A microtubule appears as a left-handed helix due to an approximately 0.9-nm stagger in the lateral contacts between adjacent pro
Olin [163]

Answer:

Th acceptable distance of tubulin monomers along a protofilament is : <u>A. 4nm</u>

Explanation:

MICROTUBULES are an important component of the cytoskeleton of eukaryotic cells. Its function is part of a structural role that helps define cell morphology, and also serves as an intracellular motor for some proteins such as kinesin and dynein.  

For the correct formation of the structures called microtubules to occur, a process called polymerization is required. In this process there is a head-to-tail junction in which the dimer junction between tubulines forms a structure called protofilaments and those protofilaments run along the microtubule. Then, the other process occurs in which, by lateral interactions between the structures mentioned above , the wall of The microtubule will be completed.

How did the Lumber industry contribute to the pollution in Sudbury (Located in Canada)

In the 1980s, the “Sudbury” became known as a unit of pollution, against which other industrial cities were measured. It’s now become known as a unit of restoration.
