During DNA replication, what would be the complementary strand to the original DNA segment of GCT AAT?

• CGA TTA

• CGA TAA

• GGA UUA

• GGU TTU

What is the role of DNA polymerase in the process of DNA replication?

• It carries genetic information to the ribosomes

• It produces a complimentary copy of a strand of DNA

• It constructs RNA chains using a template from DNA genes

• It retrieves amino acids from the cytoplasm for protein construction

Which of the following terms describes the strand of DNA that is replicated in chunks called Okazaki fragments?

• Leading strand

• Influencer Strand

• Lagging Strand

• Follower Strand

Which of the following best explains why DNA replication is considered “semi-conservative”?

• Replication always produces two DNA molecules, each having two brand new strands

• Replication always produces two DNA molecules, one having two old strands and one having two new strands

• Replication always produces two DNA molecules, each having one old strand and one new strand

• Replication always produces one brand new DNA molecule with two new strands and the original molecule is completely destroyed

Which enzyme is responsible for “unzipping” the DNA by breaking hydrogen bonds between bases?

• DNA Polymerase

• DNA Ligase

• Primase

• DNA Helicase

Which of the following is NOT a part of a nucleotide?

• 5-carbon sugar

• Sulfur Group

• Phosphate Group

• Nitrogenous Base

Which of the following is FALSE about DNA?

• It has a double helix structure

• It has two strands that are antiparallel

• It contains genetic information

• It uses the nitrogenous base uracil

DNA replication occurs in ALL somatic cells. Place the following steps of DNA replication in order.

i. DNA polymerase builds the new strand from 5’ to 3’

ii. Helicase unzips the DNA and Topoisomerase relieves tension

iii. Ligase glues DNA together

iv. Primase attaches RNA primers

• i, ii, iii, iv

• ii, iv, i, iii

• iv, iii, ii, i

• iv, ii, i, iii
