This video provides a broad overview of differences in gene organization, and mechanisms of transcriptional regulation in prokaryotes and eukaryotes. Lactose induction of the lac operon is used as a model of prokaryotic gene regulation (the video is intended for a non-majors introductory biology class and dual regulation by glucose is not covered). The discussion of eukaryotic transcriptional regulation is broadly focused to highlight general differences between prokaryotic and eukaryotic transcriptional control, as well as regulation through chromatin modification that is specific to eukaryotes.","styleRuns":[{"startIndex":0,"length":605,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"}]},"headerRuns":[{"startIndex":0,"length":605,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"}]}},{"itemSectionRenderer":{"contents":[{"continuationItemRenderer":{"trigger":"CONTINUATION_TRIGGER_ON_ITEM_SHOWN","continuationEndpoint":{"clickTrackingParams":"CPwBELsvGAIiEwi039X9m8iLAxWh00IFHbqdHXk=","commandMetadata":{"webCommandMetadata":{"sendPost":true,"apiUrl":"/youtubei/v1/next"}},"continuationCommand":{"token":"Eg0SC0xFNklNYWdpWUtJGAYyJSIRIgtMRTZJTWFnaVlLSTAAeAJCEGNvbW1lbnRzLXNlY3Rpb24%3D","request":"CONTINUATION_REQUEST_TYPE_WATCH_NEXT"}}}}],"trackingParams":"CPwBELsvGAIiEwi039X9m8iLAxWh00IFHbqdHXk=","sectionIdentifier":"comment-item-section","targetId":"comments-section"}}],"trackingParams":"CPsBELovIhMItN_V_ZvIiwMVodNCBR26nR15"}},"secondaryResults":{"secondaryResults":{"results":[{"compactVideoRenderer":{"videoId":"3rvOguEZP1c","thumbnail":{"thumbnails":[{"url":"https://i.ytimg.com/vi/3rvOguEZP1c/hqdefault.jpg?sqp=-oaymwE8CKgBEF5IWvKriqkDLwgBFQAAAAAYASUAAMhCPQCAokN4AfABAfgB_gmAAtAFigIMCAAQARhGIEYoZTAP
