Question

Maximum number of bases in plasmids is

• A. $50$ kilobase
• B. $500$ kilobase
• C. $5000$ kilobase
• D. $50,000$ kilobase

Answer 1

Answer: (B)

$500$ kilobase

Bacterial plasmids are the extrachromosomal genetic elements present in bacteria. They are separated from a chromosomal DNA and replicate individually. They contain circular double-stranded DNA as genetic material. They usually carry some genes like antibiotic resistance genes which provide added advantage to the bacteria. Maximum number of bases in plasmids is 500 kilobase.

Thus, the correct answer is '500 kilobase.'
