Answer: Target cell

In cell signalling, the receptors on the surface of target cells are specific enough to differentiate between the molecules on the basis of slightest change in the chemical structure. The hormones act as ligands which bind to specific receptors on the target cell and causes change inside the cell, to start the cascade of reactions.

andriy [413]

The answer is; C

It is caused by the recessive allele because the parents appear normal but are carriers of the disorder (meaning they are heterozygous for Pseudohypertrophic muscular dystrophy). Only when the offspring is heterogenous recessive do they display the disorder.

The disorder is also sex-linked because it tends to affect only boys. This means that the disorder is probably coded for by alleles in the Y- chromosome that determines the male sex.
