WebMar 1, 2024 · Identify the sugar, phosphate, nitrogenous base, 5' and 3' carbons in a nucleotide and the key difference between DNA and RNA. Explain the structure of the double helix, including the role of hydrogen bonds and covalent (phosphodiester) bonds. Explain why the abundance of A is roughly equal to T and G is roughly equal to C in DNA. WebThis forms a covalent bond between the oxygen sticking off the 3’ carbon of the first nucleotide, and the phosphorous atom in the phosphate group that sticks off the 5’ carbon of the second nucleotide. ...

WebIn DNA and RNA, the phosphodiester bond is the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another, deoxyribose in DNA and ribose in RNA. Strong covalent bonds form between the phosphate group and two 5-carbon ring carbohydrates (pentoses) over two ester bonds.
Web15 hours ago · No. of H- bond = 2 * No. of AT base pairs + 3 * No. of GC base pairs. Hence, if 100 base pairs are present in a DNA structure with 30 AT base pairs and 70 GC base pairs the number of hydrogen bonds can be calculated as follows: No. of H-bond = ( 2 X 30 ) + (3 X 70 ) = 270 H-bonds. The DNA molecules that consist of more GC-rich regions … edp tradingWebCovalent bonds; hydrogen bonds between nitrogen and oxygen atoms in the backbone hold secondary structure together. C.
