Here's a brief definition of each term:
1. **Transduction**: The process by which a cell converts an incoming signal (from the environment or other cells) into a biological response. This often involves a series of molecular interactions and changes within the cell.
2. **Responses**: The outcomes or changes that occur in a cell or organism as a result of a stimulus or signal. Responses can include alterations in gene expression, changes in cell behavior, or physiological adjustments.
3. **Reception**: The initial step in cell signaling where receptors on the cell surface or within the cell bind to specific signaling molecules (ligands), such as hormones or neurotransmitters, leading to the activation of signal transduction pathways.
4. **Post-Translational Modification of Preexisting Proteins**: The biochemical modifications that occur to proteins after they have been synthesized (translated). These modifications, such as phosphorylation, glycosylation, or ubiquitination, can alter protein function, activity, localization, and stability.
5. **Transcriptional Regulation**: The mechanisms that control the rate and timing of gene transcription, determining which genes are expressed in a cell at any given time. This regulation can involve transcription factors, enhancers, silencers, and other DNA elements that influence the binding of RNA polymerase and the transcription process.
