For the ribosomes on nuclear envelope, what would be the proteins made here do?

Solutions

Expert Solution

The nuclear envelope(NE) consists of an inner and an outer membrane enclosing the perinuclear cisterna or perinuclear space.

The outer nuclear membrane is studded with ribosomes and continuous with the membrane of the rough endoplasmic reticulum (RER). Therefore, direct continuity exists between the lumen of the nuclear envelope and the rough endoplasmic reticulum. The outer nuclear membrane is engaged in protein synthesis and that de novo synthesized proteins are translocated in the perinuclear space.

Post-translational modifications on proteins may occur here because of the presence of oligosaccharide-trimming glycosidases.

Ribosomes are made of :

Some chromosomes have sections of DNA that encode ribosomal RNA, a type of structural RNA that combines with proteins to make the ribosome. In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome. The newly made subunits are transported out through the nuclear pores to the cytoplasm, where they can do their job.
