   What is a chromosome in biology?

   • Chromosomes are thin strands of DNA (deoxyribonucleic acid). The basic unit of genetic material inherited from our parents. A gene is a section of DNA which controls part of a cell's chemistry - particularly protein production. Genetic structures that usually occur in functional pairs in the nucleus of cells (except in gametes and bacteria).

   What is the difference between a chromosome and a gene?

   • Genes are short sections of DNA. DNA carries genetic code that determines characteristics of a living organism. Chromosomes are thin strands of DNA (deoxyribonucleic acid). The basic unit of genetic material inherited from our parents. A gene is a section of DNA which controls part of a cell's chemistry - particularly protein production.

   What are chromosomes made of?

   • Chromosomes are threadlike structure that carries DNA along with histone protein. Chromosomes are composed of DNA, and the primary chromosome function is to carry the essential genetic material of the cell, i.e., DNA holds all the genetic information encoded in DNA genes. Does this also clarify what are genes made of?

   Where are chromosomes located?

   • 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.

   How do chromosomes work in a cell?

   • 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. Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing.

   How many chromosomes are in a gene?

   • A gene is a section of DNA which controls part of a cell's chemistry - particularly protein production. Genetic structures that usually occur in functional pairs in the nucleus of cells (except in gametes and bacteria). Control centre of a cell containing genetic material. Humans have 46 chromosomes arranged in 23 pairs.

   Oct 4, 2019 · A chromosome is a string of DNA wrapped around associated proteins that give the connected nucleic acid bases a structure. During interphase of the cell cycle, the chromosome exists in a loose structure, so proteins can be translated from the DNA and the DNA can be replicated.

   A chromosome is a package of DNA with part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
