The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

However, there is some evidence that the Y chromosome is being phased out of the evolutionary pipeline, and could one day disappear altogether — potentially giving rise to a new sex gene in the ...

The cell's nucleus contains chromosomes. These are long threads of DNA, which are made up of many genes. Humans have around 25,000 genes across their 23 pairs of chromosomes.

Conventional investigations of the genetic contributors to Alzheimer's disease (AD) risk and progression have ignored the role of the X-chromosome, primarily due to technical analysis limitations.

However, to precisely design sophisticated genetic circuits, interference between biological parts must be minimized, and encoding density must be increased for efficient gene circuit integration.

Large and rare duplications and deletions in a chromosome region known as 22q11.2 , which involves genes that regulate cardiac development, are linked to nonsyndromic bicuspid aortic valve disease.

30.3% (including 43.2% of cases with marker or ring chromosomes) had normal array results, suggesting either variation involving only heterochromatic (gene-poor) material or misinterpretation of ...
