Would it theoreticaly possible to find frozen animals 120.000 years old with still intact DNA?

I don't think this is a factual response. This appears to be some cartoon?

"so it represents an unity instead" If you are going to be pedantic, that "an" should be an "a", no?
That’s what I was thinking, yes. You have to think HOW you pronounce the word. The ‘u’ in “unity” is pronounced as “you” which starts with a consonant. Hence, you use ‘a’ not “an”.
I've always wondered this, as a non English native speaker. You could also say the "u" in unity is pronounced as "iu" which starts with a vowel and sounds the same as "you", so your reasoning sounds incorrect. Perhaps a better explanation is that the "iu" diphthong is already paired together, so attaching it to the "an" sound to form "aniu" doesn't roll off the tongue as well.

Yeah, DNA in ice has a half-life of a million years. Seems very much possible.
What does half-life mean in the context of DNA? One base pair corrupted / unrecoverable? Half of them?
half life generally means that within the time frame 50% of the material will have been destroyed or changed.
so it would mean that half of the dna might still be available after 1M years

#34Can't believe they don't show a photo of what appears to be a 10 meter in diameter, 2.7km deep hole.
The camera wouldn't take the picture, and then several of the scientists had to be sedated as they started acting strangely.
As long as they don't come up with schematics to build a white Marker...

Half of them. Which is still useful in biological samples that have billions of copies.

Yeah, you can still assemble a genome even if strands are broken. In fact this is done all the time as the size of the strands going into DNA sequencers are often only 100s or maybe 1000s of basepairs.

I think unity is just a typo for unit, not that that changes this discussion.

Given that Greenland regularly gains surface mass, even this year gaining close to 50 gigatons as of June 20th: https://nsidc.org/greenland-today/files/2023/06/SMB_Fig3_15J..., you might have to wait a few more millenia or even another 100K before the next interglacial.

But Y is a vowel?
