Control of gene expression in prokaryotes pogil answers

A gene is expressed in a cell to perform one or many functions. It helps a cell respond to various internal and external changes. Genes control the synthesis of proteins and proteins control the structure, metabolic functions and development of an organism. The two steps involved in the synthesis of a protein are transcription and translation.

Genetic Control of Development Regulating gene expression is especially important in shaping the way a multicellular organism develops. Gene regulation is the process of controlling which genes in a cell's DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA. The set of genes expressed in a cell determines the set of proteins and ...

A few exceptions include red blood cells, which contain no DNA in their mature state, and some immune system cells …The most direct way to control the expression of a gene is to regulate its rate of transcription; that is, the rate at which RNA polymerase transcribes the gene into molecules of messenger RNA (mRNA). Figure 9.1.1 The lac DNA transciprtion. Gene transcription begins at a particular nucleotide shown in the figure as " +1 ".An operon is a cluster of coordinately regulated genes. It includes structural genes (generally encoding enzymes), regulatory genes (encoding, e.g. activators or repressors) and regulatory sites (such as promoters and operators). The type of control is defined by the response of the operon when no regulatory protein is present.Read This ! The regulatory mechanisms in the operons in Model 1 and Model 2 of this activity are both considered negative control of the genes because they both involve a repressor protein that turns the operon `` off . `` L t \ Oper ns are said_ co ~ave ~ositive control when a pro~ein or enzyme can turn them `` on '' or enhance their v function by making It easier for RNA polymerase to bmd to ... Figure 16.2 Locations of gene regulation. The regulation of gene expression occurs at multiple steps going from DNA to the functional gene product, usually a protein. It begins with chromatin structure making the DNA more or less accessible for transcription by RNA polymerase. In eukaryotes, the primary mRNA transcript must be processed before ... Prokaryotic Gene Regulation. In bacteria and archaea, structural proteins with related functions are usually encoded together within the genome in a block called an operon and are transcribed together under the control of a single promoter, resulting in the formation of a polycistronic transcript (Figure 1).Short tail = short lifespan = briefly needed proteins.
