This is How Your Body Makes New Cells

by Moin Uddin Ahmed Tipu

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.

So this is like "the talk" but on a celular level?

Doodelay June 1, 2020 - 4:38 AM

That plastic joke 😐

Barton Abrams June 1, 2020 - 4:53 AM

Had a thought, what is the state of the science for regeneration of lost limbs and organs? I. e. Natural replacement for limb amputation or replacement of lost or damaged organs such as kidney regeneration not replacement?

Sebastian Alba June 1, 2020 - 6:04 AM

Im somewhat of a Chromosome expert, people say I have an extra one.

Sam Allinson June 1, 2020 - 6:38 AM

I’ve got one chromosome missing which is 22q11 so the genetic condition I’ve got is 22q11 Deletion Syndrome

Micah Getty June 1, 2020 - 7:00 AM

I like the way Seeker teaches! This is a great channel and please make more episodes!

Foxy Thunder June 1, 2020 - 7:12 AM

I’m sad to see Human go, even if it’s only temporarily.

Nate Crownwell June 1, 2020 - 8:36 AM

Thank you Patrick! I loved this series!

The Finktron June 1, 2020 - 10:33 AM

Wish I would have had your excellent series when I was teaching biology in high school. You give very clear explanations that a teacher can build on to make biology much more interesting. Keep up the excellent work that you do.

I'm just glad I'm a programmer

David Ano June 1, 2020 - 12:24 PM

I hope there is a season two!

MAHESH June 1, 2020 - 1:18 PM

This channel is awesome…
Love from India

I learn more from seeker than I learn at school

Ben Hadfield June 1, 2020 - 2:07 PM

I can't stop noticing his eyes shifting as he's reading, it's driving me crazy.

Jonathan Quevedo June 1, 2020 - 5:43 PM

Do any of u guys think that they'll find a way on being immortal because they could fix ur vision or not but I have a good feeling they'll find a good cure for death. Hopefully, I'm still alive to see it.

VivaPapaya June 1, 2020 - 8:23 PM

Speaking of mitosis.. you could be my twin in this video.

Masters Kai June 1, 2020 - 8:32 PM

What you are also looking at is the evolution of camera's on smartphones

Pain Hyena June 1, 2020 - 10:07 PM

DNA is stored in the balls.

Chris Shipman June 1, 2020 - 11:39 PM

At what point do the cells become human?

Anar10n June 1, 2020 - 11:46 PM

Was a nice ride, thanks

PresidentialWinner June 2, 2020 - 3:14 AM

7:30 Nonsense. The number of people who think that (especially your viewers but generally as well) is less than the people who believe that the Earth is flat. No dumpster fires

E'Osiris June 2, 2020 - 7:50 AM

How many times are you going to redo this same video?

Pretty Prudent June 2, 2020 - 9:55 AM

Humans are All disgusting, no matter the color of hide—whether milky white or chocolate black. Primates.

Gilo Gingin June 2, 2020 - 2:10 PM

I love this Newcomer 😁

infinateU June 2, 2020 - 7:26 PM

now go over the Carcinogenic Process of digesting meat and even extracting oxygen from the air we breathe. How to COUNTER cancer through diet and cancer fighting properties and immune system boosting nutrients. Should i consume minerals before ingesting vitamins??

infinateU June 2, 2020 - 7:26 PM

where's the "Organic" Standard???

Kevin Moore June 2, 2020 - 10:23 PM

It really astounds me as to how perfectly our cells replicate most of the time, until it doesn't, and you end up with cancer.

Deeptee Shinde June 3, 2020 - 7:14 AM

Please create more better graphics

joshs dkytre June 3, 2020 - 11:13 AM

Trace sure has changed over the years.

मयंक . Mayank June 3, 2020 - 12:39 PM

Voting for another installment of this series.

All the videos were great, to say the least. Learned so much. So much resourceful information compiled in each episode. Loved the presentation and narration; interesting writing. Commend the use of graphics/photos, short clips and all the visual aid; just marvellous, superb. Always wondered why things were not taught like this in colleges using these visual aids.

Please accept my warmest gratitude, can't thank you all enough. I am extremely grateful to Dr Patrick too. I sincerely wish you were my professor.

Tshego Phale June 4, 2020 - 1:19 AM

Love it to bits. In the next season, maybe chat about cancer, and current advances in genetic engineering including technologies such as CRISPR

Brandon U June 4, 2020 - 9:01 AM

Hopefully we get another season. Seeker human was really good

Mitchell Carroll June 4, 2020 - 8:32 PM

@0:06. Aren't there ~3 billion base pairs and not 6 billion? There would be ~6 billion nucleotides

Quantum Droid June 5, 2020 - 5:00 PM

U know we already slaughtering millions of lives….why we not doing with our species too? Lets harvest those babies for stem cells…

Artem Klimov June 7, 2020 - 11:33 AM

How does amount of stem cells change in the adult organism over time? If it’s decreasing, then why, what’s the mechanism? What if we artificially support their constant high amount in the body, will it fight degenerative aging processes?

Su'udi Khoirul Anam June 9, 2020 - 6:58 AM

Many thanks for this series

elitas2cents June 10, 2020 - 3:50 AM

Now this is all good and well in the macro-view of biology but what does actually happen in the micro-view of cell-division?
When I think a tad smaller than a cell and look at the carbon, oxygen, hydrogen and sodium molecules, what kind of processes happen there?
Shouldn't there be much more interesting things happening?

How for example does such a molecule "know" which sodium ions to "catch" with magnetic fields to create another "copy" of a cell molecule?
Wouldn't that require some energy at least to form those new molecules that "catch" and bind those ions together in the same way the first cell was?
There must be a ton of chemical reactions and mini-magnetic and electron-migrations going on.
We must not forget that biology cannot exist without physics and chemistry.

BluFyre 14 June 10, 2020 - 4:17 AM

Y'all forgot to mention that they could make a biological child of same sex parents. Still under research by the way.

Kavin Bharathi June 14, 2020 - 11:09 AM

Cells multiply by dividing

Johan Van Der Merwe June 14, 2020 - 5:03 PM

Sad the series ends

Lucas Boninsegna June 14, 2020 - 7:20 PM

the telophase really looks like a human penis

Al Garnier June 19, 2020 - 5:32 PM

Induvidual life exists within the body to create the whole, just as each individual exist within the whole of humanity and humanity is an individual species within the animal kingdome.

JrPlayz 16 July 4, 2020 - 1:41 AM

clicked cause I was interested, quit cause my brain couldn't cope.

Rafael Victor July 31, 2020 - 7:43 PM

Wait, so it's over? I want learn more!!
