Epigenetics

What is epigenetics?

• The study of how behavior and environment change our gene expression.

• The process of DNA replication in cells.

• The analysis of genetic mutations in organisms.

• The examination of protein synthesis in living organisms.

How can diet affect epigenetics?

• Certain nutrients can influence the addition of methyl groups to DNA, impacting gene expression.

• Diet has no effect on gene expression.

• Only carbohydrates affect epigenetics.

• Proteins are the only nutrients that influence DNA.

What is the difference between genotype and phenotype?

• Genotype refers to the observable characteristics, while phenotype is the genetic makeup.

• Genotype is influenced by the environment, while phenotype is the genetic makeup.

• Genotype refers to the genetic makeup, while phenotype is the observable characteristics influenced by the genotype and environment.

• Genotype and phenotype are the same and can be used interchangeably.

What is the significance of epigenetics in development?

• Epigenetics is responsible for the physical structure of DNA.

• Epigenetics plays a crucial role in cell differentiation and development by regulating gene expression.

• Epigenetics has no impact on gene expression.

• Epigenetics only affects adult organisms, not during development.

True or False: Gene expression has a change in ATGCs.

• True

• False

• Sometimes

• Rarely

What is an epigenome?

• A multitude of molecules (chemical compounds and proteins) that tell the genome what to do.

• A type of genetic mutation that alters DNA sequences.

• A collection of genes that are expressed in a cell at a given time.

• A process that permanently changes the DNA structure.

How do epigenetic changes relate to disease?

• Epigenetic changes have no effect on gene expression.

• Epigenetic changes can contribute to the development of diseases such as cancer by altering gene expression.

• Epigenetic changes only affect physical traits, not diseases.

• Epigenetic changes are reversible and do not influence disease progression.

Define DNA methylation.

• A process by which methyl groups are added to the DNA molecule, affecting gene expression.

• A method of DNA replication that occurs during cell division.

• A technique used to sequence DNA for genetic analysis.

• A form of RNA modification that regulates protein synthesis.

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

• Non-coding RNA can regulate gene expression and contribute to epigenetic modifications.

• Non-coding RNA is involved in protein synthesis.

• Non-coding RNA has no role in gene regulation.

• Non-coding RNA only serves as a template for DNA replication.
