Answer:
d.They prevent the two parental strands from coming together again.
Explanation:
During the process of DNA replication, the two DNA strands should be separated from each other to serve as a template. To separate the two DNA strands, the helicase enzyme breaks down the hydrogen bonds between the complementary base pairs of the DNA strands. The process uses ATP as a source of energy.
Due to the presence of complementary base pairs, the separated DNA strands have a tendency to reanneal by the formation of hydrogen bonds. To prevent the reannealing of separated DNA strands, single stranded binding proteins bind to them. Binding to single stranded binding proteins to the separated DNA strands does not allow them to reanneal.

Answer:
It stimulates the host cell to produce antiviral toxins, which are released continually into respiratory tract, to destroy the viral cells before they are recognized by the white blood cells.
The right option is; D) mitosis
In multicellular organisms, life begins as a single cell until mitosis occurs, causing growth.
Mitosis is a process of cell division, and a part of the cell cycle in which a single cell divides, and produces two identical daughter cells (new nuclei) that contains the same shares of the parent’s cell part. Mitosis occurs in multi cellular organisms, and its primary purpose is for growth, and to replace worn out cells. Mitosis contains four basic stages which are; prophase, metaphase, anaphase, and telophase.
