a. Pharmaceutical drug that function To decrease serotonin in the synapse are one type of treatment for clinical depression.-FALSE

Serotonin is known as happy hormone.Increase in serotonin creates happy mood.In depressed indviduals serotonin is low, thus drugs that function to decreasse serotonin is not a treatment for clinical depression.

b. tumor suppressor genes encode proteins that normally act to drive the cell cycle forward.FALSE

Tumor is the uncontrolled growth of cells.In order to suppress tumor the cell cycle has to be inhibited, thus tumor suppressor genes encode proteins that inhibit cell cycle.

c. a single allele of an oncogene can result in uncontrolled cell division TRUE

A single allele of an oncogene can result in uncontrolled cell division as the mutation of one allele of a proto oncogene can convert it to oncogene as it can overexpress the gene product needed to drive the cell cycle forward.

d. neuro transmitters are types of proteins expressed in neurons.FALSE

neuro transmitters are not proteins, they are endogenous chemicals like amino acids, monoamines , peptides.
