Question

Quantity of nucleic acids in animal cells is

• A. 2-5%
• B. 5-8%
• C. 10-13%
• D. 15-18%

Answer 1

Answer: (B)

5-8%

Cells have two types of nucleic acids deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). In a eukaryotic cell, DNA is present in nucleus and cell organelles like mitochondria and chloroplast. RNA in a eukaryotic cell is present in the cytoplasm, nucleoplasm, and organelles like mitochondria and chloroplasts. Much more RNA is present in a cell than DNA. An abundant form of RNA is rRNA, which is a component of ribosomes. Add together roughly 1 percent of the total cell weight is the quantity of DNA and 6 percent of the total cell weight is the quantity of RNA.

So, the correct answer is option B.
