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 carry genetic information in cells, found in genes within the chromosomes in the nucleus.
- DNA contains instructions for organism development, survival, and reproduction, while RNA plays a role in protein synthesis.
- Both DNA and RNA are composed of nucleotides, which consist of a phosphate group, a sugar, and a nitrogenous base.
- DNA is double-stranded, while RNA is single-stranded; DNA has deoxyribose sugar, and RNA has ribose sugar.
- The nucleobases in DNA are thymine, cytosine, guanine, and adenine, while in RNA, thymine is replaced by uracil.
- Adenine pairs with thymine in DNA and with uracil in RNA; cytosine pairs with guanine in both nucleic acids.
Learn about the differences between DNA and RNA, two types of nucleic acids that carry genetic information in cells. Understand their structures, functions, and the composition of nucleotides in both DNA and RNA.
