Chapter 13, Problem 13.1CC
Cytoskeletal
Expert Solution & Answer
Summary Introduction
To explain: The advantages of using repeating structural elements to construct the cytoskeleton.
Introduction: Modularity in the cytoskeleton is the common feature observed in prokaryotes and eukaryotes. Repeating structural elements are used to construct the cytoskeleton. The repeating structures help in giving the body its overall shape and structure.
Explanation of Solution
The repeating structures present in the cytoskeleton can be visualized with the help of sophisticated microscopy techniques. Cytoskeleton assembly is reversible and modular in nature. Production and transmission of mechanical signals through sensory perception is the primary advantage of using repeating structural elements to construct the cytoskeleton.
These repeating structural elements can be used as epigenetic determinants by modifying cell movement and cell shape ultimately leading to the determination of cell fate and function.
