Which of the following best describes the function of dynein proteins as mentioned in Figure 6.24 b ?

  • A: They serve as motor proteins that cause the bending movement of cilia and flagella.
  • B: They are cross-linking proteins that hold the outer microtubule doublets together.
  • C: They form the central pair of microtubules in cilia and flagella.
  • D: They regulate the length of the microtubules during assembly.

Explanation

Figure 6.24 b explicitly states that the outer microtubule doublets have "attached motor proteins called dyneins red in art ." This indicates their role in generating movement.
