I'm familiar with SV40 promoters, but I have no real hands on experience. So Wacka would be an expert in this particular field whereas another molecular biologist like myself is not. I'm conversant at best. At least this is the way it used to be prior to March 2020....
This is now 2023, everyone's an expert on anything they want to be just by saying so. Just like you can switch your sex by wishing it. Its all in your mind man!
So when charlatans like @ChiGoose bloviate all day about the law and how nobody understands it like him, I say ***** you dude! Your rules, everyone's an expert in everything now....
