Cell Division

Question 1

Differentiation

Answer 1

Changes in structure and function to suit a specific purpose in the body,
-done with genetic tags
- the production of a master regulatory protein

Question 2

Central Dogma

Answer 2

explanation of the flow of genetic information

Question 3

Histones

Answer 3

Protien that DNA is wound around to pack it tightly, limits transcpription

Question 4

Heavy Methylation

Answer 4

Tightens DNA winding around histone

Question 5

Acetylation

Answer 5

Weakens DNA’s coil around histones by binding to tails

Question 6

Operator

Answer 6

Gate
Controls access of rNA polyermerase

Question 7

Operon

Answer 7

groups of genes
grouped by function in prokaryotes

Question 8

promoter

Answer 8

gate operator
determines if rNA polymerase is allowed to move to the operator depending on regulatory protien

Question 9

Regulatory Protien

Answer 9

gate guard
controls expression
dependant on signal molecule
detmermines if promoter allows it to Operator

Question 10

Signal molecule

Answer 10

tells regulator what to do
walkie talkie

Question 11

Negative Regulation

Answer 11

Reppressor, binds to regulatory protein and prevents it from binding to promoter

Question 12

Positive Regulation

Answer 12

binds to regulatory protein and allows it to bind to promoter

Question 13

Cytoplasmic Determinants

Answer 13

usually transcription factors
present in embryonic cytoplasm
from mother
unevenly distributed
cell differentiation
