1. Virus can naturally reproduce outside a host cell.

2. Virus is a living organism.

3. A single Virus contains both RNA and DNA.

“M13 Bacteriophage” sometimes seen in the news is

A. Drugs that deal with anti-microbial resistance

B. Virus

C. Bacteria

D. Protozoa

Answer: B

Recently, scientists have developed a Virus M13 Bacteriophage that is used to speed up the computers.
How this VIRUS Works?
There is a time delay between transfer and storage of information between a traditional RAM chip and a hard drive. This M13 Bacteriophage reduces that milliseconds time delay as low temperature construction memory can be achieved by this.
