Understanding Epigenetics

What are the two main factors that contribute to human differences?

• Cultural and social factors

• Economic and political factors

• Diet and exercise

• Genetic and environmental factors

What does DNA stand for?

• Deoxyribonucleic acid

• Deoxyribose nucleic acid

• Dioxyribonucleic acid

• Dioxyribose nucleic acid

How many letters are in the human DNA code?

• Three million

• Three billion

• Three thousand

• Three hundred

What is the role of epigenetic marks?

• They change the DNA sequence

• They are involved in protein synthesis

• They are chemical tags that regulate gene expression

• They are responsible for cell division

What is gene expression?

• The process of DNA mutation

• The process of DNA replication

• The process of cell division

• The process of translating DNA into proteins

Why is epigenetic research considered challenging?

• All of the above

• It is difficult to access relevant tissues

• It requires a large number of participants

• It is hard to determine the relevance of epigenetic marks

What tissues are commonly used in epigenetic research?

• Blood and saliva

• Skin and muscle

• Heart and lungs

• Brain and liver

What is the difference between intergenerational and transgenerational epigenetic effects?

• Intergenerational effects are temporary, while transgenerational effects are permanent

• Intergenerational effects are observed in animals, while transgenerational effects are observed in humans

• Intergenerational effects are genetic, while transgenerational effects are environmental

• Intergenerational effects impact only the first generation, while transgenerational effects impact multiple generations

What is the current evidence for transgenerational epigenetic inheritance in humans?

• Evidence for inheritance only in the first generation

• Evidence for inheritance in all generations

• No evidence for inheritance beyond three generations

• Strong evidence for inheritance beyond three generations

What happens to the epigenetic information during embryo development?

• It is duplicated

• It is reset and relaid

• It is completely erased

• It remains unchanged
