Gene Regulation/ Expression

Question 1

What does gene expression mean?

Answer 1

Cellular function

Question 2

What are the requirements for gene expression?

Answer 2

Necessary proteins must be synthesised at the proper time and place

Question 3

What are the stages of gene regulation?

Answer 3

Transcription
Post transcripted regulation
Translation

Question 4

What does epigenetic mean?

Answer 4

Heritable changes that do not involve changes in the DNA sequence

Question 5

What does post transcriptional mean?

Answer 5

Control of gene expression after the RNA molecule has been created but before it is translated into protein

Question 6

What are the chemical modifications of chromatin via histones?

Answer 6

Acetylation
De acetylation
Methylation

Question 7

What are the chemical modifications of chromatin via DNA?

Answer 7

Methylation

Question 8

What are the differences of methylation via histones and DNA?

Answer 8

DNA: on CCC mean there is no gene expression
Histones: lowers attraction so it unwinds therefore there is gene expression
