There are no known motor proteins that move on intermediate filaments (IFs).
Harlamova29_29 [7]

Answer: The correct option is E ( Intermediate filaments are unpolarized).

Explanation:

Intermediate Filaments are usually associated with cells that can withstand mechanical stress which includes claws of animals, hair and makes up the dead remnants of the epidermal cell of the skin. Therefore without the supporting network of intermediate filaments, an epithelium remains intact but the cells are prone to damage by abrasive forces.

Intermediate filaments are so named because they are thicker than actin filaments and thinner than microtubules or muscle myosin filaments

The properties or characteristics of an intermediate filaments that explains the lack of motor proteins is as a result of its subunits which are elongated, not globular and are associated in an anti-polar manner. Therefore, the overall filament has no polarity, and therefore no motor proteins move along intermediate filaments

While mRNA strands are being created, a sequence is sometimes miscopied. What is the worst that could happen to a cell should th
kupik [55]

Answer:

The most appropriate answer would be The cell will not make functional proteins from that mRNA strand.

The amino acid sequence of the proteins is derived from the nucleotide sequence of the mRNA (messenger ribonucleotide).

If the sequence of mRNA is miscopied, it will change the sequence of amino acids of the protein.

Consequently, the protein may become non-functional.
