What are chromosomes and chromatin material Class 9?

Chromatin is a complex formed by histones packaging the DNA double helix. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are composed of condensed chromatin fibers.

What are chromosomes and chromatin material?

Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes. The way in which eukaryotes compact and arrange their chromatin not only allows a large amount of DNA to fit in a small space, but it also helps regulate gene expression.

What is chromatin material Class 9?

Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. This is Class 9.

What are chromosomes according to class 9?

They are called chromosome. They are formed when the chromatin condenses together when the cell is about to divide. Chromosomes contain DNA and nuclear proteins. They contain the hereditary information for inheritance of features from the parents to the offspring as DNA.

What is the major difference between chromatin and chromosomes?

Chromatin is a complex formed by histones packaging the DNA double helix. Chromosomes are structures of proteins and nucleic acids found in the living cells and carry genetic material. Chromatin is composed of nucleosomes. Chromosomes are composed of condensed chromatin fibers.

What is the function of chromatin Class 9?

Chromatin fibers are coiled and condensed to form chromosomes. Chromatin makes it possible for a number of cell processes to occur including DNA replication, transcription, DNA repair, genetic recombination, and cell division. People often confuse these three terms: chromatin, chromosome, and chromatid.

What is Nucleoid in biology class 9?

Nucleoid is the undefined nuclear region containing only nucleic acids, in the prokaryotic cells. … It transports the material in and out of the cell. It is also reponsible for the formation of lysosomes.
