(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.
What are chromosomes class 10th?
A chromosome is a DNA molecule that consists of a part or all of the genetic material of an organism. The chromosome is present in the nucleus of each cell, and it is packaged into thread-like structures.
What is the role of chromosomes in the process of reproduction?
The main function of chromosomes is to carry the DNA and transfer the genetic information from parents to offspring. Chromosomes play an important role during cell division. They protect the DNA from getting tangled and damaged.
What is the process of sexually reproducing organisms?
Sexual reproduction begins with sperm and egg cells, which are produced through a process called meiosis. These cells are referred to as haploid because they contain half of the number of chromosomes as the parent.
What are chromosomes made up of Class 9?
Each chromosome is made up of two components (i) Deoxyribonucleic acid (DNA) (ii) Proteins (e.g.; his tones and acidic proteins) These consist of two (unreplicated) or four (duplicated) arms and a primary constriction or centromere which gives them a particular shape due to its position.
What are chromosomes and how are they formed?
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

What do you mean by chromosomes Class 8?
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 is chromosome and its function Class 8?
Chromosomes are found in the nucleus of a cell. Function:
Chromosomes carry genes and help to transfer characters from the parents to the offspring
What is chromosome Toppr?
Chromosomes are the condensed form of chromatin present in the nucleus of the cells. These are made up of DNA and histone proteins (called nucleosomes) but the degree of condensation is much more than that of chromatin. Chromosomes usually appear during the time of cell division.
What is meant by chromosome explain its types Class 9?
Answer: Chromosomes are
basic building blocks of life that carry all of the information used to help a cell grow, thrive and reproduce
. Chromosomes are made up of DNA. There are four types of chromosomes- metacentric, sub-metacentric, acrocentric and telocentric chromosomes.
What are chromosomes write its function Class 9?
The main function of chromosomes is to carry the genetic material from one generation to another. Chromosomes play an important role and act as a guiding force in the growth, reproduction, repair and regeneration process, which is important for survival. Chromosomes protect the DNA from getting tangled and damaged.
What is the role of chromosomes in the process of reproduction Class 10?
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 chromosomes made up of Brainly?
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). … Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA).
How do you say chromosome?
Break ‘chromosome’ down into sounds:
[KROH] + [MUH] + [SOHM]
– say it out loud and exaggerate the sounds until you can consistently produce them.
What are chromosomes and genes?
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 are chromosomes Brainly in?
Answer. a thread like structure found in the nuclei of most living cells is called chromosomes.it carries genetic information in the form of genes.
What is chromosome in human body?
structures found in the center (nucleus) of cells that carry long pieces of DNA
. DNA is the material that holds genes. It is the building block of the human body. Chromosomes also contain proteins that help DNA exist in the proper form.
Where do the chromosomes come from?
Chromosomes come in matching pairs, one pair from each parent. Humans, for example, have a total of 46 chromosomes, 23 from the mother and another 23 from the father. With two sets of chromosomes, children inherit two copies of each gene, one from each parent.
What is the function of chromosomes Brainly?
Answer: 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.

What is chromosome shaala?
Solution. Chromosomes are highly condensed coiled chromatic fibres made of DNA which carries the hereditary material of the organisms.
What are types of chromosomes?
Among many organisms that have separate sexes, there are two basic types of chromosomes: sex chromosomes and autosomes. Autosomes control the inheritance of all the characteristics except the sex-linked ones, which are controlled by the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes.
