Answer:
In immunology, an antigen is a molecule or molecular structure, such as may be present on the outside of a pathogen, that can be bound by an antigen-specific antibody or B-cell antigen receptor. The presence of antigens in the body normally triggers an immune response.
Mitosis is the correct answer
Answer: THEY ARE INVOLVED IN THE DISASSEMBLY OF THE NUCLEAR ENVELOPE
Explanation: The disassembly of the nuclear envelope is triggered by the cyclin‐dependent kinase at the onset of mitosis. At this point, Integral nuclear membrane proteins diffuse/move into the endoplasmic reticulum (ER) after nuclear envelope breakdown. The nuclear envelope reassembles around compact chromosome mass at late anaphase/telophase and the chromosomes condenses and become visible.
