Understand how multiple layers of gene regulation shape cell function and development. Explore DNA and chromatin modifications, transcriptional regulation, and the influence of transcription …

Key points: 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 …

Gene expression and regulation Trace the flow of genetic information from DNA to RNA to protein. Examine how transcription, mRNA processing, and translation work together to carry …

However, there are also some meaningful differences in how transcription factors are used in humans. Humans and other eukaryotes are complex: we're made up of trillions of cells …

Summary: DNA is divided up into functional units called genes, which may specify polypeptides (proteins and protein subunits) or functional RNAs (such as tRNAs and rRNAs). Information …

But even the simplest bacterium has a complex task when it comes to gene regulation! The bacteria in your gut or between your teeth have genomes that contain thousands of different …

Unit 14: Gene regulation About this unit This unit is part of the Biology archive. Browse videos and articles by topic. For our most up-to-date, mastery-enabled courses, check out High School …

Prokaryotes rely on gene regulation for environmental adaptation, while eukaryotes have more complex interactions and a nuclear envelope for added control. Understanding gene …

Activity: How can gene mutations help us understand the formation of flowers? In this hands-on activity, students will investigate how genetic mutations affect flower development by analyzing …
