๐งฌ Epigenetics is a new field of biology that explores the additional factors at play beyond genetics.
๐ฅ Epigenetic phenomena involve genetically identical organisms exhibiting different traits.
๐ก Epigenetics reveals that factors such as environment and temperature can influence gene expression.
๐งฌ Epigenetics is the study of how a single DNA genome can lead to different outcomes.
๐ฅ DNA is like a script that can be amended, resulting in various cell types and traits.
๐ฌ Recent advances in epigenetics have provided explanations for how DNA functions in cells.
๐งฌ Epigenetics is the study of how genes are regulated and expressed.
๐ DNA wraps around cluster proteins, and one gene can be wrapped around multiple clusters.
๐ธ Epigenetic modifications can turn genes on or off, leading to changes in gene expression.
๐ก Epigenetic modifications play a crucial role in human health and disease, including certain types of cancer.
๐ฌ Misregulation of gene expression due to epigenetic modifications may contribute to chronic diseases like rheumatoid arthritis and type 2 diabetes.
๐ Childhood experiences, such as neglect and abuse, can have long-lasting effects on mental health and increase the risk of addiction and depression in adulthood.
๐งฌ Epigenetic modifications early in childhood can determine whether a rat becomes stressed or happy in adulthood.
๐ฆ Various animals, including stick insects, salamanders, and zebra finches, can reproduce through virgin birth.
๐งช Epigenetic information on eggs and sperm is necessary for the development of mammals, which is why virgin birth is not possible in mammals.
๐ญ Epigenetics can explain the differences in appearance and traits of genetically identical mice, such as the agouti viable yellow mice.
๐ท Alcohol can alter the transmission of epigenetic information between generations in mice.
๐ญ Epigenetic information is passed on from parent to child, influenced by the environment.
๐ธ Mice can pass on environmental responses to their offspring using epigenetics.
๐ฆ The concept of Lamarckism is challenged by the findings of epigenetic inheritance.
๐จโ๐งโ๐ง Offspring size is not influenced by epigenetic transmission from the father, but the mother's perception of the father's genetic quality affects the offspring's growth.
๐ฏโโ๏ธ Identical twins start diverging epigenetically as they age, leading to differences in gene expression and phenotypic variation.
๐ฑ Epigenetic modifications control various biological processes in plants, including flowering and coloration.
๐ Epigenetics plays a role in animal cloning and the development of phenotypic differences between worker honeybees and queen honeybees.
๐ Epigenetics is a fascinating field with much more to discover, and the speaker has written books on the topic.
