Question 1 1 pts Why is it important for DNA to have complementary base pairing? O Complementary base pairing allows base pairs to be packed in the most energetically favorable arrangement inside of the double helix structure. O Complementary base pairing will pair a purine with a purine, which are a similar width, thus they are able to hold the sugar-phosphate backbone an equal distance apart along the DNA molecule o Complementary base pairing is only important for maintaining the...

Which is the best reason for adenine base-pairing with thymine in DNA? A.) The two molecules covalently bond together. B.) Both are large bases and, therefore, bond tightly. C.) Both are small bases and, therefore, bond tightly. D.) These two bases fit together like jigsaw puzzle pieces.

Which of the following statement about DNA is FALSE? When bacteriophage DNA was shown to be the agent necessary for production of new phages, this was the early experiment demonstrating that DNA is the hereditary material. During DNA replication, two replication forks are formed to complete the synthesis of the entire chromosome in eukaryotes. During bacterial DNA replication process, replication forks move in opposite directions away from the origin of replication The molecular structure of DNA...

Question 2a Deoxyribonucleic acid (DNA) is made up of nucleotides. Which part of the nucleotide stabilizes the structure of DNA using weak van der Waals interactions (stacking) and using hydrogen bonds? (Note that covalent bonds are not included in that sentence.) a. the deoxyribose sugar b. the ribose sugar c. the phosphate d. the nitrogenous base e. the amino acid Question 2b This ability of the nitrogenous bases to exist in more than one form can lead to incorporation of...
