(2) The chemical signal combined with a cytoplasmic receptor
(3) An increase in the nuclear concentration of the chemical
(4) An increase in mRNA synthesis
(5) Genes are activated
A) 2, 1, 3, 5, 4
B) 2, 4, 5, 3, 2
C) 2, 3, 5, 4, 1
D) 2, 3, 4, 5, 1
E) 1, 2, 3, 4, 5

Question

Quizplus · Accepted Answer

The chemical signal first combines with a cytoplasmic receptor (2), then increases in nuclear concentration (3), leading to gene activation (5), which results in increased mRNA synthesis (4), and finally increased protein synthesis (1).
