Professor James Eberwine explains that gene expression within a cell is dynamic - changing in various ways as a cell ages.
Transcript:
Gene expression within a cell is dynamic. At the birth of the cell you have certain levels of gene expression, as a cell ages you get different levels of gene expression. Various types of pharmacological behavioral disease-related in cells can change gene expression. It is those changes that underline again the physiology associated with the function that you’re looking at.
Professor James Eberwine discusses what we might see were we to take a snapshot of the internal dynamics of a living cell, which might resemble Grand Central Station during rush hour.
Professor James Eberwine describes three ways in which experiences can change the gene-expression: changing RNA translation, movement, and potentially production.
Professor James Eberwine describes the primary functions of RNA-binding proteins, which include regulating tRNAs, degrading RNAs, synthesizing RNAs, and regulating multigenic gene expression.
Professor James Eberwine discusses the structural changes in a cell related to long-term potentiation. These include changes in the shape of dendritic spines.
