.For 32 students. You need frozen strawberries. Here's a low tech way to master some high-tech topics and help the abstract become concrete. By extracting DNA from strawberries (not included), you gain an understanding of the tremendous length of the DNA molecule and you will be better able to visualize it. Simply crush frozen strawberries and use the included solutions to release cell components and precipitate DNA. Kit includes: 3 bottles...
