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. Expression of genetic information involves cellular and molecular mechanisms. 7.1 the student can connect phenomena and models across spatial and temporal scales. 3.18 the student is able to describe the connection between the regulation of gene expression and observed differences between different kinds of organisms. Gene regulation i. prokaryotic gene regulation constitutive genes = always needed constantly transcribed other genes are only transcribed when needed a. lac operon model in prokaryotes genes are regulated at transcription 3 genes for lactose metabolism in e ondna:.

Gene regulation i. prokaryotic gene regulation constitutive genes = always needed constantly transcribed other genes are only transcribed when needed a. lac operon model in prokaryotes genes are regulated at transcription 3 genes for lactose metabolism in e ondna:. In vertebrate cells, this methylation process helps in gene regulation by binding to clusters of 5 methylcytosine, which ensures that the bound gene remains in the "off" position. methylation acts as a control mechanism for gene expression, as it can prevent the transcription machinery from accessing the gene and initiating gene expression. 16.2 prokaryotic gene regulation. the regulation of gene expression in prokaryotic cells occurs at the transcriptional level. there are two majors kinds of proteins that control prokaryotic transcription: repressors and activators. repressors bind to an operator region to block the action of rna polymerase.
