AQA A-Level Biology. 3.2 – Cells Questions and Answers Already Passed Structure of Nucleus. 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. 2. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. 3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. 4. Chromosomes: protein-bound, linear DNA. 5. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures rib...

Nuclear parts of a cell o Nucleus: contains chromosomes, & regulates DNA of the cell. Defining structure of eukaryotic cells (they all have nucleus). Passes genetic traits between generations. Contains nuclear envelop, nucleoplasm, nucleolus, nuclear pores, chromatin, & ribosomes. o Chromosomes: thread like rods of DNA. Short deoxyribonucleic acid, DNA is the genetic material that stores information about the plant/animal. o Chromatin: DNA & Protein makeup chromosomes o Nucleolus: Proteins,...
