Question

Prokaryotic genes contain

• A. DNA and histones
• B. DNA but no histones
• C. Neither DNA nor histones
• D. Either DNA or histones

Answer 1

The correct option is B DNA but no histones

The DNA in prokaryotes is not found in the nucleus and can be found floating around the cytoplasm region. The DNA of a eukaryote is found in the nucleus, mitochondria, and the cytoplasm. Next, eukaryotes have introns when transcribing their DNA to mRNA but prokaryotes lack that. Also, the DNA in prokaryotes is a circular shape wherein eukaryotes it is linear. Since prokaryotes lack the nucleus, they do not have histones (groups of protein found in chromatin) and eukaryotes have histones.

So, the correct answer is option B.
