A chromosome is an organized package of dna found in the nucleus of the cell different organisms have different numbers of chromosomes humans have 23 pairs of chromosomes--22 pairs of numbered chromosomes, called autosomes, and one pair of sex chromosomes, x and y. X chromosome the x chromosome is home to several immune-related genes including tlr7, tlr8, foxp3 gene, cd40, il-1, iκb kinase γ, and cytokine receptors (il9r), to name a few (dai and ahmed, 2014 van lunzen and altfeld, 2014.

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. Chromosome mapping is the ultimate puzzle did you know you can use your dna test results to find out which ancestors gave you specific segments of our dna. A chromosome is a dna molecule with part or all of the genetic material (genome) of an organism most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins.

Chromosome 18q- syndrome is a chromosomal disorder in which there is deletion (monosomy) of part of the long arm (q) of chromosome 18 chromosomes are found in the nucleus of all body cells. A chromosome is called this if it is large enough to see with a light microscope using stains or florescent probes to highlight missing, extra, or moved genetic material.
A chromosome is a strand of dna that is encoded with genes the word chromosome was originally coined in german from the greek words khroma, meaning color, and soma meaning body. 19th century: from german chromosom, ultimately from ancient greek χρῶμα (khrôma, colour) + σῶμα (sôma, body) (because they are stained under the microscope) (uk) ipa(key): /ˈkɹəʊməˌsəʊm. The y chromosome is one of two sex chromosomes in mammals, including humans, and many other animalsthe other is the x chromosomey is the sex-determining chromosome in many species, since it is the presence or absence of y that determines the male or female sex of offspring produced in sexual reproduction. Chromosomes are made up of dna segments chromosomes carry all the information that help a cell grows, survive and reproduce dna segments with specific patterns are called genes. Chromosome analysis or karyotyping is a test that evaluates the number and structure of a person's chromosomes in order to detect abnormalities a karyotype may be used to diagnose genetic diseases, some birth defects, such as down syndrome, or leukemia and lymphoma.
Chromosome: a carrier of genetic information that is visible under an ordinary light microscope each human chromosome has two arms, the p (short) arm and the q (long) arm. A structure in all living cells that carries the genes that determine heredity in all cells except bacterial cells, the chromosomes are thread-like strands of dna and protein that are contained in the nucleus.
