1
New cards

Transcriptional control

if and how much of a gene is transcribed

2
New cards

Translational control

If and how much mRNA is translated

3
New cards

Post-translational control

changes to the protein after translation (becomes active/inactive, stable/unstable)

4
New cards
5
New cards

changes in chromatin structure

6
New cards

Positive vs negative regulation

Positive turns genes on (Activator)

7
New cards

Negative turns genes off (Repressor)

8
New cards

Transcription Factor

anything that assists with positive/negative regulation

9
New cards
10
New cards

Often recruit/repel RNA polymerase

11
New cards

Regulatory Element

Binding site for transcription factor

12
New cards

What are constitutive genes?

Genes that cannot be regulated ("always on")

13
New cards
14
New cards

harder for RNA polymerase to recognize and act on

15
New cards

What is a chromatin?

material that makes up chromosomes in eukaryotes

16
New cards
17
New cards

-comprised of histones organized into nucleosomes

18
New cards

-DNA + Histone = chromatin

19
New cards

How do chromatins help with regulation?

The more tightly packed the harder it is for RNA polymerase to recognise

20
New cards

Alternative splicing

Eukaryotic process where RNA "splices out" irrelevant introns, leaving only the exons

21
New cards

what is co-regulation?

process of expressing multiple genes in response to one stimulus

22
New cards

How does co-regulation occur in prokaryotes?

Prokaryotes use operons (long mRNA chain with multiple genes) and regulons (like eukaryotic regulation but under a specific name)

23
New cards

How do eukaryotes coregulate?

Can regulate multiple genes at the same time remotely (like a bluetooth connection)
