Chromatin network and chromosomes indicate the same network of genetic material. The genetic material of the cell which is the chromatin network becomes more prominent and visible at the stage of cell division. This modification is termed as chromosomes.
What is the relationship between chromatin network chromosomes and chromatids?
Chromatin, Chromosomes and Chromatids
The chromatin undergoes further condensation to form the chromosome. So the chromatin is a lower order of DNA organization, while chromosomes are the higher order of DNA organization. Chromosomes are single-stranded groupings of condensed chromatin.
What is the difference between chromatin network and chromosome?
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.
(i) On cell division, chromatin network organise themselves into chromosomes. (ii) Chloroplast is a plastid which contains a green pigment called chlorophyll which is responsible for photosynthesis. (iii) The segments of DNA are called genes.
Chromatin is DNA packaged by histones. When chromatin is condensed and further organized, we have chromosomes . Chromosomes are paired whereas chromatin is not.
How are chromatin, chromatid and chromosomes related to each other? Answer: Inside the nucleoplasm a tangled mass of thread-like structures is called chromatin. … When a cell starts to divide, the tangled mass of chromatin condense into long threads and finally rod-like bodies called chromosomes.
How are chromosomes formed from chromatin?
The cellular DNA is replicated during interphase, resulting in the formation of two copies of each chromosome prior to the beginning of mitosis. As the cell enters mitosis, chromatin condensation leads to the formation of metaphase chromosomes consisting of two identical sister chromatids.
What is the difference between chromosome and chromatin Class 9?
Answer: Chromatin is the DNA fibers which are scattered all over inside the nucleus in the interphase of mitosis. Whereas chromosome is a highly condensed chromatin or DNA fiber which is seen just prior to a cell division, be it mitosis or meiosis.
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person’s genes. Genes are contained in chromosomes, which are in the cell nucleus.
What is chromatin network?
The chromatin is the network of the cell nucleus, which contains all the DNA of the nucleus of the cell. The DNA in the nucleus is packaged by the histone proteins histones. The protein and DNA complex is called chromatin.
What are the chromosomes?
(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.
