Question

Which feature is found most often in prokaryotic cells?

Answer 1

Prokaryotic cells don't have a well defined nucleus so, they are called incipients or nucleoid. They contain only a single length of only DNA( Deoxyribonucleic acid). Their DNA is not covered by Histonee. They don't contain any cell organelles or cytoplasmic inclusions except small ribosomes which are of 70-S types.
For example, Bacteria, Blue green algae(Cynobacteria).

Thanks.

Answer 2

Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
