DNA(Deoxyribo Nucleic Acid) molecule and proteins. Chromatin material is thread like strucure that condenses to form x shaped chromosomes during cell division.

What happens to chromatin during cell division Class 9?

In the nucleus, there is usually genetic material that is present. At the start of cell division, that is prophase, this chromatin material starts to condense and form chromosomes. … Thus in this manner, the genetic material gets divided into two separate cells. Telophase: After anaphase is done, the telophase occurs.

What happens to chromatin during prophase and metaphase of mitosis?

During prophase, the nucleus disappears, spindle fibers form, and DNA condenses into chromosomes ( sister chromatids ). During metaphase, the sister chromatids align along the equator of the cell by attaching their centromeres to the spindle fibers.
