1. DNA replication 1. Why is DNA replication an essential process for prganisms? a. An organism must copy its DNA to pass genetic information to its offspring. b. It allows the organism to repair any mistakes c. All organisms require two copies of DNA d. Organisms needs to reserve a copy in case if it loses one. 2. What is the function of the parental DNA in replication? a. It serves as the template for DNA replication b. It allows for the DNA to be circular c. It is passed into the offspring of the parent d. It gives the cell two complete copies of the DNA 3. Eukaryotic replication differs from prokaryotic replication, because prokaryotic replication a. typically has more replication initiation sites. b. involves only one circular chromosome. c. takes longer to copy. d. has more DNA to copy. 4. Match the enzymes with their function. a. Relax the supercoiling of DNA and helps in unwinding. b. Seals the gap between the okasaki fragments to create a continuous strand. c. Removes DNA primer and replaces it with newly synthesized DNA. d. Responsible for the synthesis of new DNA strand and proofread for accuracy. e. Responsible for unzipping the DNA helix by breaking hydrogen bonds between nitrogenous pairs. DNA polymerase III DNA gyrase Helicase Ligase DNA polymerase I 5. What are the products of semiconservative replication for a double-stranded DNA molecule? a. Two double-stranded DNA molecules, each consisting of one parental strand and one daughter strand. b. One double-stranded DNA molecule, consisting of two daughter strands. c. One double-stranded DNA molecule consisting of one parental strand and one daughter strand. d. Two double-stranded DNA molecules, one consisting of two parental strands and the other consisting of two daughter strands. 6. Eukaryotic DNA is synthesized at a faster rate than prokaryotic DNA. T/F 7. Both leading and lagging strand are synthesized only in 5' to 3' direction. T/F
