Question

12. Which type of intermediate 1 point
filaments are found in the
nuclear envelope *
​

Answer 1

Answer:

Intermediate filaments are a primary component of the cytoskeleton, although they are not found in all eukaryotes, and are absent in fungi and plants. These filaments, which extend throughout the cytoplasm and inner nuclear membrane are composed from a large family of proteins that can be broadly grouped into five classes.

Explanation:

IF assembly begins with the folding of IF proteins into a conserved alpha-helical rod shape, followed by a series of polymerization and annealing events that lead to the formation of filaments roughly 8 to 12 nm in diameter.

Answer 2

⇒keratin and vimentin filaments attach to the nuclear envelope, apparently serving to position and anchor the nucleus within the cell.

⇒ intermediate filaments can associate not only with the plasma membrane but also with the other elements of the cytoskeleton, actin filaments and microtubules.
