Rh factor is a protein on the surface of red blood
corpuscles in many persons.It was discovered in 1940 by
Landsteiner and Wiener in the blood of rhesus monkey, hence
its name. Majority(85 to 99%)of the people have this factor
and are classified as Rh positive(Rh+). Others who lack
this factor are classified as Rh negative(Rh-).Formation of
this protein is controlled by a dominant gene designated
as R. Thus RR (homogyous dominant)and Rr(heterogyous
dominant)persons are Rh positive,and rr (homogyous
recessive)persons are Rh negative. Both the individuals are
phenotypically normal. The trouble arises when the blodd of
thetwo mixes up or during pregnancy

why dna has no uricel while rna had?
A blastomere was removed from an 8-cell human embryo, and its beta-globin gene was amplified by PCR. The beta-globin DNA was treated with an enzyme that cuts on either side of and within the normal allele (producing a small fragment), but not within the sickle cell allele (producing a large fragment). Electrophoresis of the treated DNA from the blastomere demonstrated the presence of both a large and small fragment derived from the beta-globin genes. How should you interpret this test?
