Question 1

epigenetics

Answer 1

way of modifying DNA without changing sequencing (how much or what is expressed)

Question 2

which is not a type of DNA mod
- DNA myelination
- histone modification
- base pair rebinding
- chromatin remodeling

Answer 2

• no base pair change

Question 3

what are the effects of DNA mods on chromatin and DNA

Answer 3

affects chromatin structure, therefor DNA accessibility

Question 4

how does methyl effect chromatin

Answer 4

inactivates chromatin

Question 5

What happens to global DNAm with age

Answer 5

decreases, but specific regions of DNA increase

Question 6

epigenetic drift

Answer 6

decrease in DNAm in regions that had high DNAm (and vice versa)

Question 7

how does HIIT affect DNAm

Answer 7

immediately decreases DNAm but increase in fat cells after 6 months of training

Question 8

Which environmental factor does not affect epigenetics
- diet
- nutrition
- weight
- actvity

Answer 8

weight

Question 9

epigenetic clock

Answer 9

amount of modification to DNA

Question 10

Is DNAm tissue independent or tissue specific?

Answer 10

both

Question 11

What predicts chronological age within 2 years?

Answer 11

DNAm

Question 12

epigenetic age acceleration

Answer 12

when DNA appears older than you
