The last class of organic molecules are the nucleic acids. There are two varieties: ribonucleic acid, or RNA, and deoxyribonucleic acid, or DNA. These polymers are long chains of components called bases, of which there are only five types. RNA is a single-strand molecule; DNA is a spiral of two cross-connected strands. DNA carries information. Part of the DNA in a cell is genes, which code for protein molecules. Each type of receptor, or enzyme, or neurotransmitter, has a stretch of DNA in which its sequence of amino acids is coded.
- DNA has a nitrogenous base called Thymine, but RNA doesn't. Instead, RNA has Uracil. In DNA thymine pairs with adenine, but in RNA uracil pairs with adenine. ... Differences: - DNA is double-stranded, RNA is single-stranded. - DNA contains a pentose sugar Deoxyribose, RNA contains the pentose sugar Ribose. A pentose is a 5-carbon sugar molecule. - DNA is limited to the nucleus, RNA is made in the nucleus, but can travel outside of it. - DNA has a nitrogenous base called Thymine, but RNA doesn't. Instead, RNA has Uracil. In DNA thymine pairs with adenine, but in RNA uracil pairs with adenine. - There is only one type of DNA but 3 kinds of RNA (messenger, transfer and ribosomal RNA) Similarities: - DNA and RNA are made up of monomers called nucleotides.
