Put the following steps in order to show how the hormone prolactin can regulate gene expression.
• regulatory protein binds to DNA and attracts RNA polymerase
• regulator protein is activated and enters nucleus
• casein gene is transcribed
• prolactin binds to its receptor
• mRNA moves to cytoplasm and is
1) prolactin binds to its receptor
2) regulator protein is activated and enters nucleus
3) regulatory protein binds to DNA and attracts RNA polymerase
4) casein gene is transcribed
5) mRNA moves to cytoplasm and is translated to produce casein protein
