Question

The size of genome of {Methanococcus jannaschii is _________

• A. 1830 kb
• B. 1660 kb
• C. 569 kb
• D. 12,500 kb

Hint:

Archaean genomes are generally smaller than eukaryotic genomes.

Answer 1

The Correct Option is B

Step 1: Understanding genome size.
Genome size refers to the total amount of DNA present in an organism.

Step 2: About {Methanococcus jannaschii. It is an archaean whose complete genome was one of the first to be sequenced.

Step 3: Genome measurement.
The genome size of {Methanococcus jannaschii} is approximately 1.66 megabases, i.e., 1660 kb.

Step 4: Conclusion.
Therefore, the correct genome size is 1660 kb.
