Question

If you fractionate all the organelles from the cytoplasm of a plant cell. In which one of the following sets of fractions will you find nucleic acids?

• A. Nucleus, mitochondria, chloroplast
• B. Golgi bodies, mitochondria, chloroplast, glyoxysome
• C. Lysosome, chloroplast, cytoplasm and peroxisome
• D. Lysosome, mitochondria, chloroplast, Golgi bodies

Answer 1

The correct option is A Nucleus, mitochondria, chloroplast

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are collectively called as nucleic acids. They are made up of monomers called as nucleotides. Most of the genetic material (DNA) of plant cell is present in nucleus. Mitochondria and plastids also possess their own genetic material (DNA). Chloroplast is one of the type of plastid. Ribosomes are ribonucleoprotein complex, i.e., they possess RNA. Ribosomes are present freely in cytoplasm. Hence, cytoplasm will also show traces of RNA.

So, the correct answer is 'Nucleus, mitochondria, chloroplast'
