The abnormal levels of four DNA bases, namely guanine (G), adenine (A), thymine (T), and cytosine (C) are implicated in several cancers, metabolic diseases, and HIV/AIDS. A) Adenine pairs with thymine in both DNA and RNA. The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). The other three basesthymine (T), cytosine (C), and uracil (U)are derivatives of pyrimidine. In RNA, adenine pairs with the base uracil; this is because there is no thymine (adenine's usual base-pairing partner) in RNA. Mnemonic in case you don't wanna logic it out: Got A Tattoo UnderCover. This specific pattern of pairing maintains a uniform width to the DNA molecule. In this work, we report on a photoionization study of the microhydration of the four DNA bases. All rights reserved. Question 3. What determines the code, or information, of a DNA molecule? In the following, selective surface-enhanced Raman modes will be analyzed. Only pairing purine with pyrimidine ensures a constant width for the DNA. 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. The main difference. Answered: 1) Use the Leontis-Westhof base pair | bartleby Guanine The chemical structure of guanine ( G) is C5H5N 5O C 5 H 5 N 5 O. 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.
