Just have a few Biology questions. Hope you can help, don't have to answer them all. Thank you so much.
1. A series of steps by which a signal outside a cell causes a functional change inside the cell
2. Determine the ability of a cell to respond to an extracellular signal.
3. The processes where certain genes are prevented from being expressed by chemical modifications and other means.
4. A signaling response in which there is a metabolic change due to a hormone.
5. A nucleotide sequence that is recognized by RNA polymerase, which initiates transcription.
Thanks again.
