Question

Put the following steps of DNA replication in chronological order. 1. Single-stranded binding proteins attach to DNA strands. 2. An RNA primer is created. 3. Primase binds to the origin. 4. DNA polymerase begins to synthesize DNA 5. Hydrogen bonds between base pairs of antiparallel strands are broken. A. 5, 1, 3, 2,4 B. B. 3, 1, 5, 4,2 C. 1,5, 3, 4,2 D. 3, 5, 1, 2,4

Answer 1

A. 5, 1, 3, 2, 4

Step-by-step explanation:

In the DNA REPLICATION PROCESS, first the DNA is unwound by the help of helicase enzyme. Following this, the bonds between base pairs are broken down to seperate the two strands. Now, to prevent rebinding, Single stranded binding proteins come and stabilize the DNA. This is followed by activity of primase which syntheisizethe RNA primer. Finally, DNA polymerase catalyzes the reaction by adding more nucleotides. And then, ligase joins the strands and completes the process.
