GCSE Biology - DNA Part 1 - Genes and the Genome #63

In this video we recap chromosomes and then explain what DNA is, what genes and the genome are, and how we can use them to track the migrations of early humans.

not me the night before my biology exam trying to understand the whole semester

[_setyourheartablaze_]

nothing is better than studying biology that isn't even in ur syllabus at 12:45 am when u have school the next day.

Have my GCEs in a month and there's nothing worse than starting on past papers and realizing you know nothing so I'm immensely grateful for this video. Gonna come back with an A* hopefully all because of you TYSM 😭

[chrissaved]

God bless all the team members in Cognito you guys are a blessing to many

not to sound nity picky but 3:38 misspelling of stranger as "strager" it caught me of guard and made burst into laughter.

You are literally a life THANK YOU SO VERY MUCH for doing all of this! A huge help honestly!

[dhmqmqi]

every time I have these massive panics about my science term papers ur videos just appear like a savior. I actually understood smth thank you so much. I'll be back with an A+ for bio

[ranudikolugala]

I never really understood DNA but this really helped, thank you

[heartsyun]

no cuz this actually made sm sense i was really confused abt this at first now i understand sm better thanks<3

[robhayward]

Thank you for explaining that most chromosome drawings are confusing as they show a cell undergoing mitosis and not in its normal state. Why do they do this, I have spent hours going around in circles as each chromosome seemed to contain 4 DNA strands when they don't normally.

[lucifersinclair]

Back again to say thank you for these wonderful videos❤️

[dfretr]

This video is very informative. I have a PPE coming up and this has greatly helped me understand the subject. Thanks

[PrakashMatthew]

Thank you for the lucid explanation :)

[cryingniko]

I’m watching ur videos (chem, physics, bio) one day before my science exam lol

[adhamahmed]

thank you for this video, i can now understand topic 6 now, i just now need to go over all of it now.
But could i ask a question?
So lets say my hand for example, made up of a bunch of skin cells, which all have a nucleus and DNA for protein synthesis. So one skin cell in my body is programmed to create specific chain of amino acids to make a protein, now will my all my skin cells on my hand produce different chains of amino acids or would they all produce the same exact chain of amino acids? or will they produce different amino acids every different cell?

[sanduni]

Thank you so much it really helped..anyone can understand it easily...great🤘❤🤘❤🤘❤😊

[Lovelyrosia]

This was really helpful since i had an exam about DNA and RNA and chromosomes

[Slenderman-zdtv]

Typo at 3:37, Strager's > Stranger's* 😅

[bkhfwbo]

3:08 Question: are red blood cells red blood cells because they produce the protein hemoglobin? Or do red blood cells produce hemoglobin? Any help appreciated!🙏
