|
1. It is self replicating, DNA molecule found naturally in many bacteria and yeast. 2. It is not essential for normal growth and division and contains information for a few traits. |
1. Chromosomal DNA present in chromosomes of all organisms. 2. It is essential for growth and division and contains information for all traits. |
