Q. Autonomously replicating circular extrachromosomal DNA of a prokaryotic cell is called:

NTA AbhyasNTA Abhyas 2020Biotechnology : Principles and Processes

Solution:

Plasmids are defined as small circular molecules of DNA which are capable of replicating independently and do not rely on chromosomal DNA of the organism. Due to this feature, they are also referred to as extra-chromosomal DNA. They are found in bacteria, archaea and various eukaryotes. The recombinant DNA is generated by combining DNA from two or more sources. Satellite DNA is DNA sequences with small segments, repeated many times.
