If we want to become a functioning human being, we need to have cells grow and replicate. In the final episode of this Human season, Patrick will explain the cell cycle and why we aren’t just clones of our parents.

Nearly every cell in our bodies has roughly six billion base pairs. As our cells continue to grow and replicate our DNA copies its genetic data into the new cells, and while the occasional copying error happens, it only happens about one in ten thousand base pairs.
That’s pretty impressive, right?
On top of that our bodies have checkpoints in place to make sure the errors that do occur get tossed out so they don’t harm us.
DNA is massive and complex, and in today’s Human, Patrick discusses how the cell grows and replicates. We’ll explore the purpose of cell division, the role chromosomes play, and so much more. Watch to find out, and be sure to check out our last episode on how exactly DNA works:

Mitosis versus meiosis
“Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.”
“Packaging is the reason why the approximately two meters of human DNA can fit into a cell that is only a few micrometers wide. But how, exactly, is DNA compacted to fit within eukaryotic and prokaryotic cells? And what mechanisms do cells use to access this highly compacted genetic material?”
Replication and Distribution of DNA during Mitosis
“Most cells grow, perform the activities needed to survive, and divide to create new cells. These basic processes, known collectively as the cell cycle, are repeated throughout the life of a cell.”
This Seeker health miniseries will dive deep into the cellular structures, human systems, and overall anatomy that work together to keep our bodies going. Using the visual structure and quick pacing of Seeker’s Sick series, these human bio-focused episodes will give a new audience an inside look on what’s happening inside all of us.
