I remember one of my TA labs using strawberry
mashed in the extraction buffer made of 100ml shampoo+15g salt in 1L water,
then add 1.5 teaspoon meat tenderizer. After filtered through cheesecloth,
go through ethanol precipitation (v:v 1:1) . Stir with a glass stick and you
will see the white sticky strawberry DNA. Since strawberry has multiple
haploid so very easy to get DNA.
Hope this may help.

啊呀,这么一说我也记得好像大学的时候做过类似的实验,也是有那么一步
是用玻璃棒来搅,能看到一些东西缠在上面。
