nuclear envelope
The _______________ is the two-layered membrane that encases the nucleus of a eukaryotic cell, separating the nucleus from the cytoplasm.
Nucleus
The genetic center of the eukaryotic cell is the __________.
is rich in ribosomal RNA
The nucleolus __________.
nucleolus
The round body that sits inside the nucleus of a eukaryotic cell and makes ribosomal subunits from proteins and ribosomal RNA is known as the
Chromosomes
are tightly coiled bundles of DNA and protein found in the nucleus of most living cells.
DNA
is the self-replicating material present in nearly all living organisms; it is the main constituent of chromosomes and the carrier of genetic information.
RNA
is used in all steps of protein synthesis and carries the genetic information of many viruses.
