Question
Which statement about genetic regulatory networks IS NOT TRUE? A. regulatory networks are often associated with the differentiation of stem cells whereas the activation of a cell-type specific transcription factor results in its own activation (a positive feedback loop activation mechanism) and therefore creates a memory mechanism that persists over several generations B. in development, often a linear sequence of transcription factors encoding genes, where the first transcription factor activates a second and the second a third constitutes a linear activation network C. a genetic regulatory network (a sequence of transcription factor encoding genes which activate each other) is insufficient to regulate the hundreds of cellular events that happen during cell differentiation and or development D. a linear sequence of transcription factors that activate sequentially and finally activate themselves create some sort of memory of activation
Explanation / Answer
Ans- the statement stated in the option (C) is not true.
Because genetic regulatory network along with transcription factors are sufficient to regulate the hundred of the cellular and developmental processes because regulatory network is consist of DNA, RNA and protein required for cellular and developmental processes.
