Hemophilia is caused by a defect in the genes responsible for the formation of blood clotting factors viii and ix. These genes are located on the X chromosome. A female has two X chromosomes and a male has an X chromosome and a Y chromosome. Therefore, all the daughters of a hemophiliac father will be the carriers of this disease, and half of his sons acquiring the X chromosome from the father will have the disease.
The original nucleus is known as the <em>parent nucleus</em>, and the core staying after the rot is known as the daughter nucleus
If a core radiates an alpha molecule, it loses two protons and daughternucleus in this way, the little girl core has a nuclear mass of 4 less and a nuclear number of 2 not exactly the parent core
In β-decay, a neutron is changed over into a<em> proton, electron, and electron-anti neutrino</em>
Which builds the nuclear number of the nuclide by 1. <em>For 211Pb, this would bring about a nuclide of 211Bi.</em>
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
