Question

Nucleotides/nucleic acids occur in

• A. Ribosomes
• B. Mitochondria
• C. DNA, RNA, chloroplasts and nucleus
• D. All the above

Answer 1

The correct option is D All the above

Nucleic acids are DNA and RNA. DNA is a genetic material which is mainly present in the nucleus of the cell in eukaryotes. In prokaryotes, they lie freely in the cytoplasm. The functional segment of the DNA is known as genes. Mitochondria and chloroplast are the only organelles which are semi-autonomous which have their own DNA. Mitochondrial DNA is known as mt-DNA and the chloroplast is known as ct-DNA. Ribosomes have m-RNA in abundance for translation into proteins.

So, the correct answer is option D.
