Regulation Of Gene Expression

Asseration : The bacteria and other prokaryotes show high adaptability to the changing environent. Reason : Member of kingdom Monera are efficient in regulating gene expression.

Assertion :- The development & differentiation of embryo into adult organism are the result of coordinated regulation of expression of several sets or genes. Reason : The expression of all genes are not required simultaneously during development of organism.

The hormone which regulates the gene-expression of the target cell is

Hormone that regulates gene expression by interaction with genome through the hormone receptor complex is

Hormone which regulate gene expression or chromosome by interation of hormone receptor complex with the genome are

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

Read the following statements and select the correct option. Statement A : Only steroid hormones are able to cross the cell membrane and act via intracellular receptors. Statement B : Steroid hormones stimulate regulatory genes present on the chromosomes and thus regulate gene expression
