Study Notes
- DNA and RNA are types of nucleic acids, with DNA standing for deoxyribonucleic acid and RNA standing for ribonucleic acid.
- Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells and make up genetic material.
- DNA contains instructions needed for organisms to develop, survive, and reproduce, while RNA plays a crucial role in protein synthesis.
- Both DNA and RNA are made up of nucleotides, which consist of a phosphate group, a five-carbon sugar, and a nitrogenous base.
- The basic differences between DNA and RNA include DNA being double-stranded and found in the cell nucleus, while RNA is single-stranded and primarily located in the cytoplasm.
- In DNA, the sugar is deoxyribose, while in RNA, it is ribose, with the key difference being the presence of an oxygen molecule in deoxyribose.
- Adenine pairs with thymine in DNA, while in RNA, thymine is replaced by uracil, so adenine pairs with uracil in RNA.
Test your knowledge on the fundamental concepts of DNA and RNA, the essential nucleic acids in living organisms. Explore the differences between DNA and RNA in terms of structure, function, and location within the cell.
