Arrange the steps of DNA replication in the order that they occur.
First step
Helicase unwinds the DNA double helix.
Last step
Answer Bank
DNA polymerase synthesizes DNA. RNA primers are added. DNA ligase joins DNA fragments together.
RNA primers are removed. Single-stranded DNA-binding proteins bind to each template strand.
Which of the following statements BEST describes the process of DNA Replication?
Group of answer choices
The two strands of the parental molecule separate and serves as template for synthesis of a new strand.
Each new strand is identical to its template strand.
Each strand of both daughter molecules contains a mixture of old and newly synthesized DNA.
The two parental strands reassociate after acting as templates for new strands restoring the parental double helix.
Some Processes Involved in DNA Replication
The replication origin is identified.
DNA primase builds RNA primer.
Okazaki fragments are spliced by DNA ligase.
Helicases bind and uncoil the DNA double helix.
RNA primer is the starting point for DNA polymerase.
DNA replication ends at the telomere where DNA codes for termination.
DNA polymerase adds complementary nucleotides in the 5' to 3' direction in short segments called Okazaki fragments.
The sequence in which the events numbered above occur during DNA replication of the lagging strand is:
