Answer:
they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes
Explanation:
G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.
Answer:
A - 1/4
B - 1/2
C- 1/8
Explanation:
The complete question is
Diane has type A blood and Darryl has type B. They have a son Duane with type A blood and a daughter, Dora, with type B blood. If they have another child, what are the chances that it
A. Will have type AB blood?
B. Will be a girl?
C. Will be a boy with type O blood?
A.
Let the genotype of Diane be AO
Daryl can have genotype BO
AO * BO
AB, AO, BO, OO
Probability of having AB blood group is 1/4
B.
1/2
C
1/2 * 1/4 = 1/8
