Epigenetics involves heritable gene expression changes without altering DNA sequence. Environmental factors like diet and endocrine disruptors can influence these epigenetic processes.

Area of Science:

  • Molecular Biology
  • Genetics
  • Developmental Biology

Context:

  • Epigenetics governs gene expression through mechanisms like DNA methylation and histone acetylation.
  • These epigenetic modifications are crucial for cellular inheritance and organismal development.

Purpose:

  • To introduce epigenetic reprogramming in embryonic development and gametogenesis.
  • To review environmental impacts on epigenetic processes, including transgenerational effects.

Summary:

  • Epigenetics studies heritable gene expression changes without DNA sequence alteration.
  • Key mechanisms include DNA methylation and histone modifications (e.g., acetylation).
  • Environmental factors such as diet and endocrine disruptors can induce epigenetic changes.

Impact:

  • Understanding epigenetic reprogramming is vital for developmental biology.
  • Environmental influences highlight the potential for transgenerational epigenetic inheritance.
