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.
