Small circular DNA molecules that are found in bacterial cells are called 

a Plasmid.

Ok so; Most bacterial chromosomes contain a circular DNA molecule. There is no free endings to the DNA. If there was a free ending to the DNA it would otherwise create a significant challenges to the cells with respect the DNA replication and stability. For the cells that don't contain chromosomes with DNA ending or telomeres (most eukaryotes), have a acquired elaborate mechanisms to overcome these challenges. but however the small circular DNA molecule is called a plasmid. hope this helps you!!

The virus is considered to be are living item since they have hereditary material dnas or rnas. they can imitate and change. they respond to boosts, for example, radiation, chemicals, and warmth. they have antigenic properties. they are proficient to duplicate with a same hereditary constituent.
