    I just wish I had a longer lifetime (I just turned 80) because I am always discovering new things I would like to know something about, and the above subject is another! I had never heard of what she is talking about. So I was glad to find out there's a book that will try to enlighten what the lecturer was talking about.

    I'm here after reading her book "The Epigenetics Revolution" to learn about possible updates in the field since it came out a few years ago. I would highly suggest the book to anyone as I had no background knowledge other than high school Biology and yet every chapter would blow me away.

    The 8 proteins are histones and form a protein complex known as a histone octamer, which is spool shaped (marshmallows were used in the demonstration). The 8 proteins in the histone octamer are actually 2 copies of 4 proteins, H2A, H2B, H3 and H4. DNA wraps around the histone octamer known as a nucleosome and they form chains like beads on a string making up chromatin. A nucleosome can be defined as a small length of DNA wrapped around eight histone proteins. The key difference between chromatin and nucleosome is that chromatin is a whole structure of complex DNA and proteins while nucleosome is a basic unit of chromatin. The beads on a string make up something called euchromatin or open chromatin that is enriched in genes and active under transcription (transfer of genetic instructions) which is why it is so important in epigenetics and changes in the phenotype (physical traits- e.g. appearance).

    I scored rotten childhood, alcoholism, diabetes, 40yrs depression. My parents died 2012. I went outside and stood in the sun. Instant relief then happiness. Counselling and diagnosed as having aspergers (3yrs old emotionally top 2% computational brain). I took up Zentangling Art and I am still changing & growing. It took 20 yrs after MtDna test for me to find a living relative and I discovered that 5 gens back my ancestor came from Sweden who was a Sami. I then discovered I had inherited characteristics from that cultures but not in the same configuration. I bought a good copy of the I Ching and asked HOW I could bring information from the MtDna into my conciousness. The answer was hexagram 19. It told me not to think about it or ask another question and when I asked another question I was told to not do that again. This is simplified. The overall answer was that the answer was approaching. Sooooo... I bought a book on epigenetics, wrote to a scientist and I find your teaching style that puts the text books I am reading into context. I am 72 and am like a teenager. THANK you so much.

    Her explanation about stress and childhood experiences is interesting. I was very fortunate because I had a pretty stable, happy childhood with a protective father who thought I was a piece of gold and a loving mother who was a great nurturer. Even though I was overweight and constantly bullied, I retained my happiness and confidence that has allowed me to be successful in my career and personal life. I am married to a great person, but have noticed that he is usually depressed and insecure. His sister has finally admitted that out of 6 siblings, he was given the least amount of attention and praise and was often criticized. This was needed information for me as his spouse because I can now understand why he rather that I remain overweight. When I lost most of my weight, my husband would exhibit jealousy and insecurity. He would retreat into his den, and not talk to me. Now that I have lost my mobility, my husband seems happy which I find hurtful, but with theory, I have learned that he feels empowered because he feels no one will find me attractive and he can now be the only person I can depend

    🪄✨ Made with SummarizeYT
    0:49 - The human genome sequence was first released in 2001, causing a huge hoopla.
    2:03 - Epigenetic phenomena have been known for a long time but were not given much attention.
    3:00 - Laboratory mice with the same genetic background can have different weights due to epigenetic factors.
    5:01 - Gender in crocodiles is determined by the temperature at which the eggs develop, not genetics.
    6:01 - Different cell types in our body have the same DNA code but exhibit different characteristics.
    8:08 - Epigenetics plays a crucial role in gene expression and can be influenced by external factors.
    12:00 - Epigenetic modifications can switch genes on and off, leading to different gene expressions.
    14:00 - Epigenetic modifications can be compared to different flavors of jelly tots, introducing flexibility in gene expression.
    16:15 - Epigenetic modifications can also compact DNA, permanently switching off gene expression.
    17:27 - Epigenetic modifications can go wrong and contribute to diseases like cancer and diabetes.
    19:01 - Children who have experienced abuse or trauma in their childhood are more likely to develop chronic diseases later in life.
    20:07 - Epigenetics can influence what happens in organisms without altering the DNA sequence.
    20:42 - Baby rats that are loved and cared for by their mothers have low levels of stress hormones.
    22:03 - Epigenetic modifications in rats can be passed down from generation to generation.
    24:01 - Epigenetic information is necessary for mammalian reproduction.
    26:41 - Epigenetic changes can result in significant differences in physical characteristics, as seen in agouti mice.
    30:03 - Mice can learn to associate a smell with something negative, and this fear response can be passed on to their offspring.
    31:43 - Lamarck's theory of acquired characteristics is not entirely accurate, but epigenetic changes can be influenced by the environment.
    34:01 - Trauma experienced by male mice can be passed on to their offspring.
    35:05 - Epigenetic changes can affect the offspring's physical characteristics, as seen in the experiment with female mice.
    36:03 - Identical twins can have different outcomes due to epigenetic changes.

    This is EPIC!! Lamarck is partly vindicated, but that's the least of it. We are more "adjustable" than we realized before, and some of these adjustments can be passed on to the next generation. LOTS to think about, even for the ordinary person in the street who wants their offspring to be healthy and talented.
