Nuclear Envlope

Question 1

Lm

Answer 1

Basophilic line having chromatin on its inner surface and ribosomes on its outer surface

Question 2

Em

Answer 2

Double membranous which is 2 membrane units separated by perinuclear space and interpreted at nuclear pores
Outer membrane is rough and granular as it has poly ribosomes attached to it and continues with rer
Inner membrane is fibrils continues with peripheral chromatin in nucleus
And has lamins to stabilize it

Question 3

Nuclear pore complexs

Answer 3

Interruption of nuclear membrane where outer and inner membranes fuse to form and octagonal ring opening
Formed by 39 nucleoporins proteins
Nuceloporin filaments extends into cytoplasm and nucleus

Question 4

Function of pore

Answer 4

Transport proteins to nucleus
Export rrna and protein subunits of ribosomes by carrier proteins to cytoplasm
