This Megavirus has its own CRISPR-like Defense System

MIMIVIRE is the name French researchers have given to the immunity mechanism of mimivirus, and that they have now described in a new paper for Nature.

Well, for the last question, you should read our review on CRISPR. As for the rest, you might look for the answer in some of the latest research covered by well-known journal Nature.

Researchers of Aix-Marseille University (France) have published an interesting study on a type of virus called mimivirus.

They have a diameter of about 0.5 mm (enough to be seen with an optical microscope) and the size of their genomes is comparable to bacteria: physical characteristics you really wouldn’t expect from typical viruses.

Also unlike most virus types, they can code amino acids and nucleotides (proteins and DNA building blocks). So they seem to be somewhere between regular viruses and bacteria.
