Question

What is one defining feature of a prokaryotic cell?

a) "Presence of membrane-bound organelles"
b) "Nucleus with DNA"
c) "Large size"
d) "Lack of membrane-bound nucleus"

Answer 1

The defining feature of a prokaryotic cell is the lack of a membrane-bound nucleus; genetic material is located in the nucleoid region.

Step-by-step explanation:

One defining feature of a prokaryotic cell is the lack of a membrane-bound nucleus. Instead of a nucleus, the genetic material in a prokaryotic cell is found within a central part of the cell called the nucleoid. Prokaryotic cells also generally lack other membrane-bound organelles, which are typical of eukaryotic cells, such as mitochondria, the endoplasmic reticulum, and the Golgi apparatus. Instead, they have a simple structure with a single chromosome made of circular DNA located in the nucleoid region.
