JCVI-Syn3A has been around for a while. Here is the genome sequence from 2018 - https://www.ncbi.nlm.nih.gov/nuccore/1241355755 Back at FreeGenes we synthesized all of the genes from this organism with codon optimizati

DNA is way more stable than RNA. Since you can easily synthesize RNA from DNA, and DNA synthesis technology is much more mature, folks normally synthesize DNA and then derive/make the RNA from it. That makes most researches default to

Answers: a) From the mRNA you can learn the amino acid sequence of the protein very quickly. You absolutely cannot (yet) learn the function of the protein from that sequence - normally, people just do comparisons with proteins whose functio

They are more complex, but the cell type doesn't matter as much. In fact, there are bacteria that cause disease using HGT ( https://en.wikipedia.org/wiki/Agrobacterium ). Modification of those bacteria is how you ge

Josiah is an interesting guy because it turns out his opinions hold quite a bit of nuance and he’s generally a good guy (not a snake oil salesman). I think he definitely had that perspective going in - the point of the experiment is partly

Josiah Zayner did one that looked fairly promising (believe it was either an mRNA or DNA vaccine), but unfortunately he got banned from a lot of media (like youtube) for it, so that may partially explain why you haven't seen or heard m

The gaps are usually homopolymers and such, which should get helped by R10 pores. But true, at low coverage, things can get tougher!

At the 2014 DEFCON Biohacking village I did exactly that. I gave out like 50 tubes of plasmid, all you had to do is go sequence em to extract the private key, and boom, you get like $200 (or like 15K today...) Literally nobody did it for a

The errors are non-random. That's why they use machine learning to figure out those errors. You could, of course, also just do traditional statistics on sequences that you want to sequence all the time. I've done that with plasmid

Yea automated sample preps are key for me. The main thing that is overlooked in synthetic biology about nanopore is it has the capability to dramatically lower cost of indexing, which turns out to be one of the main prohibiting costs for dr

No. Oxygen screws a lot of things up. Also, RNAses are now everywhere (organisms secrete them all the time, which is why RNAse away is a product), and since the original replicating molecules were likely RNA, pretty much the entire world is
