Plus, get practice tests, quizzes, and personalized coaching to help you YES, but only in DNA-to-RNA (e.g., transcription) and RNA-to-RNA (e.g., translation) pairings. It allows something called complementary base pairing. Reddit and its partners use cookies and similar technologies to provide you with a better experience. M.W. As seen above, complementary bases bond together through hydrogen bonds, formed when electronegative atoms (atoms strongly attracted to electrons, which gives them a slight negative charge) come close to slightly positive hydrogen atoms (hydrogen atoms only have one proton, so they are only weakly attached to their electrons. Two of the bases, cytosine (C) and thymine (T), are single-ringed structures known as pyrimidines. flashcard sets. Na+, Mg2+, and Zn2+ binding to all tautomers of adenine, cytosine, and Since the carbons in the sugar are numbered one to five, the sugar end of the strand is called the 3' end and the phosphate end of the strand is called the 5' end. The origin of the term base reflects these compounds' chemical properties in acidbase reactions, but those properties are not especially important for understanding most of the biological functions of nucleobases. Transcribed Image Text: . Author: Bruce Alberts, Alexander D. Johnson, Julian Lewis, David Morgan, Martin Raff, Keith Roberts, Peter Walter. This difference in strength is because of the difference in the number of hydrogen bonds. The 3' end of one strand can hydrogen-bond with the 5' end of the other strand. Each of the base pairs in a typical double-helix DNA comprises a purine and a pyrimidine: either an A paired with a T or a C paired with a G. These purine-pyrimidine pairs, which are called base complements, connect the two strands of the helix and are often compared to the rungs of a ladder. Antibody Structural Components & Function | Chains & Domains: Overview & Examples. They both have two carbonyl (C=O) groups, but Cytosine, the last pyrimidine, has only one plus an amine group.
