Gene editing from home?

Question

I was watching something on youtube (Scientific Discoveries The Public Is unaware Of (r/Askreddit)) and one of the comments was something along the lines of "it is very easy to edit genes from the comfort of your home. The materials are readily accessible, along with the literature on how it is done."

Assuming this isn't just a troll comment, how does someone even go about altering genes?

Update:

I gather then it was a troll comment.

Update 2:

The video can be found here https://www.youtube.com/watch?v=KQTWQHeN-hQ

Update 3:

Sorry, 13:19

Answer 1

"it is very easy to edit genes from the comfort of your home. The materials are readily accessible, along with the literature on how it is done."

Sure, as long as a room in your home has been converted into a well-equipped molecular biology laboratory, and you know what you're doing.  If you're good at hunting up used equipment, you might be able to pull that off for less than $100 k

So, you pick a gene, isolate it's DNA and you've edited it.  So you've got a modified DNA sequence in a little tube.  Now what?

Answer 2

that's bullcrap.

You have billions of sets of DNA. The only time it's feasible to do any editing is when you are still a zygote, still one cell, right after a sperm meets an ovum.

There's nothing easy about it
