Assertion :- It is the metabolic, physiological or environmental conditions that regulate the expression of genes. Reason : The genes in a cell are expressed to perform a particular function or a set of functions.

Assertion: Insulin forms hormone receptor complex which regulate gene expression. Reason: Insulin is a peptide hormone which can easily pass cell membrane to interact with hormone-receptor complex.

Assertion (A). Hormones interacting with cell surface receptors do not enter the target but they generate second messenger Reason (R ). Glucocorticoids bind to intracellular receptors and regulate gene expression
