डीएनए और आरएनए की तुलना करें और इसके विपरीत करें।
DNAs and RNAs both are types of nucleic acids that play a crucial role in genetic information storage and transfer in living organisms. However, there are some fundamental differences between these two types of nucleic acids.

Comparison:

1. DNA (Deoxyribonucleic Acid) is a double-stranded helix, while RNA (Ribonucleic Acid) is usually single-stranded.

2. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose.

3. DNA has the nitrogenous bases adenine, guanine, cytosine, and thymine, while RNA contains uracil instead of thymine.

4. DNA's primary function is to store genetic information and serve as a blueprint for the synthesis of RNA and proteins, while RNA's primary function is to synthesize proteins according to the genetic information stored in DNA.

5. DNA replication occurs in the nucleus during cell division, while RNA synthesis (transcription) occurs in the nucleus and cytoplasm of the cell.

6. DNA is stable and less prone to damage, while RNA is less stable and more vulnerable to damage.

Opposite:

1. DNA is a double-stranded helix, while RNA is usually a single-stranded molecule.

2. DNA has thymine as a nitrogenous base, while RNA has uracil instead of thymine.

3. DNA is mostly located in the nucleus of a cell, while RNA can be found in both the nucleus and the cytoplasm.

4. DNA is very stable and less prone to mutation, while RNA is more prone to mutation due to its single-stranded nature and susceptibility to enzymatic degradation.
