a thread like structure of nucleic acids and proteins found in most of the living cells, carrying genetic information in the form of genes.
What are chromosomes Class 9?
Chromosomes contain DNA and nuclear proteins. They contain the hereditary information for inheritance of features from the parents to the offspring as DNA. The DNA molecules contain the information for construction and organization of cells.
What do you mean by chromosome?
(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes.
What is chromosome 10 CBSE?
Answer: Chromosomes are the condensed chromatin material inside the nucleus, during cell division. Chromosomes consist of DNA, histone proteins, non-histone proteins, metallic ions and also some RNA.
What is chromosome by Vedantu?
A chromosome can be defined as an entire chain of DNA and it comes along with a group of stabilizing proteins. Chromosomes seem to be thread-like in appearance and are located inside the nucleus of an animal and plant cells. As discussed above, each chromosome is made up of protein and DNA (a single molecule).
What are the 4 types of chromosomes?
On the basis of the location of the centromere, chromosomes are classified into four types: metacentric, submetacentric, acrocentric, and telocentric.
What are the 4 parts of a chromosome?

What is a chromosome example?
The definition of a chromosome is a thread-like structure of DNA (nucleic acids and proteins) that carries genes. … The “X” or “Y” gene that determines whether you will be a boy or a girl is an example of a chromosome.
What is the basic function of chromosomes?
The most important function of chromosomes is to carry the basic genetic material – DNA. DNA provides genetic information for various cellular functions. These functions are essential for growth, survival, and reproduction of the organisms. Histones and other proteins cover the Chromosomes.
What are the components of chromosome?
The major chemical components of the chromosome are DNA, RNA (nucleic acids), and proteins (histones and nonhistones).
