Blue green algae or cyanobacteria acquire the specialized cells known as heterocysts. Heterocysts is the site of $\mathrm{N}_{2}$ fixation. It contains an enzyme nitrogenase, which help in nitrogen fixation. This diagram shows the hetrocysts of Nostoc bacteria.

Restriction endonucleases are isolated from some bacteria. Their role in bacteria is:
1 defence against virus
2 synthesis of proteins
3 act as genetic material
4 help in reproduction
Explanation:
Restriction endonucleases are naturally present in the bacteria where they provide protection against invading viral DNA. Hind II was first restriction endonuclease to be isolated and characterized. Today more than 900 restriction enzymes have been isolated from over 230 strain of bacteria.
