- Chromosomes: Definition, Structure Function - Cleveland Clinic
Chromosomes are long strings of DNA wrapped around proteins to make them compact They’re a way for cells to organize and store your DNA Humans typically have 23 pairs of chromosomes for a total of 46 chromosomes The first 22 are called autosomes and the last pair are sex chromosomes
- Chromosomes Fact Sheet - National Human Genome Research Institute
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
- 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
- Chromosome - Definition, Function Structure - Biology Dictionary
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 During mitosis and meiosis, the chromosome becomes condensed, to be organized and separated

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 and how many do humans have? - YourGenome
Chromosomes are tightly coiled bundles of DNA found in the nucleus of almost every cell in our body In plant and animal cells, DNA is tightly packaged into thread-like structures called chromosomes Humans have 23 pairs of chromosomes Other living things have a different number of chromosomes
- What is a chromosome?: MedlinePlus Genetics
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
- What are Chromosomes? - University of Utah
This DNA is distributed among 23 chromosomes, of which we have two sets We inherit one set from each parent Each chromosome includes a single, linear molecule of DNA with its own set of genes Chromosomes are numbered according to their size, and genes are arranged along them in a specific order
