Question

Skeletal muscles appear striated due to presence of two characteristic proteins in alternating dark and light bands. Which of the following is a correct match of the protein with its light refractive property and colour?

Answer 1

The correct option is (d).

Explanation:

Each actin (thin) filament is a polymerised protein made up of two 'F' (fiblous) actin strands helically wound to each other. Each 'F' actin is a polymer of monomeric 'G' (globular) actins. It is light in colour and shows isotropic property.
