Gene regulation in eukaryotes

Gene regulation in eukaryotes – This lecture explains about the eukaryotic gene regulation. Regulation of gene expression entails a vast variety of mechanisms which can be utilized by cells to expand or shrink the creation of particular gene products (protein or RNA), and is informally termed gene legislation. Subtle packages of gene expression are greatly found in biology, for illustration to set off developmental pathways, reply to environmental stimuli, or adapt to new food sources. Virtually any […]

Gene regulation in prokaryotes

This lecture explains about the Gene regulation in prokaryotes. Regulation of gene expression entails a broad range of mechanisms that are used by cells to develop or diminish the production of specific gene products (protein or RNA), and is informally termed gene legislation. Subtle applications of gene expression are greatly located in biology, for example to trigger developmental pathways, respond to environmental stimuli, or adapt to new food sources. Practically any step of gene expression may also […]

Gene Regulation

031 – Gene Regulation Paul Andersen explains how genes are regulated in both prokaryotes and eukaryotes. He begins with a description of the lac and trp operon and how they are used by bacteria in both positive and negative response. He also explains the importance of transcription factors in eukaryotic gene expression. Do you speak another language?
