Linkage mapping

Gene Mapping- Maps based on recombination rates are called genetic maps. 

Physical mapping- Maps based on physical distances are called physical maps.

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.
