what is chromosome? what is the structure of chromosomes ?
Answers
A carrier of genetic information that is visible under an ordinary light microscope. Each human chromosome has two arms, the (short) arm and the (long)arm.A chromosome contains roughly equal parts of protein and DNA.
Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Chromosomes are not visible in the cell's nucleus—not even under a microscope—when the cell is not dividing.
Explanation:
chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging
proteins called histones which, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity.

the structure 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.
