Module 17Describe the function of sigma factorsThe function of sigma factor is to initiate the transcription of a given geneDraw DNA and its RNA transcript and illustrate important sequences for recognition of RNAP and ribosomesDescribe how genes may be regulated at various points within gene expression, including non transcriptionallyGenes may be regulated by various points within gene expression by converting genes into functional proteins and enzymes by regulating transcription or translation.Illustrate the molecular processes of – Repression– Induction– ActivationDetermine the state of each regulator of the lac operon given environmental conditionsThe expression of lac operon in given environmental conditions can be expressed when lactose is present as the only carbon source.Indicate functions and steps of two component systemsThe function of a two component system is the sequence of events in a typical signal transduction pathway. The steps are binding to receptor antophogholuation, phosphate is transferred to response regulator protein, and P-RR binds DNA. The names of the component involved are sensor kinase protein and response regulator proteinDescribe basic mechanism of quorum sensing and why a cell would use QSThe basic mechanism of quorum sensing is autoinducer that increases the concentration as a function of the cell density.The cell would use QS to sense how many of their own kind are in the immediate environment. Explain non-transcriptional mechanisms of gene
