As usual perfect!! I think, however, there is a small mistake. At the G2 phase, the text says: "once the chromosomes are replicated and the chromosome number doubles, the cell enters the G2 phase". I think the chromosomes are already 46 (23 homologous pairs). Each of these chromosomes, however, has only one chromatid. Hence after chromosome replication in the S Phase, the number of chromosomes stays at 46 but the number of chromatids doubles (not chromosomes).
There is an error in the G2 phase text, "once the chromosome are replicated and the chromosome number doubles" the number of chromosomes stays the same they just get an extra chromatid.
@BUENO SERGIO P Bruh why did you start and finish your sentence this way bro. We all are here to learn, it is okay to make mistakes. Correct people kindly please
I had one question, the two chromosome joined together through the centromere is called chromatids in this lecture i.e a pair among 46 pairs of original and sister chromatids, but in the previous lecture the same structure is being referred to as a pair among the 23 pairs of chromosome. btw I found your videos quite interest especially the bond energy, hope you could do a playlist that sums up the concepts needed for an Intermediate in Biology to revise.
Sir thanks a lot. it's very informative 😍😍 I wish you can make just one point clear that the meaning of the requirements and when should they be available
Only DNA Replicate in S phase but number of chromosome remains the same and only new DNA molecule forms the new chromatin fibres that further condense to form two sister chromatids which attach to each other through a centromere
i love u sir so much that i have found a very good teacher in my own home and that is you my respected sir. sir u r so intelligent and clear minded so sir request to u that only for the sake of Jesus just read the translation of the holy book quran i am sure that God will change u my respected beloved sir. sir please please aware yourself of islam. sir it is very peaceful religion. sir i just request to to study the biograpy of the prophet muhammad pbuh please please sir
i like how he goes back to summarize the lecture.. it makes the listener to get full understanding of what the lecture
Thank you !! I would like to request u to also upload your lectures on cell cycle regulation(cyclins,cdks,etc)
It is very useful to understand what is the difference between chromatids and chromosomes. Thank you in advance :)
You are a blessing, please keep making such informative videos! :)
i am preparing finals with your amazing videos..thank you so much..!
This Lecturer is the best lecturer in this site...You the best keep it up.
You are genius, sir. Your lectures are very helpful to students.
......India
Very informative, thank you for all your videos.
You're welcome Victor, thanks for watching! :)

You really make my life so easy ...thank you sir
a lucid and comprehensive explanation
Thank u so so much for this knowledge u are the best so far
Aren’t chromosomes formed during the prophase and only DNA duplicates and forms chromatin during the s phase?.... I think you got that wrong
Explained what noone else could in 9 mins
thank you best teaching
you sir are a life saver. you make exam cramming enjoyable ! do you have any lectures covering biodiversity ?
Maddie Al awesome Maddie! No I do not, sorry!
youre a G God bless your soul
Thank you so much,you simplified it very well.
Thank you, I will remember to donate, it's really help me.
What an amazing channel. Keep up with the great work
Sir plz make another video based on the regulation of cell cycle (cyclin, cdk etc.) ...... Thank u.. Love from india
hllo sir....i m preparing for NET exm...thnk uh for easy method...

really
@BUENO SERGIO P Bruh why did you start and finish your sentence this way bro. We all are here to learn, it is okay to make mistakes. Correct people kindly please
@BUENO SERGIO P Its okay, as long as you do not reproduce the same mistakes ;)
@BUENO SERGIO P relax
man you are very good, you might be better then khan academy, himself
joe xtz he actually is
I ❤️ u so much sir, u explain very very clearly from basic🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥,thank u sir

It is a mistake in the previous one. What you see in this video is correct.

you're the best
you are the best one
You are so helpful!

you are awesome. Thank you! Blessings.
MahReeNah Oz Thank you! :)
omg that’s bravooooooooo😢🎉
Cells that remain in the G0 phase, what happens with the organelles that have been produced (and the larger cell volume) in the G1 phase then?
انت رائع جدا ولكن لماذا عدد الاعجاب قليل انا محتارة في ذلك
i love u sir so much that i have found a very good teacher in my own home and that is you my respected sir. sir u r so intelligent and clear minded so sir request to u that only for the sake of Jesus just read the translation of the holy book quran i am sure that God will change u my respected beloved sir. sir please please aware yourself of islam. sir it is very peaceful religion. sir i just request to to study the biograpy of the prophet muhammad pbuh please please sir
thank you!!!
kindly upload some vedio on cellulose utilization in yeast...its vry urgent...bcz i couldnt find useful info about it...plz do it as soon as possible
Thank you sir
what happens if the cell does not have enough MPF factor? is there another equivalent of the G0 phase?
Progress,
Thanks :)
How about the regulation of the Cell Cycle
Super sir more Vedios give me sir
MPF is Maturation promoting factor not mitosis promoting factor
HI teacher, would you please tell me whether your lectures are high school or college level? Thanks
Please make lecture on cytoskeleton
hey man is it possible that g2 face doesnt need to synthesize any organalle or protein becoz the ones made during g1 face is enough
Shahariar Khan face or phase?
thank you
👍👍👍👍
Sir can I get notes from you?
Sir video has stopped at middle of the lecture.
10 q sir
Teacher, I cannot see the writen
really? put it on 1080p and make it full screen.
oh yeah! thanks teacher, I love you! you're the best!!
Rafael Coutinho hah thanks! hope you're enjoying the holidays :)
