The unit membrane of nuclear envelope is about ----- thick. a) 75- 90°A b) 20-30°A c) 40 - 70°A d) 30-40°A |

Answer» bExplanation:The nuclear ENVELOPE consists of two lipid bilayer membranes: an inner nuclear membrane and an outer nuclear membrane.[4] The SPACE between the membranes is called the perinuclear space. It is usually about 20–40 nm wide.[5][6] The outer nuclear membrane is continuous with the endoplasmic reticulum membrane.[4] The nuclear envelope has many nuclear pores that allow MATERIALS to move between the cytosol and the nucleus.[4] Intermediate filament proteins called lamins form a structure called the nuclear LAMINA on the inner aspect of the inner nuclear membrane and give structural support to the nucleus.[ |
