How do you describe 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.

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.

How many chromosome are there?
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.
What are chromosomes made of *?
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.
