Answer:
The correct answer will be option-DNA polymerase can only add nucleotides to the free 3' end
Explanation:
DNA replication process produces the exact copy of DNA which requires various enzymes. The function of adding a nucleotide to the daughter strand is performed by the enzyme called DNA polymerase.
The DNA polymerase enzyme catalyses the process of DNA replication which requires energy provided by the dNTP. The enzyme adds new nucleotides at 3'-OH end of the DNA which favour the reaction energetically.
Thus, the new DNA strand appears to be elongated in the 5' to 3' direction.
Answer;
-Telophase
Explanation;
-The spindle apparatus disintegrates during the telophase of mitosis. Telophase is the final stage of mitosis.
-During this phase, the sister chromatids reach opposite poles. The small nuclear vesicles in the cell begin to re-form around the group of chromosomes at each end.
-As the nuclear envelope re-forms by associating with the chromosomes, two nuclei are created in the one cell. Telophase is also marked by the dissolution of the kinetochore microtubules and the continued elongation of the polar microtubules.
