The contains hydrolytic enzymes for the digestion of proteins, lipids, nucleic acids, and polysaccharides.

Lysosome

Explanation:

The lysosome is an organelle found in cells of eukaryotes.

Its functions include:

I) It contains several hydrolytic enzymes such as

- glycosidases that break down complex sugars (polysaccharides),

- proteases that break down proteins,

- and sulfatases that hydrolyze sulphur-containing compounds,

- other enzymes for lipids and Nucleic acids

II) it also digest worn out organelles, and engulfed viruses and bacteria.

III) and helps to remove wastes from the cell.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
