Difference Between DNA and RNA – Burning Issues – Free PDF Download

• Life on earth is very diverse, from single-celled protozoans to complex multicellular plants and animals. But at the molecular level, all life is fundamentally made up of the same building blocks – DNA and RNA. One of the primary differences between DNA and RNA is that DNA is doublestranded while RNA is single-stranded.

DNA

• Consider the following statements.
• Deoxyribonucleic acid is the hereditary material found in almost all living organisms.
• It is made up of molecules called nucleotides.

• Which of the following statements is/are correct?

A) Only 1
B) Only 2
C) Both 1 and 2
D) Neither 1 nor 2

• DNA, or deoxyribonucleic acid, is the inherited material found in every single living creature. The deoxyribonucleic acid in an individual’s chromosomes controls a variety of visible characteristics and invisible characteristics. Visible characteristics include race, coloring and sex.
• An invisible characteristic includes blood groups and susceptibility to inherited diseases.

RNA

• RNA is a ribonucleic acid that helps in the synthesis of proteins in our body. This nucleic acid is responsible for the production of new cells in the human body.
• It is usually obtained from the DNA molecule. RNA resembles the same as that of DNA, the only difference being that it has a single strand unlike the DNA which has two strands and it consists of an only single ribose sugar molecule in it
• . Hence is the name Ribonucleic acid. RNA is also referred to as an enzyme as it helps in the process of chemical reactions in the body.
