Thanks for stopping by, this is 2 minute classroom and today I am giving you three fun facts about mitochondrial DNA.
#1 - All of your mitochondrial DNA comes from your mother (at least in most cases). And she got hers from her mother, and so on and so forth through all the mothers of history.
This is because you come from a sperm and an egg, the sperm from your father and the egg from your mother. The egg is a complete cell with all of the organelles, including mitochondria. The sperm, on the other hand, is just a DNA delivery pod bringing the father's DNA to the mother's egg.
As a result, you most likely got all of your mitochondria and its DNA from your mother.
Fun Fact #2 - Mitochondrial DNA is round, not linear like the DNA in your nucleus. And it is completely separate from the DNA in your nucleus, they never interact.
The 27 genes on your mitochondrial DNA code for specific proteins used by the mitochondria, such as ATP synthase.
And
Fun fact #3 - Your mitochondria has its own DNA because it was once a bacteria that was engulfed by early ancestors' eukaryotic cells.
This is called the endosymbiotic theory and it essentially states that an early single-cell organism engulfed a mitochondria-like bacteria and enjoyed its energy-producing properties so much that it decided to partner with it forevermore.
It’s a great love story.
If you are currently studying DNA and genetics (or anything, really) then check out my test prep playlist to dominate your next test.

For those curious about that mitochondria exception, the sperm also carries mitochondria, the bulk of it in its tail. Sometimes, the mitochondria can get into the egg from the sperm cell. However, most times, it is degraded. Most, times. If it's incorporated, then the offspring could also have an mtDNA line from a different matrilineal line through the male's mtDNA donation. Cool huh? :-)

[@72drowssap]

Any chance that I can convince you to share your source for that information? An Official source? It is my understanding that Mdna in sperm is always destroyed in the egg. Thanks in advance if you are able to come through!

[@KayAccords]

Do you get superpowers if you get Mtdna from your dad?

[@RiDankulous]

Thanks for commenting about this. Your expert opinion is valuable to the community.

[@robertbostrom9529]

I drew the endosymbiotic theory for some homework and I just remembered how great this story was ha ha

[@2MC]

It really is, haha.

[@HeyGavn]

I like how simple and informative your videos are.

[@FaithEducation]

very useful video!! I shall introduce this channel to my students to motivate them to study Biology well. Thank you for those videos!! Support!

It's a classic love story where two find each other as the result of so much serendipity it seems their union must have been born from fate. A love so powerful it fuels the hearts of all that Love. 😘💕💕💕💕💕💕💕💕

Hello,can you make a video about nervous system🌹

[@katylewis7118]

Can you explain MT ND1 please

[@عبداللهحنفي-ر3ص]

37 Gene's of DNA not 27

[@thomasolson7447]

I imagine there is more to it. I'm sure it was quite common for an organism to pack man an aerobic eukariote. Some organisms had to benefit more than other and there had to have been a transfer of dna. Creating a symbiotic relationship.

[@superjjewii]

Thank you :)

[@hadii_alhaj]

Helo, is there 27 genes on mtdna or 37??

[@fasilkohli1555]

37

[@KanakaBae]

Coulda been a typo

Hi may i ask, if mitochondrial DNA part of our genome

where did this man go thats the real qestion?

Hey!! I have a question. What happens to the plates and the mantle at plate boundaries?

impressive

[@pradhashanmahalingam4315]

Why did you stop posting u make good cotet

[@VinnyTheRed]

Just because you get your mitochondrial DNA from your mother doesn’t mean you are solely your mother’s ethnicity. Ethnicity is very complex and mitochondrial DNA is a small percentage of your DNA.

[@madhumitaroy1159]

But sperms too contain mitochondria in it to provide energy to the sperm cell

[@jaaa4865]

Very nice, we want it translated into Arabic if you please

[@TheNameanonymusamogus]

Is the last one really a theory now? The last time I have read of it it was just speculation

[@Mdebacle]

All humans have mtDNA from one of three haplogroups, conveniently coded L,M,N, with the region of intersection being southwest Asia. This is because all humans have mtDNA from one of the three daughters-in-law of Noah.

[@2MC]

Except that we've now observed male inherited mtDNA in some cases.

[@Mdebacle]

@@2MC That would explain why Neanderthal and Denisovan mtDNA is so divergent from anything. They were 15-16ths human and 1-16th chimpanzee.

[@DrReginaldFinleySr]

lol.

[@Mecal21]

Mitochondria are the power house of the cell. I know I know, I know too much.

I still don't know what it is.
