WebEach nucleotide comprises deoxyribose sugar and a nitrogenous base with a phosphate bond. Nitrogenous bases found in DNA: Adenine (A), thymine (T), guanine (G), and cytosine (C). Adenine and guanine are called purine bases. Thymine and cytosine are called pyrimidine bases. A pairs with T and G pairs with C by 2 and 3 hydrogen bonds, respectively. Weba double-stranded DNA molecule and slide along the helix until they recognize a specific sequence of base pairs which signals the enzyme to stop sliding. The enzymes then digest (chemically separate) the DNA molecule at that site—called a "restriction site"—acting like molecular scissors, they cut DNA at a specific sequence of base pairs. WebDec 18, 2024 · The ‘deoxy’ prefix denotes that, whilst RNA has two hydroxyl (-OH) groups attached to its carbon backbone, DNA has only one, and has a lone hydrogen atom attached instead.
