Question

short notes in actin filament​

Answer 1

Answer:

Actin filaments are the smallest cytoskeletal filaments, with a diameter of 7 nm. They are thin, relatively flexible threads that can be crosslinked together in different ways to form very different structures.

Actin monomers are called globular actinor G-actin. As their name suggests, they are fairly globe-shaped in structure. At the right concentration of monomers, they can polymerize head to tail to form filamentous actin or F-actin. F-actin threads associate with each other in a thin double-helical structure.
