Frequent question: What is the chemical nature and function of chromosomes?

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). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

What is the nature of chromosomes?

Chromosomes are cellular structures that contain the genetic material. A chromosome is comprised of a single DNA molecule that may be either circular or linear. The full complement of a cell’s chromosomes is called the genome.

What are the function of chromosomes?

Functions 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 is the chemical in chromosomes?

The major chemical components of the chromosome are DNA, RNA (nucleic acids), and proteins (histones and nonhistones).

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 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 are chromosomes write its two functions?

They are composed of DNA and Proteins. (i) Chromosomes contain hereditary information of the cell. (ii) DNA of chromosomes also controls all the activites of the cell.

What is the function of chromosomes class 9th?

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 are chromosomes made of?

A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.

What is chemical composition?

Chemical composition is the arrangement, type, and ratio of atoms in molecules of chemical substances. Chemical composition varies when chemicals are added or subtracted from a substance, when the ratio of substances changes, or when other chemical changes occur in chemicals. Chemical formulas show this information.

What is chemical composition of gene?

Genes are composed of deoxyribonucleic acid (DNA), except in some viruses, which have genes consisting of a closely related compound called ribonucleic acid (RNA). A DNA molecule is composed of two chains of nucleotides that wind about each other to resemble a twisted ladder.

What two chemical compounds make up a chromosome?

However, as early as the 1920s, scientists agreed that chromosomes were made of two chemical substances-deoxyribonucleic acid (DNA) and protein.
