Differences between DNA AND RNA

DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid) are both nucleic acids essential for life, but they have key differences:

1. Sugar: DNA contains deoxyribose sugar, while RNA contains ribose sugar. Ribose has an extra oxygen atom compared to deoxyribose.
2. Structure: DNA is typically a double-stranded helix, with two complementary strands wound around each other. RNA is usually single-stranded, though it can fold upon itself to form complex structures.
3. Bases: Both DNA and RNA use the bases Adenine (A), Guanine (G), and Cytosine (C). However, DNA uses Thymine (T) as its fourth base, whereas RNA uses Uracil (U) instead of Thymine.
4. Function: DNA primarily serves as the long-term genetic blueprint for all known living organisms. RNA has diverse roles, including acting as a messenger (mRNA) to carry genetic information from DNA to ribosomes, as a structural component of ribosomes (rRNA), and as an adapter molecule in protein synthesis (tRNA).
5. Location: In eukaryotic cells, DNA is mainly found in the nucleus, with a small amount in mitochondria. RNA is found throughout the cell, including the nucleus, cytoplasm, and ribosomes.
