DNA (Deoxyribonucleic Acid) and RNA* (Ribonucleic Acid) are both nucleic acids essential for life, but they have key structural and functional differences. Structure: DNA is typically a double-stranded helix*. RNA is usually single-stranded*. The sugar in DNA is deoxyribose, while the sugar in RNA is ribose*. DNA uses the nitrogenous base thymine (T), whereas RNA uses uracil* (U) instead of thymine. Both contain adenine (A), guanine (G), and cytosine (C). Function: DNA serves as the long-term genetic blueprint* for an organism, storing hereditary information. It is found primarily in the nucleus of eukaryotic cells. RNA plays various roles in protein synthesis* and gene regulation. There are several types of RNA, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), each with a specific function in translating genetic information into proteins. RNA is found in both the nucleus and the cytoplasm. Stability: DNA is more stable due to its double-stranded structure and deoxyribose sugar, making it suitable for long-term storage of genetic information. RNA is less stable due to its single-stranded nature and ribose sugar, which is more reactive. This makes it suitable for its transient roles in gene expression. Drop the next question
