Coagulase reacts with prothrombin in the blood. The resulting complex is called staphylothrombin, which enables the enzyme protease to convert fibrinogen, a plasma protein produced by the liver, to fibrin.
Chromosome diseases are genetic diseases where a large part of the genetic code has been disrupted. Chromosomes are long sequences of DNA that contain hundreds or thousands of genes.
Chromosomal abnormalities are common causes of birth defects that can affect the brain and other parts of the body. The normal fertilized egg cell contains 23 chromosomes from the mother and 23 from the father. Thus, there are normally 23 pairs of chromosomes in the fertilized egg. These include two sex chromosomes: XX for girls and XY for boys. Some chromosomal abnormalities occur when there is an extra chromosome. Here are a few examples of chromosomal abnormalities that can affect the functioning of the brain.
