1.2E Nucleic acids
Term | Definition |
---|---|
adenosine triphosphate | ATP high-energy molecules used by the cell to synthesize macromolecules, such as carbohydrates and proteins |
complementary base pairing | the formation of weak hydrogen bonds between nitrogen-containing bases; T always pairs with A, C with G |
cytosine | nitrogenous base in RNA and DNA. bonds with guanine |
deoxyribonucleic acid DNA | twister ladder codes for the order in which amino acids join to form a protein; sugars and phosphates form a linear sugar-phosphate-sugar backbone, and the bases project from the sides of the backbone. adenine A + T thymine guanine G + C cytosine |
double helix | twisted ladder structure of DNA |
guanine | nitrogenous base in RNA and DNA. bonds with cytosine |
ribonucleic acid RNA | conveys DNA's instructions for the amino acid sequence in a protein |
nitrogenous base | an alkaline containing nitrogen A adenine, G guanine, C cytosine, T thymine |
nucleic acids | DNA and RNA, both polymers of nucleotides |
nucleotide | ATP 3 parts: phosphate group, pentose sugar (ribose), nitrogen-containing base |
phosphate | |
thymine (T) | nitrogenous base in DNA. bonds with adenine |
uracil (U) | nitrogenous base in RNA. bonds with adenine |
