The name comes from a latin word meaning to glue or bind together. DNA ligase catalyses the joining of DNA fragments (usually those produced by restriction enzymes). Thus different genes can be put into vectors and moved into other hosts.
A lysosome is a membrane-bound sac found in cells that contains digestive enzymes which break down complex molecules or structure.
Lysosomes are single membrane organelles or vesicles that contain enzymes and are specialized to breakdown complex food materials such as sugars and proteins, into simpler substances.
Lysosomes are made in a process that begins in the endoplasmic reticulum and ends in the Golgi apparatus which puts the finishing touches to the lysosome before releasing it into the cytoplasm where it floats freely until engaged.
