Chromosome - Wikipedia
A chromosome is a deoxyribonucleic acid molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle. Chromosomes ...
What is a chromosome? - Genetics Home Reference - NIH
The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.
chromosome | Structure & Function | Britannica.com
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. For instance, the 46 chromosomes found in human cells have a combined length of 200 nm (1 nm = 10 − 9 metre); if the chromosomes were to be unraveled, the genetic material they contain would measure roughly 2 metres (about 6 ...

The chromatin loops are then wrapped around each other to make a full chromosome. Each chromosome has two short arms (p arms), two longer arms (q arms), and a centromere holding it all together at the centre. Humans have 23 pairs of chromosomes (46 in total): one set comes from your mother and one set comes from your father.

The term chromosome is derived from the Greek words "chroma" or color and "some" or body and is so named because chromosomes have the ability to be stained with dyes.
Chromosome 1 - Wikipedia
Chromosome 1 is the designation for the largest human chromosome.Humans have two copies of chromosome 1, as they do with all of the autosomes, which are the non-sex chromosomes.Chromosome 1 spans about 249 million nucleotide base pairs, which are the basic units of information for DNA. It represents about 8% of the total DNA in human cells.

Our genetic information is stored in 23 pairs of chromosomes that vary widely in size and shape. Chromosome 1 is the largest and is over three times bigger than chromosome 22. The 23rd pair of chromosomes are two special chromosomes, X and Y, that determine our sex. Females have a pair of X chromosomes (46, XX), whereas males have one X and one Y chromosomes (46, XY).
