Question

The nuclear lamina is
A) the sac that holds the genetic material.
B) part of the nucleus that holds RNA.
C) a fibrous layer that lines the inner face of the nuclear membrane.
D) the site of protein synthesis.
E) a single loop of the endoplasmic reticulum.

Accepted Answer

The nuclear lamina is a fibrous layer found on the inner face of the nuclear membrane that provides mechanical support and helps maintain the shape of the nucleus. It is made up of intermediate filament proteins such as lamin, and is important for regulating DNA replication, chromatin organization, and gene expression. It is not related to the sac that holds genetic material, RNA storage, protein synthesis, or the endoplasmic reticulum.
