Complementary strand of a DNA sequence.
Replication fork formation.
Transcription initiation.
Okazaki fragment synthesis.
The Correct Answer is C
Transcription initiation is the term used to describe the process of synthesizing RNA from a DNA template strand.
Choice A is incorrect because a complementary strand of a DNA sequence refers to the strand that is complementary to the original DNA strand.
Choice B is incorrect because replication fork formation refers to the process of separating the two strands of DNA during replication.

Correct Answer is C
Explanation
Granzymes are a family of serine proteases that are stored in and secreted from the cytotoxic granules of cytotoxic T lymphocytes (CTL) and natural killer (NK) cells.
They work in synergy with perforin, a pore-forming toxin, to induce apoptosis in target cells.
Perforin is necessary for the delivery of granzyme B to the target cell cytosol where caspase-dependent and -independent pathways to apoptosis are activated.
Perforins (choice A) are pore-forming toxins that work in synergy with granzymes to induce apoptosis in target cells.
Cytokines (choice B) are signaling molecules that regulate immune responses but do not directly induce apoptosis in target cells.
Interferons (choice D) are a type of cytokine that play a role in immune responses but do not directly induce apoptosis in target cells.
