"Genes Are Blueprints Executed Literally"
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A gene functions as a regulated template rather than a literal blueprint, since its expression depends on regulatory context a cell applies.
Show
The same globin gene is expressed in developing red blood cells and left largely silent in skin cells, despite identical DNA.
Watch for
A blueprint executes the same way regardless of context — a gene's expression depends on signals this unit traced.
