Andrew Murray is professor of molecular and cellular biology and Director of the Bauer Center for Genomics Research (CGR) at Harvard University.
Demonstrating the method that cells use to ensure that cellular functions progress in the correct order, Murray states,
"My goal is to explain what some of those tasks are, what the consequence of failing to finish the first task before the second is, and
the way that cells try and avoid that."
Introducing the relationship between cells, chromosomes, and people, Murray demonstrates how cells reproduce by a
specialized form of cell division where women's eggs and men's sperm each contribute 23 chromosomes, jointly creating a cell containing
46 chromosomes. Dividing by a process called meiosis, cells form an embryo and eventually people, and thereby replicate and transmit their
genetic information.
