Signal transduction pathways that include a phosphorylation cascade are generally initiated by a phosphorylase enzyme and limited to one step
are generally inactivated by a kinase enzyme and decrease signal transduction efficiency
are propagated by steroid hormone receptors to reach the final cellular response in one step
cause a structural change in each phosphorylated protein, with the addition of a phosphate group to activate the protein

Signal transmission paths Learn how signals are transmitted within a cell from the cell membrane receptor. The chains of molecules that pass intracellular signals are known as intracellular signal transduction pathways.

a. autosomal.

explanation:

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
