Quiz on Epigenetics

What is the main focus of the article "Genetics is so last century"?

• The importance of DNA in determining traits

• The role of epigenetics in determining how we live and die

• The similarities between identical twins

• The history of genetic research

What does the article suggest about the relationship between epigenetics and diseases like asthma and cancer?

• Epigenetics has no impact on these diseases

• Epigenetics can influence the development of these diseases

• These diseases are solely determined by genetic mutations

• These diseases are not related to gene expression

What is the main focus of researchers in the field of epigenetics according to the text?

• Increasing computer power

• Identifying the on/off gene switching process

• Developing new proteins

• Mapping the human genome

What is the first step in gene expression?

• Translation into proteins

• Gene switching

• Reading the DNA

• Cell division

What do methyl groups do when they attach to DNA?

• Speed up the reading process

• Act as a molecular roadblock

• Unwind the DNA

• Create new genes

What is the role of acetyl groups in gene expression?

• They bind to DNA and stop gene reading

• They unwind the DNA, making it more accessible

• They create new histones

• They destroy methyl groups

What is the molecular equivalent of throwing a spanner in the genetic works?

• Gene expression

• DNA methylation

• Epigenetics

• Protein synthesis

What is the function of enzymes in the first step of gene expression?

• They create new DNA

• They zip along the DNA to read it

• They switch off genes

• They bind to histones

What can molecules from our environment, like methyl groups from our diet, affect?

• How our genes are interpreted

• The structure of our bones

• The color of our eyes

• The length of our hair

What is the effect of stress on gene interpretation according to the text?

• It can set up epigenetic roadblocks

• It can change the DNA sequence

• It can increase protein synthesis

• It can cause gene deletion
