Question

Can’t decide between B or C 8. Eukaryotic cells undergo the process of mitosis to produce new cells of like kind. When you consider the cell cycle and the cell going from interphase to telophase initiated by the growth hormone. What phase of cell signaling is occurring when the cell goes through prophase, metaphase, anaphase, and telophase? a. The phase of cell signaling that is occurring when the cell undergoes the different phases of cell division is transduction. b. When a cell goes through prophase, metaphase, anaphase, and telophase, it is undergoing the response phase of cell signaling. It is response because each stage the cell is responding in its own different ways, for example: as the individual chromosomes migrate to opposite poles during anaphase. This is a response to the mitosis cycle in which the cell wall divide and form two sister chromatids c. The phase of cell signaling that is occurring when the cell goes through these phases is transduction. It is transduction because transduction is when a signal is converted into a form that can bring about a specific cellular response. Transduction occurs in a sequence due to the enzymes that were made during interphase. The signal in this instance is the growth hormone, and the sequence is prophase, metaphase, anaphase and telophase

Explanation / Answer

Of all three options, option (c) is the most apt response. During cell division ,the growth factor signalling pathway comes into play. The growth factor pathway has many targets, which it activates through a signaling cascade that involves phosphorylation.The result of this can be either increase or decrease in transcription of various genes involved in cell growth and division. Thus it is a signal that is converted into various forms for bringing a specific cell response. Hence it is transduction.
