chromosomes, plural;
  1. A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes

  1. a threadlike strand of DNA in the cell nucleus that carries the genes in a linear order; "humans have 22 chromosome pairs plus two sex chromosomes"
  2. (chromosomal) of or relating to a chromosome; "chromosomal defect"
  3. A chromosome is an organized building of DNA and protein that is found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions. ...
  4. In genetic algorithms, a chromosome (also sometimes called a genome) is a set of parameters which define a proposed solution to the problem that the genetic algorithm is trying to solve. ...
  5. A structure in the cell nucleus that contains DNA, histone protein, and other structural proteins
  6. (Chromosomes) Organised structures of DNA and proteins found in cells.
  7. (Chromosomes) structures found in the nucleus of a cell that contain the genes. Chromosomes come in pairs, and a normal human cell contains 46 chromosomes, 22 pairs of autosomes and two sex chromosomes.
  8. (chromosomes) (KROH-muh-sohms): threadlike structures in the cell that carries genes
  9. (Chromosomes) A threadlike linear strand of DNA and associated proteins in the nucleus of cells that carries the genes and functions in the transmission of hereditary information.
  10. (Chromosomes) Structure in the nucleus of the cell containing all the genes.
  11. (chromosomes) filaments of genetic material in every cell nucleus that are made up of genes and that transmit genetic information from one generation of cells to the next.
  12. (Chromosomes) Rod-shaped bodies in a cell's nucleus which carry the genes that convey hereditary characteristics. Made up of DNA.
  13. (chromosomes) Structures in the nucleus of a eukaryotic cell that consist of DNA molecules that contain the genes. PICTURE
  14. (CHROMOSOMES) in eukaryotes, usually elongated structures in the nucleus along which the genes are located; actually long DNA molecules with associated protein; seen as several to many threads or rods which appear in contracted form during mitosis and meiosis. ...
  15. (Chromosomes) Structures made up of strands of DNA molecules and associated proteins and containing the genes that define a person's bodily makeup (e.g., hair and eye color, disease expression, etc.). Every cell in the body contains an identical set of 46 chromosomes, grouped into 23 pairs.
  16. (Chromosomes) The thread-like structures within the nuclei of cells comprised of DNA. Deoxyribonucleic acid or DNA carries genetic information involved in directing cellular activities, thus controlling bodily growth and functioning and determining the expression of inherited traits. ...
  17. (Chromosomes) Threadlike structures in animal or plant nuclei, seen during karyolinesis (nuclear division characteristic of mitosis) that carry the linearly arranged genetic material.
  18. (Chromosomes) are compact packages of DNA contained within single cells. Unraveled, the ultra-thin strands of DNA from a single human cell are about 3 meters long. ...
  19. (Chromosomes) double stranded DNA helixes.
  20. (chromosomes) (in  heredity (genetics): Simple linkage)
  21. (chromosomes) Bundles of DNA that vary in size, shape, and function. They are most visible when cells divide.
  22. (chromosomes) DNAmolecules that contain the set of instructions required to build and maintain cells.
  23. (chromosomes) distinct bodies in the nucleus containing DNA that appears during cell division and contain genes; in bacteria, a long circular strand of DNA in the cell
  24. (chromosomes) one of the threadlike structures consisting of chromatin and carrying genetic information arranged in a linear sequence. (D)
  25. (chromosomes) those entities in the body's cells that contain the genes. They are rodlike bodies which can be seen only under the microscope. They determine everything about us: how tall we are, our hair and eye color, etc.
