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.

The gastrointestinal wall is composed of four layers or tunics:
- Mucosa
- Submucosa
- Muscularis mucosa
- Serosa
The innermost tunic of the wall is known as the mucosa or mucous membrane layer. The digestive tract's lumen is lined with it. The mucosa comprises epithelium, a layer of lamina propria, a loose layer of connective tissue, and the muscularis mucosa, a thin layer of smooth muscle.
The mucosa is surrounded by a substantial layer of loose connective tissue known as the submucosa. Blood arteries, lymphatic vessels, and neurons are also present in this stratum. The adventitia is a connective tissue that makes up the digestive tract's outermost layer above the diaphragm. It is referred to as serosa below the diaphragm.
