The human genome is pretty big, but tree genomes are even bigger!

A huge thank you as always to my Patreon patrons. I did not charge them for this video (because charity) but their support is still absolutely invaluable.

PS: I'm going to additionally donate any ad money that this video makes before Dec 29 to the #TeamTrees page. More trees! - Věda a technologie
Love the comparison at the the beginning. My brain can’t easily picture more than hundred of pieces of thing, so anything in the billions is totally lost on me. Nice work Alex!
Same! I was truly shocked at how much rice it would be, I really thought it would be around a shopping-cart full. I still hope to be able to make this comparison some day, I just need a good connection to a rice company? The rice genome is around 400,000,000 bases, so that might almost be doable!
Your hair is amazing
Fantastic Alex! So cool.
Thanks!
When it comes to big numbers, multiplication rocks! For example, a minute of watching this marvelous FullHD video is enough to see how 3 billion individual pixels are flashing before your eyes
LOL, when I clicked on the notification, I read the video title as "How big are tree gnomes", and I found it funny :)
Happy to see that I wasn't the only one to misread it like that.
@@Soonjai Now all we need to do is find ourselves some tree gnomes to measure ;)
Never knew I wanted to know the answer to this question until now XD
So here I am, snacking on Wasabi peas wondering why wasabi makes my nose burn and I come across a reddit thread that lead me to a video from almost 8 years ago.
Come to your profile, read "Life Lab DNA," and my face lit up.Do you do research? Your smile glowup!! Can't wait to get home and get through your other content!
yay a new video!
They come in waves! This month will contain at least two, likely three, but maybe four? I really need to work on my scheduling...
Super cool video Alex! Thanks for making these videos =)
I'm glad you liked it! Thank you for watching!!
Un-scientific remark: I totally dig the little digitial swining tree at the end. Scientific remark: I really liked your presentation: It leaves enough time and things open to pose questions at what was presented. "Diploid": So, there are genoms with more the two base pairs (or in this cases copies of gens from parents)? "Hexaploid": So six? What could be the benefit... etc.
3.2 billion is easy to conceptionalize. Just imagine that Bill Gates and Jeff Besos have much more money than that
Those Canadian and Californian Redwoods and Sequoia trees are absolute marvels. I love all trees regardless of species or origin, and so on, but those are just... the vastness of them is f*ckin' incredible! It's almost alien how humungous they are 😳😄😊
mind boggling how many cells are in a giant redwood tree - probably a few orders of magnitude more than the number of DNA base pairs in it's genome.
Oh interesting. I now really want to make a chart of how different organisms cell numbers vs genome sizes differ...
Evolution of organisms with very long lifetimes is something I've never fully understood. It kind of flies in the face of the normal way I think about evolution in terms of changing allele frequencies in successive generations where the distant ancestors no longer affect the current population. In terms of population mechanics, the reproduction cycle length of these long-lived trees should still be roughly annual which implies the number of offspring a single organism can generate is enormous. Additionally, the multiploidal genomes suggest that there could non-trivial variability in a single parent over its lifetime which could lead to different mutations being passed on to different offspring. It's not unreasonable, then, that offspring of different ages would have different levels of difference from their shared parent. Of course, the overall answer is that the two thousand year-old trees are still very much like the hundred year-old ones, so the differences aren't _that_ big. It would still be interesting to know if any has (or could?) quantify that drift. I would expect the differences to be greater than short-lived (say, tens of years) organisms with roughly similar reproduction cycle lengths.

It would help to have that in the description!
Question: Would an animal that is homozygous have a smaller genome than several billion pairs? I have a feeling that horizontal gene transfer and recombination of alleles might play a roll in reducing this but it's been a few years.
Billions in general are just a ridiculously huge concept. A billion seconds ago, my parents hadn't met.
I wonder if tardigrades or some other equally charismatic micro-organisms would be small enough to show in billions
1 billion average size (0.1 mm long, 0.025 mm wide) tardigrades would fit in a space of 3 cubic inches if tightly packed.
@@stevethecatcouch6532 Oh so it would be on the right scale then :D
tree genomes. Or, treenomes, if you prefer.
What exactly is a gene? How does it start and end inside the genomes?
@@Biologin Thanks, this was a great answer, It got me looking at some wiki pages, now that I had something specific to google.
"joke start"
I will now start working on modifying the human genom such that it only contains transcript parts, way carry around all that junk. The cop is not half full or half empty, it is unnecessarily large.
"joke end"
I think you mean "treenomes"
I am pretty sad that I missed the opportunity to use another "ome."
Do you get to know how many trees were donated through your link? I just finally donated to #TeamTrees for the first time through your link btw; great video!
Thank you so so much for donating! I can't see a way to measure donations specifically through my button in the CZcams Studio, but there must be a way! I will keep searching because I'd love to know!
Wait, doesn't every one have 205 000 lbs of rice lying around? Just me? Well ok then, no wonder I can't find a place for the couch to go.
At 2:22 using 160! looks like factorial, so it's a bit confusing.
Nevertheless this video is still awesome!
Ohh, good point. I was just excited by the large number but I should have been more careful about my notation!

Woo Hoo! I'm Bald!
Thank you for helping to keep my analogy working! I was like "Oh I have just too many subscribers... but wait!!"
