Untangler of Knots: The Amazing Topoisomerase Molecular Machine
Ғылым және технология
Topoisomerase II is an extremely important enzyme in your cells that is designed to untangle knots and supercoils in DNA strands that arise during replication and transcription. It does this by grabbing two tangled DNA segments, holding one steady while it breaks the other segment in two, and then passing the first segment through the break. The second segment is then reconnected, and the two DNA segments are released, having been successfully untangled. Without topoisomerases, chromosomes would become an impossible mess, making DNA replication, transcription, and cell duplication impossible.
The carefully orchestrated untangling activity of topoisomerase II doesn’t happen by accident. This enzyme is a molecular machine that only works because its amino acid sequence is highly specified to provide a special shape and structure necessary for its function. In other words, topoisomerase enzymes contain high levels of complex and specified information-a hallmark of intelligent design.

I'm really loving all your research, may God bless you all for doing this and bringing the truth for all to see
Wow, the only thing I wish they would have explicitly pointed out is that the structure of that enzyme is coded for by the very DNA that it untangles. But without that untangling, the DNA quickly wouldn't be able to be read to build the molecule that untangles it. One of the 800 gazillion chicken or the egg problems in Biology that naturalistic explanations fall prey to but design explanations explain.

What’s amazing is that you have networks of machines that work in unison, for example the kinetics of the topoisomerase is driven partially by ATP… which itself requires multiple complexes (F1FO ATPase) to synthesise in sufficient quantity.. which of-course are themselves gene products, so what we have is a beautiful labyrinth of closed loop systems that are interdependent.

Really I’m curious. How does god offer a better explanation of our existence when now you have to explain god’s existence as well. If us being very complex being demands a creator to explain our existence. How much more so would the existence of a fabulously complex being like god demand a creator. It seems to me the simplest answer seems more likely

So, these untangling things, made of proteins, would have had to have been around before there was a double-helix, or made at the same time. There is no possibility that they were made after. And, since the DNA contains the instructions for building proteins...my head officially hurts now. It's almost as if someone knew what they wanted the finished product to do first, then designed the mechanisms to get it done.

The amazing thing is, if just one step in this process is missing, the whole process breaks down. Evolutionists would say this process would require millions upon millions of years to evolve but then DNA would never survive beyond the first "knot"...Topoisomerase had to foresee the knots, in order to form the mechanisms needed to untangle them. Nature is wonderful but not all knowing...this had to be designed by an ALL KNOWING DESIGNER! Science is wonderful but even more wonderful when we know the DESIGNER personally and His love for us, when when we are twisted up in knots. John 1:14 The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth. 15 (John testified concerning him. He cried out, saying, “This is the one I spoke about when I said, ‘He who comes after me has surpassed me because he was before me.’”) 16 Out of his fullness we have all received grace in place of grace already given. 17 For the law was given through Moses; grace and truth came through Jesus Christ. 18 No one has ever seen God, but the one and only Son, who is himself God and[b] is in closest relationship with the Father, has made him known.

It probably started as a simpler protein, such as a messenger protein, and evolved into something more efficient.
It's mind boggling to think that inanimate molecules could create such a complex molecular mechanism by itself for such a specific purpose with the same sophistication and capability of modern "Designed , Engineered and Programmed"" quality control equipment which is used to both analyze and then remove any defective parts and replace with new materials. Who would have realized how absolutely brilliant inanimate molecules can actually be.
And science struggles to explain the formation of simple amino acids , but yet have no problem explaining away the specified information required to build a multitude of purpose specific nano machines at the same exact time .In this case it has to have the ability to proof read thousands to billions of DNA , correct any mistakes and physically remove entanglements.If there's any area of science that lacks any critical insight , it has to be the origins of life with the main tenents of evolution a close second.
God Bless
I was just untangling my sons' kite strings the other day. Spent a lot of time wondering if there's an algorithm for it and guessed there isn't. Very difficult. Should have had some of those molecules to help.

But no man...a completely random chance mutation was selected...by something we don't care to explain, because of a reason we don't care to elaborate on, by a process that we don't want to reveal the origin of (being that the mechanism of selection infers a modicum of intelligence at the least). That's how all of these super complex machines and processes developed... Even though they, by default, required themselves to pre-exist themselves in order to be formed to begin with... Look, I'm trying my hardest to play devil's advocate here but to even remotely believe in the nonsense I just typed infers a level of infantile hubris that I can't fathom. When you can explain to me what the first selection mechanism was that created the first selection mechanism then I'll listen... Until then we have to assume it was intelligence.

Playing devil's advocate i'd say that you can rate intelligence from zero to some upper limit , then microorganisms have intelligence close to zero but not zero, as epigenetics show that environnent influences genetic expression of the offspring . Let's say a bacteria has a "will" to metabolize A in an ambient full of B , then it starts "willing " to metabolize B too , so its offspring begins to try and metabolyze B with varied results until one "learns" the trick and shares it like bacteria do .

Great video explanation; however i do take issue with the final comment of intelligent design. Regarding ID’s specific claims, scientists object that the concept of "irreducible complexity" relies upon a mischaracterization of biological mutation as a relatively linear process involving only the addition of more and more "parts," rather than a dynamic process that can also reshape, rearrange, or fundamentally alter existing elements and features. Systems that must be fully formed to serve their current function could have developed from earlier forms that served a different function, or could be significantly reorganized versions of an earlier form that served the same function. The human eye is a fine example of and lack of ID....The squid and the octopus, for example, have a lens-and-retina eye quite similar to our own, but their eyes are wired right-side out, with no light-scattering nerve cells or blood vessels in front of the photoreceptors, and no blind spot!
What an amazing GOD we serve! It is such a blessing to see things like this. It really helps to put things into perspective for me. The total power of "In the beginning GOD" is evident in evrything around us, and more or His amazing power is being shown and proven every day! Thank you to those that put this together for the rest of us!
Incredible that all this may have all started as RNA. I mean, the switch to DNA likely occurred because NRA is exposed to the rest of the machinery within the cell while a nucleus has a relatively pristine environment giving DNA based life a natural advantage over RNA based. Hence why you'll only find RNA based cells to be extremely simple in nature. The drawback being that, as this video shows, keeping all the items in the "RNA vending machine" that is DNA exposes it to dangers that RNA likely didn't have to deal with. No doubt, the topoismerase started off as another protein, perhaps as one of the messenger proteins that travel across microtubules that somehow managed to untangle "protoDNA" strands and became more specialized as natural mutations found a more efficient means of entangling DNA. I'm wondering what it might have started out as, but unfortunately, that's hard to figure out at the atomic level since there are no fossils at this level as all the atoms are scavenged and nothing is left from previous mutations to compare it to. It still makes me wonder what it evolved from.
You forgot to give credit to the Creator; it's not difficult, you can do it...
"What is responsible for life on earth?" Discovery Science: 4:18
as long as you have enough "faith" in the not so enough time for evolution , everything is possible. may the farce be with us all.

As the apostle Paul wrote, "God's invisible qualities are clearly seen from the world’s creation onward because they are perceived by the things made, even his eternal power and Godship." (Romans 1:20) The more one peers into creation the more clearly one sees that Jehovah is an excellent designer, architect, builder - creator. Thank you for presenting this video! Excellent!

Because the starting point for discovery in all of cellular biology comes from assuming the observation of the machinery in naturally occurring, forming a number of disprovable hypothesis for the observation, then rigorously testing them until you're left with one that has failed to be disproven and going with that until a better test/hypothesis replaces it.
But how do they discover this?
