1

Eukaryote Characteristics

- Nucleus

2

Prokaryote Characteristics

- No nucleus

3

What is asymmetry?

- Part of stem cell renewal where the daughter cells from same replication have different fates.

4

What is methylation?

- Altering of gene expression (shape) by adding a methyl group to cytosine

5

What are non-muscle cells?

Cells that have actin in their cytoplasm and nucleus.

6

What is cytosine?

Amino acid part of a DNA gene that receives a methyl group during methylation.

7

What is a capsid(virion)?

Protective covering of a virus that is removed when inside a host

8

What is the viral envelope?

Provides protections and host recognition that is squired from host cell during viral replication

9

What is group translocation?

Part of an active process in crossing into the cell membrane when the substance is chemically changed

10

What are stem cells?

Cells that develop into the whole organism

11

What are phospholipids?

Composed of a hydrophilic head and hydrophobic tail

12

What is the stem cell niche?

Micro environment that control stem cell renewal

13

What is the inner leaflet?

Position of phospholipids on the inside of the cell

14

What is actin?

Regulation of the physical state of the cytosol

15

What is the fluid mosaic model?

Movement of the phospholipid bilayer

16

What is peptoglycan?

Material that make up bacterial cell walls
