Na espécie humana ocorrem quatro grupos sanguíneos do sistema ABO – A, B, AB e 0 (zero) –, relacionados à presença de certos antígenos na membrana dos glóbulos vermelhos. A genealogia adiante revela grupos sanguíneos do sistema ABO. A análise da genealogia sugere que a) o indivíduo II-2 pertence ao grupo sanguíneo A.

b) a probabilidade de o indivíduo II-4 ser do grupo 0 (zero) é 100%.

c) o indivíduo II-1 não apresenta os aglutinogênios A nem B, antígenos que são glicoproteínas.

d) o alelo IA é dominante em relação ao alelo IB e os indivíduos ii não possuem as aglutininas anti-A e anti-B.

e) o casal I-1 x I-2 pode vir a ter filhos dos quatro grupos sanguíneos do sistema ABO.

this protocol provides a detailed procedure for agarose-based ip to purify and enrich the protein of interest.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
