Question

DNA of chloroplast differs from nuclear DNA in

• A. Absence of histone protein
• B. Fewer bases
• C. Single
• D. All of the above

Answer 1

The correct option is D All of the above

CHLOROPLAST DNA	NUCLEAR DNA
1) The DNA is small and circular as found in a bacterial cell. 2) They lack histone proteins instead they have less complex histone-like proteins. 3) They have many copies of DNA with few nucleotides.	1) They are longer compared to the chloroplast DNA and are double-stranded. 2) They have small basic proteins called histones. 3) The nuclear DNA is linear with 46 chromosomes and contains 3 billion nucleotides.

So, the correct answer is 'All of the above'.
