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...
QUESTION 3 The form of replication used by DNA is conservative. semiconservative. O dispersion. cumulo-nimbus QUESTION 4 The short fragments of the lagging strand are called Okazaki fragments. polymerase leading segments radioactivity molecules. QUESTION 5 0.5 points Which of the following are symbols for the four bases that are part of the make up of a DNA molecule? O A BT, G O CGAH O ATG,C O A U,G,C QUESTION 6 0.5 point In DNA replication, helicase is a protein...
Please answer all Question 1 (0.5 points) Why is there a lagging strand and a leading strand during replication? O Because the helicase unwinds the dna in only one direction. Because DNA polymerase can only add nucleotides to the 3'end of a chain of nucleotides and replication proceeds in both directions. b) c) Because a primer must be laid down first. because DNA polymerase lacks proofreading ability. Save Question 2 (0.5 points) What step(s) in polymerase chain reaction are necessary...
Question 1 DNA and RNA belong to which of of these categories of macromolecule? Pick all that APPLY Options: A.Carbohydrate B.Lipid C.Protein D.Nucleic acid E.Water Question 2 A certain molecule of DNA contains exactly 22% adenine. How much cytosine would you expect to find in this molecule? options A. 11% B. 22% C. 28% D. 56% E. 88% Question 3 The two sides of a double helix run in opposite directions (they are antiparallel). What does this mean? Options A....
Question 33 2 pts Which of the following statements about the process of DNA replication is true? It involves the enzyme DNA ligase, which corrects point mutations. It utilizes DNA polymerase, which catalyzes the reaction that adds a new nucleotide to the growing strand. The sequence on the new strand is always identical to one of the old parent strands. Adenine pairs with guanine, and cytosine pairs with thymine. Question 34 2 pts The DNA base...
Question 14 1 points Save Answer DNA replication poses several challenges to the cell that must be resolved for replication to proceed. All of the following are cellular solutions to the challenges posed by DNA replication except... O A. Helicase unwinds to the DNA to allow the replication fork to form. O B. Primase synthesizes an RNA primer since DNA polymerase can only extend an existing polynucleotide chain. O C. Higher eukaryotes utilize multiple origins of replication to reduce the...
