DNA, Genes and Chromosome (No confusion).

[@girohead]

Thank you for those who wish they studied this, let alone wish such presentation tools were available.

[@ojd3708]

23 pairs Chromosomes are present in the cell nucleus. When examined closer, the chromosome is made up of a double helix DNA strand wrapped around histones( proteins)

[@zinnea9825]

Thanks 😊

[@Dark_007-z5o]

Thank you so much for making such a useful video It helps lot to understand the concept.

[@XploreBio]

Happy to make these videos.

[@yashvikudrigikar8943]

This video answered all of my complicated questions...thank you so much!

[@XploreBio]

Thanks..

[@ananalyticalhuman]

Awesome video!
Really clear concepts!
Most important video in entire RUclips

[@XploreBio]

thanks..

[@lukanyomakhabane2667]

Thank you so much man! One last question, how many chromosomes are found in fungi?

[@XploreBio]

Different fungi have different chromosome count. For example fission yeast (Schizosaccharomyces pombe) have 3 chromosomes while budding yeast (Saccharomyces cerevisiae) have 16. Good luck

[@fsg269]

Do each chromosome contain some part of DNA or every chromosome contains full copy of DNA within it?

[@Bry_zpt]

ty u helped so much and tomorrow I have a test about this

[@XploreBio]

thanks

[@khushi.92]

wowwwwww sir what a fabulous channel......every biology student need this information..

[@XploreBio]

thanxx

[@studyvibes3034]

Cells,nucleus,chromosomes,dna,histone protein,genes,nucleotides ..
Is the sequence correct sir?

[@XploreBio]

Yes. histone proteins are separate.

[@arshinaimran3235]

This video answered all my questions.

[@XploreBio]

Thanks very much.

[@abhaadhikari809]

It is crystal clear info thanks :)

[@XploreBio]

Thanks

[@omjanmeshrout3678]

Sorry i m wrong I mistakened .
You R absolutely correct .

[@XploreBio]

Check again.

[@omjanmeshrout3678]

I m sry u r correct.

[@neon9163]

70 Earth to Sun trips are not equal to 150 million km as one trip from the Earth to the Sun is 151.5 million km. By = 150 million km, you may have meant that one trip is that amount but it seems like 70 trips is that much. Also as per my calculations, the length of all DNA in a human body can go up to slightly above 107 trips from the Earth to Sun(One way)

[@neetamayavat5791]

Thanks so much , it helped a lot

[@venkateshnimma9394]

So many doubts cleared, thanks bro 👍👌

[@XploreBio]

Most welcome..

[@lukhanyomakhabane4238]

Why do we have genes located in chromosome 1, 2, 3 ,4 etc...how many chromosome does e.g fungi have... isn't that genomic DNA wrapped around histones to make chromosome unit...why then in some cases you would find people saying a gene is located in chromosome 1 or 3 or 5 of the genome? Help me I am confused here, I am new in this field.

[@XploreBio]

Now you know that genes are nothing but DNA fragment which is packaged as chromosomes. And different organisms have different number of chromosomes. Also, some genes are single copy and located on specific chr. while there are multicopy genes which lie on different chr. It is just a chance or evolutionary thing that which gene will lie on which chr. and in how many copies.
Hope this would answer your query.

[@lukhanyomakhabane4238]

@@XploreBio Thank you!

[@joyshree2984]

Thank you for clearing it.....

[@साहिबसिंह-ब4ज]

Nice explanation sir

[@tapascreation1087]

It is a good animation

[@ramjemanish]

Very well explained Sir

[@rainabanerjee7451]

Thank You Sir, it really cleared my concepts.

[@XploreBio]

Thats my moto to help researchers and students..Good luck.

[@ramasankargupt8460]

It's my pleasure

[@hayhey1777]

Thank you so much sir

[@XploreBio]

What a nice video and nicely 👌 explained

[@XploreBio]

Thank you

[@benitatobias1970]

You made it all clear.. thank you🙃🙃

Welcome

[@factsaboutalien623]

Your explanation is great Sir

Bhai, tnq

[@SauravUPSCAspirant]

A total of 23 pairs of chromosomes (and not DNA) are found in a human cell

[@XploreBio]

Please refer Chapter 2 of Book: Mapping and Sequencing the Human Genome. National Academies Press (US); 1988.
It says:
"The diploid human genome is thus composed of 46 DNA molecules of 24 distinct types. Because human chromosomes exist in pairs that are almost identical, only 3 billion nucleotide pairs (the haploid genome) need to be sequenced to gain complete information concerning a representative human genome. The human genome is thus said to contain 3 billion nucleotide pairs, even though most human cells contain 6 billion nucleotide pairs."
Hope this helps. Thanks.

Hard to hear

[@prakharsrivastav6665]

book ki hi reading karni hoti to mai utube pe kyu aata

xD

[@ranjanamanure2041]

Sir only you teach proparly and sufficiently

[@XploreBio]

Thanks..good luck

[@giftivieogbomon2016]

Try to make your voice more clear or add subtitles, i couldn't really understand because of ur accent

[@XploreBio]

thanks for honest suggestions. from now on i will add subtitles. changing my accent would affect other audience. thanks.

[@MShafikhan-zc8vg]

Can you tell the size of each chromosome

[@XploreBio]

It varies with species and cell cycle stage.

[@factsaboutalien623]

Make more videos

[@XploreBio]

Will definately..

[@ranjanamanure2041]

Sir next time explain chromosome
