epigenetics

what is epigenetics

• Epigenetics is the study of changes in weather patterns
• Epigenetics is the study of changes in computer programming languages
• Epigenetics is the study of changes in cooking recipes
• Epigenetics is the study of changes in gene expression or cellular phenotype that are heritable and do not involve changes to the underlying DNA sequence.

Which of the following is a mechanism of epigenetic change?

• Mutation in the DNA sequence

• Deletion of a chromosome

• Methylation of DNA

• Duplication of the entire genome

How can epigenetic changes be inherited?

• Through changes in the DNA sequence passed from parent to offspring

• Through the inheritance of acquired characteristics

• Through the replication of epigenetic markers during cell division

• Epigenetic changes cannot be inherited

What role do epigenetic changes play in human health?

• They have no impact on human health

• They can alter gene expression and contribute to diseases

• They only affect plant health

• They change the DNA sequence to cure diseases

How do histone modifications alter gene expression?

• By changing the DNA sequence

• By affecting the stability of the mRNA

• By influencing the DNA-histone interaction, affecting chromatin structure and gene accessibility

• By directly interacting with transcription factors

What is the role of non-coding RNA in epigenetics?

• It serves as a template for DNA replication

• It is involved in the direct mutation of genes

• It plays a role in modifying chromatin structure and regulating gene expression

• It has no role in epigenetics
