WebOct 25, 2024 · Phosphoric acid has 2 ester bonds in DNA. You have somehow confused an ester and an ether bond. R X 1 − O − R X 2 is an ether bond, R − O − X is an ester … WebSep 2, 2024 · DNA uses hydrogen bonds instead of covalent bonds due to their weak properties. However, covalent bonds are stronger than hydrogen bonds. In this way, during transcription and translation, DNA double helix has two strands are separated into daughter strands by the easy breakdown of hydrogen bonds.
WebA special type of covalent bond called a phosphodiester bond forms between nucleotides. These phosphodiester bonds form the two strands that make up the DNA molecule. But this question is asking us what bonds form between base pairs to hold the two strands together. So we can rule out (E) because phosphodiester is not the correct answer. 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 …
WebAbstract. DNA containing 5-azacytosine (azaC) has previously been shown to be a potent inhibitor of DNA-cytosine methyltransferases. In this report, we describe experiments which demonstrate that azaC-DNA forms a covalent complex with Hpa II methylase, a bacterial enzyme that methylates the internal C of C-C-G-G sequences. 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.
