Which cell specimen is a prokaryote?
A Cell 1
B Cell 2
C Cell 3

Cell 3

Explanation:

One of the unique main characteristics that differentiates a prokaryote from a eukaryote is the absence of presence of nucleus in their cell, and where their DNA is found.

In prokaryotic cells, nucleus is absence. The DNA of prokaryote is not found in a nucleus, rather, it is contained in a region referred to as nucleoid.

Therefore, the specimen that does not have DNA in nucleus is definitely a prokaryote.

Cell 3 is a prokaryote.

well the answer is 2!
