HELP IM CONFUSED?
a model of a signal transduction pathway that results in the transcription of mRNA
What is the best description of what would happen if the phosphorylation cascade did not result in a phosphate being attached to the transcription factor?
1. mRNA would not stop being translated from the DNA.
2. Phosphorylation cascade would continue to release excess phosphates.
3. Transcription factors would bind to the DNA.
4. Receptor proteins would not bind to the signaling hormone.
