I feel like i have got my dronacharya to learn genetics... Sir thankyou so much sir . Keep uploading about genetics,, there's a list of genetic test and etc etc things listed in harvard online courses kindly explain those not everyone is affordable to learn there. Please sir please. And please explain about base editing expt undergoing in Japan for genetic disease treatment

Question..... can anyone explain or give clarity on the following ... does any change to typical Purine & Pyrimidine, folate, B6 or B12 pathways during pre or early post natal periods result in heritable genetics that could be passed from that baby should they procreate in later life?
The level of the complexity of the body just went through the roof. Finding therapies and new drugs for diseases just became very very very difficult if genes are being turned on and off by almost any external factor.

Environmental Factors: Environmental exposures, such as diet, stress, pollutants, and lifestyle choices Developmental Processes: Epigenetic changes are crucial during development and can result from the sequential activation or inactivation of specific genes Disease and Pathological Conditions: Epigenetic alterations are implicated in various diseases, including cancer, neurodegenerative disorders, and autoimmune diseases.
I have a question that is making me sick. I thought that methylation should always be interpreted as a repressive mark. So, how is it that H3K4me3, H3K36me, and H3K79me for example could lead to gene expression}? thank you
DNA methylation is a fundamental epigenetic event associated with physiologic and pathologic conditions, including cancer. Hypermethylation of CpG islands at active gene promoters leads to transcriptional repression, whereas hypomethylation is associated with gene overexpression.

@@BiologyLectures thank you very much! I will check out the paper. So, there are histone's methylations that are repressive (like H3K9me3 or H3K27me3) and methylations that are permissive, right? Maybe it depends on context, signals, or that are made in different aminoacids? I will read the paper btw. Thanks again!
Thank you so much for this very clear explanation. 💯
you are most welcome. Wish you all the best
very clear and simple, thank you
Thank you very much 😊

Very helpful lecture plz make more such videos 😍😍
thank you. We will
Keep continue cover genetics at higher level
We will certainly cover more topics on advanced topics. Please feel free to suggest some if you have any. Thank you.
thankyou so much
You are so welcome!
thankyou so much sir,
You are most welcome 😊
Perfectly put!!!
thank you.
very good
Thanks you very much. please consider subscribing to support us.
One thing to add is that not only tails but also histone cores are modified.
You should redo your lecture with better acoustics. And a bit slower
Superb
Thank you.
Very well explained. Thanks a lot sir 😊
Most welcome

Excellent lecture 😃

Thank you so much 🙏🏼

Hello Sir, does epigenetic changes are reverseible?
Unlike genetic changes, epigenetic changes are reversible and do not change your DNA sequence, but they can change how your body reads a DNA sequence
The level of the complexity of the body just went through the roof. Finding therapies and new drugs for diseases just became very very very difficult if genes are being turned on and off by almost any external factor.
thanks for the great explaination ..... I just wanna ask about the resources you used plz as I want to go into further details ?

Epigenetics and methylation same? Thanks for clarification
In addition to methylation, epigenetics also contains histone modification.
Can you explain the causes of epigenetics....🙏
Environmental Factors: Environmental exposures, such as diet, stress, pollutants, and lifestyle choices
Developmental Processes: Epigenetic changes are crucial during development and can result from the sequential activation or inactivation of specific genes
Disease and Pathological Conditions: Epigenetic alterations are implicated in various diseases, including cancer, neurodegenerative disorders, and autoimmune diseases.

Does DNA methylation only prevent certain genes from being expressed ?
Not all genes are active at all times. DNA methylation is one of several epigenetic mechanisms that cells use to control gene expression.
Very hard to understand.
Please watch and rewatch again. Hopefully you will understand
Thank you
You're welcome
