- The best definition of an endonuclease is that it hydrolyzes A. nucleotide from only the 3' -end of an oligonucleotide . B. nucleotide from either terminal of an oligonucleotide. C. phosphodiester bond located in the interior of a polynucleotide . D. bond only in a specific sequence of nucleotides. E. bond that is distal co the base chat occupies the 5' position of the bondI have a question about ''complementary nucleotides''. Books and google makes me confused. Correct me if Im wrong. Everywhere I read, it says ''nucleotides in basepairing are complementary''. But the basepairing are part of the nucleotides structure? shouldnt the basepairing in nucleotides be complementary, meaning the bases have been linked together via hydrogen bonding, which results in the shape of nucleotides???? Or do they mean that, nucleotides are complementary because their bases have formed bond with each other, which gives the shape of nucleotides?? I dont know why I dont get it. Please explain so I can understand it. Thank youPlease don't copy Chemistry All of the following tend to favor a helical conformation of a single polynucleotide chain EXCEPT: Group of answer choices A. hydrophobic interactions of the rings of the purine and pyrimidine bases that exclude water. B. charge–charge repulsion of phosphate residues of the polynucleotide backbone. C. hydrogen bonding between appropriate purine–pyrimidine pairs. D. interchange of electrons in the p orbitals of the purine and pyrimidine bases.

- This is DNA. Locate the nitrogen bases (nitrogens are blue). Where are they located in the molecule?Locate the sugars and phosphates, and describe their location. Adjacent nucleotides are linked by covalent phosphodiester bonds (-O-P-O-) produced by a condensation reaction. What parts of the adjacent nucleotides are linked by phosphodiester bonds?Two nitrogenous bases extending towards the middle of the double helix. Are there any covalent bonds between these bases?If there are no covalent bonds between these bases, what other kinds of bonds might hold the two strands of the double helix together?Using Figures 8.7 and 8.9 as a guide, draw a dinucleotide composed of C and A. Next to this, draw the complementary dinucleotide in an antiparallel fashion. Connect the dinucleotides with the appropriate hydrogen bonds. FIGURE 8.9 The two polynucleotide chains in DNA run in opposite directions. The left strand runs 5 to 3, and the right strand runs 3 to 5. The base sequences in each strand are complementary. An A in one strand pairs with a T in the other strand, and a C in one strand is paired with a G in the opposite strand. FIGURE 8.7 Nucleotides can be joined together to form chains caled polynucleotides. Polynucleotides are polar molecules with a 5 end (at the phosphate group) and a 3 end (at the sugar group).
