To explain: The ability of various cell types to respond differently to the same signaling molecule by differential gene regulation.
Introduction: Cells respond to the changing environment such as light, water, nutrient that causes some change in cell and help in adapting in a new environment. A multicellular organism has various types of cells which communicate with each other with the help of signaling molecules.
To explain: The importance of differential gene regulation to multicellular organisms.

- What are two specific and different ways that neurotransmitter signaling at the membrane alters gene expression in the nucleus?arrow_forwardHow machinery of gene regulation is controlled by cell signaling? (Cell signaling books ) (Signal transduction books)arrow_forwardRAS is a signal transducer that acts as a switch for turning on cell division. Drag the descriptions below to their proper places on the figure to show the sequence of events. When growth factor binds to the receptor, the intracellular domain activates RAS by facilitating exchange of GDP for GTP. When no growth factor is bound to the extracellular receptor, RAS is bound to GDP and is inactive. RAS activates the first of three sequential kinase proteins termed the MAP kinase cascade. Cell proliferation proceeds as the machinery for cell division is set in motion. The end result of the MAP kinase cascade is activation of a transcription factor.

- What are the two major mechanisms through which cell signaling leads to a change in cell behavior?arrow_forwardIf some cell-surface receptors, including Notch, can rapidly signal to the nucleus by activating latent transcription regulators at the plasma membrane, why do most cell- surface receptors use long, indirect signaling cascades to influence gene transcription in the nucleus?arrow_forwardWhat is a second messenger? What are two second messengers that are involved in signaling pathways downstream of GPCRs and explain how they are produced? long answer: If you wanted to compare a cardiac muscle cell with a skeletal muscle, how could you use RNA sequencing to identify genes that are differentially expressed? In your answer, explain this technique and describe what type of information you can learn from it. If RNA sequencing led to the identification of two genes, gene X and gene Y, what are two experiments you could do to study the functions of these two genes?arrow_forward
- You stimulated the cell with a ligand and analyzed the response. Upon ligand treatment, the cell increased the expression of gene α and decreased expression of gene β. When you inhibit cyclic AMP production by treating the cell with an inhibitor of Adenylyl cyclase, the increased expression of gene α was not observed but the decrease gene β expression was still observed. a) What you can expect for gene α regulation by this ligand? What signaling mechanism could be used? b) To determine how gene β is regulated by the ligand via what signaling mechanism, provide your hypothesis and indicate a potential experiment that you can perform to test that.arrow_forwardEukaryotic signal transduction pathways often involve multiple proteins transmitting a signal from the cell surface to the nucleus. What advantage is gained through the use of multiple steps? Many signal transduction pathways are used in different cell types for entirely different purposes, leading to the transcription of different genes. How might different cell types be able to use a single signal transduction pathway to bring about such different results?arrow_forwardWhy is the signaling pathway that activates NF-κB considered to be relatively irreversible compared with cytokine or RTK signaling pathways?arrow_forward
- The G protein coupled receptor (GPCR) pathway elicits diverse intracellular responses in different cells. The basic steps of GPCR signaling are outlined in this diagram. Which of the following statements correctly describes the process of GPCR signaling? The GPCR activation is reversible after the signal of the ligand diminishes. The membrane-embedded enzyme uses GTP as a secondary messenger to initiate gene expression. The ligand attaches to both the GPCR and the membrane-embedded enzyme to activate the GPCR pathway. The ligand-bound GPCR sends a GTP molecule to an enzyme in the membrane and switches it into an active state.arrow_forwardHow Are Signaling Pathways Organized and Integrated?arrow_forwardThe figure below shows how normal signaling works with a Ras protein acting downstream of a receptor tyrosine kinase.
