Answer:
The arrangement of thin and thick filaments in myofibril.
Explanation:
Myofibril is defined as the basic rod like structure present in muscle cells. They are made up of long proteins including titin, actin, and myosin, and other proteins are helping them to hold together. The organization of these proteins are thin, and thick filaments which is known as myofilaments.
Thin filaments: Contains the actin protein which is coiled with filament nebulin.
Thick filaments: Contains the myosin protein. It is also known for force generation.
RNA viruses take control of a cellular enzyme to design a replication compartment on the cell's membrane filled with PI4P lipids. Those copies then can go on to infect other cells.
The answer would be D.
Answer C, I think. Hope to help :)
