Response to a signal
Overview: cellular response
- At the molecular level, we can see changes such as an increase in the transcription of certain genes or the activity of particular enzymes.
- At the macroscopic level, we may be able to see changes in the outward behavior or appearance of the cell, such as cell growth or cell death, that are caused by the molecular changes.
- Transcription makes an RNA transcript (copy) of a gene's DNA sequence.
- Translation reads information from the RNA and uses it to make a protein.
