2 Nuclear membrane

Question 1

Function

Answer 1

• Also referred to as Nuclear Envelope.
• Encases/Protects the genetic material inside the cell and the nucleus
• Small pores over the outside called nuclear pores regulate/allow macromolecules such as proteins, RNA, water, ATP, and some to move into amd out of the nucleus

Question 2

Structure

Answer 2

Made up of two bilayers of phospholipids.
The Nuclear membrane is separated into 2 parts: Inner Membrane and Outer Membrane: They act as barriers and prevent the of molecules between the nucleus and the cytoplasm.

Nuclear Lamina
Nuclear Pores

Question 3

Outer Membrane

Answer 3

The outer membrane works with the endoplasmic reticulum, transportation of protein, and are both covered in ribosomes as they are the locations of protein synthesis

Question 4

Nuclear Lamina

Answer 4

filaments that give structure and support to the nuclear membrane
They are found the perinuclear space

Question 5

perinuclear space

Answer 5

space between 2 membranes

Question 6

Nuclear Pores

Answer 6

small holes cover the nuclear membrane and enable material to move in/out of the nucleus. They also connect the inner and outer membrane.

Question 7

Found? Why?

Answer 7

• They are found in all Eukaryotic cells

- The Membrane surrounds the nucleus and protects the DNA from substances that may enter from the cytoplasm
