Question

(a) ‘H’ line

(b) ‘A’ line

(c) ‘M’ line

(d) ‘Z’ line

This question was addressed to me by my school teacher while I was bunking the class.

This question is from Locomotion & Movement in chapter Locomotion and Movement of Biology – Class 11

Answer 1

Correct choice is (c) ‘M’ line

Best explanation: The myosin filaments or the thick filaments are held together by the ‘M’ line. The ‘M’ line is present in the middle of the ‘A’ band or the anisotropic band or the dark band, and is thin and fibrous.
