GCSE Biology - What are DNA Mutations? #67

[@hamzie1010]

The amount of time and effort in making each video makes me really happy. Not only are they high quality, but the facts are on point and precise. I am impressed. I hope to see more educational videos like these in the future. And I thank you for helping me through my GCSE's.

[@Cognitoedu]

Thanks so much! Really appreciate your support 🥳

[@ellamaibonetto5990]

this is absolutely perfect as a year 11 student whose preparing for my exams as on days with minimum motivation I can just watch these so thankn you

[@moon_vlogs873]

Really understood the topic in an easy way rather than making it complex. Thank you for explaining in a very easy way with extra info which teachers dont give in classes

[@briellejaner.5512]

The genetics topic is so confusing but these videos you guys are creating are so helpful and easy to digest! Thank you for all the hard work you put in into these drawings and the content it self! will you be making a speciationand natural selection video anytime soon?

[@Cognitoedu]

Thank you! Really happy to hear they’re useful!

Europeans have a genetic weakness when it comes to certain skin conditions, such as skin cancer and sunburns, due to their fair skin, light hair, and light eyes. People with these traits have less melanin in their skin, which provides less protection against harmful UV radiation from the sun. This makes them more susceptible to sunburns, skin damage, and an increased risk of developing skin cancer. Additionally, individuals with fair skin are also more likely to be deficient in vitamin D, as their bodies are not able to produce as much vitamin D from sunlight compared to individuals with darker skin tones. Vitamin D deficiency can lead to various health issues, such as weakened immune system, bone disorders, and increased risk of certain autoimmune diseases. Overall, individuals with fair skin, light hair, and light eyes may be more prone to certain health issues due to their genetic predisposition, but taking proper precautions, such as wearing sunscreen, protective clothing, and avoiding prolonged exposure to the sun, can help reduce the risk of these health problems.

Aw thankyou Danesha, we really appreciate your support 😍

i agree

[@PoisonelleMisty4311]

Furthermore, people of European descent may also lack certain genetic variations that provide resistance to certain infectious diseases prevalent in other regions, such as malaria resistance found in individuals from regions where malaria is common. Overall, genetic adaptations and variations can vary greatly among different populations, leading to differences in traits and susceptibility to certain health conditions.

Thanks for this masterpiece we realllyyyyyy appreciate ❤

[@emaanmuhammad3684]

thanks a lot for your effort, it really helped me. You make short videos but that helps a lot.

Thanks Emaan, glad you liked it! 😊

[@PoisonelleMisty4311]

Europeans or white people have weaknesses in specific genes that make them more prone to certain health conditions or mental illnesses such as heart disease, diabetes, and certain types of cancer. Additionally, some studies suggest that people of European descent may be more susceptible to conditions such as depression and anxiety. So the next time a white person tells and arab to go back to the desert just remember they are jealous and envious of their genetic resilience and strength. And white people who think they can make white genes stronger by only have kids within their race will likely perpetuate these genetic weaknesses within their own community.

Wouldn't a mutation in a sequence of amino acids not make a different protien but an unfunctional one?

[@Cognitoedu]

Well it depends on the type of mutation, and random chance. This is sort of the key point about how the different mutations impact organisms

[@joshm6202]

@@Cognitoedu Fair, but I still don't see why you put it up with proof for evolution.
