Lysosomes contain about 40 types of hydrolytic enzymes, All are acid hydrolases, work best at acidic pH including: proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases, and sulfatases.

Genetic exchange also happens between distantly related organisms by horizontal gene transfer, or HGT.

HGT is particularly important to prokarytotes and is the most common way by which they acquire new genes.
