Rearrangements of the Blood Group RhD Gene
Rearrangements of the Blood Group RhD Gene

... HE RhD ANTIGEN is the major antigen of the RH blood group system. Its presence or its absence at the human red blood cell(RBC) surface determine the Rh-positive (85% of Caucasians) and Rh-negative (1 5% of Caucasians) phenotypes, respectively. However, both types of cells carry antigens of the C/c a ...

X-inactivation



X-inactivation (also called lyonization) is a process by which one of the two copies of the X chromosome present in female mammals is inactivated. The inactive X chromosome is silenced by its being packaged in such a way that it has a transcriptionally inactive structure called heterochromatin. As nearly all female mammals have two X chromosomes, X-inactivation prevents them from having twice as many X chromosome gene products as males, who only possess a single copy of the X chromosome (see dosage compensation). The choice of which X chromosome will be inactivated is random in placental mammals such as humans, but once an X chromosome is inactivated it will remain inactive throughout the lifetime of the cell and its descendants in the organism. Unlike the random X-inactivation in placental mammals, inactivation in marsupials applies exclusively to the paternally derived X chromosome.
