Chromosome - Wikipedia
A chromosome is a package of DNA containing 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.

Chromosomes: Definition, Structure & Function
Having two copies of each chromosome ensures that you get the right amount of proteins made by the genes on those chromosomes. This system can also protect you from some diseases.

Chromosome | Structure & Function | Britannica
chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness.

Functions and Types of Chromosomes - GeeksforGeeks
One chromosome in each pair is inherited from the mother and the other from the father. The 22 pairs of chromosomes are called autosomes, and the 23rd pair is called the sex or allosome chromosome.

Chromosomes Fact Sheet - National Human Genome Research Institute
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. The term chromosome comes from the Greek words for color (chroma) and body (soma).

XX and XY Chromosomes: Biological Sex and Genetic Differences
While the X chromosome has about 900 genes, the Y chromosome only has about 100 – the lowest out of all 46 chromosomes. Like the X chromosome, you can lose part of the Y chromosome as you...

Chromosome - National Human Genome Research Institute
The human X chromosome is about three times larger than the human Y chromosome, containing about 900 genes, while the Y chromosome has about 55 genes. The unique structure of chromosomes keeps DNA tightly wound around spool-like proteins, called histones.

What is a chromosome and how many do humans have? - YourGenome
A chromosome is a tightly wound bundle of DNA. It’s the way DNA is packaged in animal and plant cells – contrasting with bacteria where DNA floats freely around the cell.

Chromosome - Simple English Wikipedia, the free encyclopedia
The mother's eggs always contain an X chromosome, while the father's sperm contains either a Y chromosome or an X chromosome. That determines the sex of the child.

Chromosomes- Definition, Structure, Types, Model, Functions
Each chromosome is made up of DNA tightly coiled many times around proteins that support its structure. The proteins that bind to the DNA to form eukaryotic chromosomes are traditionally divided into two classes: the histones and the non-histone chromosomal proteins.
