The X chromosome is one of the two sex chromosomes in humans (the other is the Y chromosome). The sex chromosomes form one of the 23 pairs of human chromosomes in each cell. The X chromosome spans about 155 million DNA building blocks (base pairs) and represents approximately 5 percent of the total DNA in cells.In humans and other mammals a sex chromosome, two of which are normally present in female cells (designated XX) and only one in male cells (designated XY).
Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. The X chromosome likely contains 800 to 900 genes that provide instructions for making proteins. These proteins perform a variety of different roles in the body.
PS:The above content is from google ,I am not getting any words or ideas for the last few alphabets so the last few post’s will be like this only.
PS:I am not a doctor, these are just my findings, my experiences and my infertility warrior friends experiences,which are a part of my life. I am half doctor myself because we go though so much,sometimes I feel I know my diagnosis better than my RE(Reproductive Endocrinologist). Hope these posts make some sense for people who are not a part of this journey.This post is a part of #AtoZchallenge2018.
