Each axial filament is made up of fibrils identical in structure to a. cilia. b. pili. c. flagella. d. pseudopods.

C. Flagella

Explanation:

Axial filaments are the locomotory organs. They are found in the spirochetes such as Borrelia. Each axial filament is made up of fibrils which are similar to the flagella. These are originated from the periplasmic space of the cell. Periplasmic space is the space between the inner and outer membrane of a cell. It also helps in rotating the cell body. Axial filaments are made up o many endoflagella.  It is a special type of filament that arises from endoflagella. Axial filaments help the cell contraction in forward,  and backward direction like a screw.

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.
