A Correct answer
Explanation

Cistron is a gene. It is a section of DNA that contains the genetic code for a single polypeptide and functions as a hereditary unit. Interferons are proteins made and released by host cells in response to the presence of pathogens. They allow for communication between cells to trigger the protective defenses of the immune system that eradicate pathogens. Intron is a non-coding DNA sequence within a gene that is initially transcribed into messenger RNA but is later snipped out. Prions are proteinaceous infectious particles.
