Hormone that enters the nucleus and changes the pattern of gene expression?
|
Nonsteroid hormone
|
|
Secondary messenger
|
|
Steroid hormone
|
|
Hypothalamus
|
Explanation:
Detailed explanation-1: -Steroid hormones regulate gene expression posttranscriptionally by altering the stabilities of messenger RNAs. Biol Reprod.
Detailed explanation-2: -Steroids pass into a cell’s nucleus, bind to specific receptors and genes and trigger the cell to make proteins. Amino acid derivatives, such as epinephrine, are water-soluble molecules derived from amino acids (the building blocks of protein).
Detailed explanation-3: -After binding to the ligand (steroid hormone), steroid receptors often form dimers. In the nucleus, the complex acts as a transcription factor, augmenting or suppressing transcription particular genes by its action on DNA.
