Question

What is the name of the region where double-stranded single circular DNA is found in the Prokaryotic cell? (a) Proto nucleus (b) Nucleus (c) Nucleoid (d) Nucleoplasm

Answer 1

Answer:

In the prokaryotic cell, the DNA-containing area is the nucleoid and the correct option is (c)

Explanation:

• In the prokaryotic cell, well-organized nuclei, Golgi body, and mitochondria are absent. The nucleus of the prokaryotic cell is irregular in shape and lacks a membrane. This type of nucleus in the prokaryotic cell is known as the nucleoid. It is the DNA-containing area.
• The nucleus is the controlling center of a eukaryotic cell. The components of the nucleus are the nuclear envelope, nucleolus, nuclear matrix, nucleoplasm, and chromatin. Chromatin is a mixture of DNA and protein (mainly positively charged histone proteins) and is present in the nucleus of the eukaryotic cells.

Hence, the correct option is (c)
