In people, DNA, which encodes the all-inclusive strategy for our bodies, is composed as 23 sets of chromosomes. One sets, the sex chromosomes, comprises of either two X chromosomes (XX), bringing about a young lady, or one X and one Y chromosome (XY), bringing about a kid. The other 22 sets of chromosomes, alluded to as the autosomes, are numbered 1 through 22. While a portion of the DNA code can shift between people, the general appearance of every chromosome is remarkable when seen under a magnifying lens with recoloring. Every chromosome is composed into a few sections: a short arm (not introduce for a few chromosomes), a focal bit called the centromere, and a long arm. The arms contain the DNA arrangements that encode the qualities. The long arm is called by the quantity of the autosome and "q". Accordingly, the long arm of chromosome 22 is called 22q. Chromosomal arms likewise have areas that show up as light or dim groups after unique recoloring, which are numbered. Hence, 22q11 alludes to the 11 band (proclaimed one-one) on the long arm of chromosome 22.
