1. When DNA replication starts (A) The hydrogen bonds between the nucleotides of two strands break. (B) The phosphodiester bonds between the adjacent nucleotides break. (C) The bonds between the nitrogen base and deoxyribose sugar break. (D) The leadi If the guanine content of a c...
The phosphodiester bonds that link adjacent nucleotides join the 3'-hydroxyl of one nu What type of bond between the complementary bases of DNA stabilizes the double helix structure? A. covalent B. ionic C. hydrogen D. nuclear In the double helix structure of DNA, which of the nitrogenous ...
intercalation results in rotation of the base adjacent on one side compared to the C2 symmetry-mate base on the other side. The next base over is also affected and therefore the phosphates positioned 2 nucleotides away from the compound (nucleotides +1 to +4) are affected. This moves the sc...
Biaryl scaffolds are found in natural products and drug molecules and exhibit a wide range of biological activities. In past decade, the transition metal-catalyzed C–H arylation reaction came out as an effective tool for the construction of biaryl motif
The genetic code is locked within the arrangement of DNA bases called nucleotides, which base pair with each other to create the DNA double helix. Answer and Explanation: The structure of a nucleotide is a nitrogenous base bonde...
A correct statement about "peptide bonds" is that they are A) covalent bonds between a nitrogen and a carbon B) hydrogen bonds formed between two amino acids. C) formed between nucleotides in a DNA molecule. D) linkages between sugar groups in a polysa ...
How are the adjacent nucleotides in a single strand of DNA joined together? A. Hydrogen bonds between adenine and thymine and cytosine and guanine. B. Hydrogen bonds between deoxyribose and phosphate. C. Covalent bonds b...
