Question

4 __ 2. Which of the sequences listed below best describes the order in which the following enzymes participate in the replication of DNA in bacteria? I. DNA polymerase I II. Helicase III. DNA polymerase III IV. Ligase

Answer 1

The correct sequence of enzymes involved in the replication of DNA in bacteria is:II. HelicaseIII. DNA polymerase IIII. DNA polymerase IIV. LigaseExplanation:1. Helicase unwinds the DNA double helix, creating two single strands of DNA.2. DNA polymerase III adds nucleotides to the growing DNA strand in a 5' to 3' direction.3. DNA polymerase I removes the RNA primers and replaces them with DNA nucleotides.4. Ligase seals the gaps between the Okazaki fragments on the lagging strand, forming a continuous DNA strand.
