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 - Cleveland Clinic
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.

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).

23 Chromosomes - Functions and Types of Chromosomes
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.

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 | 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.

What is a Chromosome? Structure, Function, and Role in Genetics
A single human chromosome can carry hundreds or even thousands of genes, which are the instructions for making proteins—molecules that perform virtually all tasks in a cell, from catalyzing reactions to providing structure. Each gene occupies a specific location, or locus, on a chromosome.

What is a chromosome?: MedlinePlus Genetics
What is a chromosome? 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.

Genes and Chromosomes - Fundamentals - MSD Manual Consumer ...
Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene. Some traits are caused by mutated genes that are inherited or that are the result of a new ...

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.
