The best answer is "C"
Dominant negative
Explanation:
Dominant negative represents a class of mutation in which a mutant receptor interferes with the function of the wild-type version of the receptor.
null/amorphic: It is a form of mutation that causes the complete loss of Gene function (protein) by disrupting translation and/or preventing transcription.
Neomorphic: Describes a mutation where altered gene product possesses a completely new molecular function and sometimes pattern of gene expression.
Hypmorphic: describes a mutation that causes a partial loss of gene function usually through reduced (protein, RNA) expression or reduced functional performance.
hypermorphic: describes a mutation that causes an increase in the normal gene function resulting from increased mRNA or protein expression.
The cell that is the precursor of all types of blood formed elements is the Hemocytoblast. The formed elements of blood, through the process of hemopoiesis, they are continually produced, replacing the relatively short-lived erythrocytes , leukocytes, and platelets. The process starts in the red bone marrow, with the hemopoietic stem cells that differentiate into myeloid and lymphoid lineages.
