Biofilms: the ultimate survival mechanism

By Debosree Pal, JNCASR, India

Communication and decision making often form the keys to survival at the cellular level. Intracellular and intercellular communications have been well established through signaling pathways in multicellular organisms. The often undervalued unicellular denizens of the living world utilize such strategies in rather intelligent fashion to accomplish survival mechanisms in extreme conditions.

Why bacteria are smarter than we think they are

Because of this, bacteria have developed some effective systems to protect themselves. These systems, known as restriction-modification (RM) systems, come in a variety of shapes and sizes but it has always been thought their primary function is a defensive one against invading viruses and other invading DNA.
