Explanation:
Detailed explanation-1: -Prokaryotes generally have cell walls and some organelles such as ribosomes. However, their unique feature is that they do not have. Since they do not have membrane-bound organelles, they also do not have nuclei. Prokaryotes still contain DNA that consists of nucleic acids, but they float freely in their cytoplasm.
Detailed explanation-2: -In prokaryotes, the DNA is arranged in the irregular-shaped region known as the nucleoid. Hence we can say that the prokaryotes can survive without a nucleus.
