Drew Berry's 2003 scientific animation from the Walter and Eliza Hall Institute shows how DNA is wrapped and copied inside the cell. The proteins that do the copying are drawn as molecular machines.

HN passes it around as the best visual account of DNA replication, which turns an abstract process into something you can watch.

“here's a pretty cool video that explains what happens at the protein level”

Some amazing animations that show some of the primary operations related to DNA: Transcription (copying sections of DNA into RNA) - link Translation (turning messenger RNA into proteins) - link RNA Splicing (removing non-coding sections of mRNA) - link DNA Wrapping & Replication(two part video) - ▶ this video One thing I would encourage folks to do as you listen to the narration of these is to consider any time words are used that imply agency and remember that these are basically blobs of magnets in a jostling goo. You'll find the names Drew Berry and WEHI referenced in most of these. There are many more stunning and IMHO profoundly informative examples of biological machinery from them on youtube.

For anyone interested in the molecular process of DNA replication, here's a pretty cool video that explains what happens at the protein level. It's always amazing to watch what is in practice a molecular-sized machine: ▶ this video

I think this is more around the mechanisms of abiogenesis rather than how a single celled organism became Brock Lesnar. The process detailed here (▶ this video) no doubt has been refined through evolutionary pressures, but even the earliest of organisms must have had something similar take place in order for the traits encoded into DNA to be passed from generation to generation. This mechanism is something we can barely observe with the most advanced technology available to us, let alone reproduce or synthesize on our own. I think this is what the original question was about, where did that first process come from?
