It is refreshing to listen to an instructor calmly and confidently share such an important group of lessons. Thank you so much for your videos. Although my students are middle school, these lessons taught them at the level they could comprehend and are gifted enough to fill in the gaps.
THANK YOU THANK YOU THANK YOU for posting videos about the new syllabus as well as the old one. Please keep doing what you do because you're an amazing teacher :)
These people teaches so well that you do not even need to write genetics like tough subject on paper. Thank you very much for uploading such videos and clearning our confsions.:)
Thank you for the first DNA/chromosome explanation video that included diagrams of proportions and where everything is located!! Not even my university class did as good of a job explaining it!
I love Alex he is better than my bio teacher and i cant survive without him also his voice is very soothing and makes me willing to actually listen to it
I can never make sense of genes alleles and chromosomes, this video really helped
I've used your videos to help me understand genetics and they have all been a massive help to me. The best videos I've watched. (and I've watched a lot) Thank you :-)
Dude, I've been looking for videos to explain these very basics but all they talk about is the DNS, so thanks for giving me a heads up on these things!
You're good at explaining and your talks have a good flow.
thankyou for this vid! better explaining than my bio teacher, now I fully understand this!
this was so helpful for my studying...thanks for posting!
Really very helpful.. Now i finally understood it.. :D :D Thank you Mr Lee.

Thank you this was really helpful :)
woot woot! perfectly explained, Thank youuuu
Alex Could I consider the gene as a type of application program? Like a C.N.C. program or some other type of computer program that does work or a specific task?
Hey, loved you video. Saw that you had 45 dislikes and decided to add one to make 46. All the best!
I like the teaching it helps alot
Awesome video!
Thank you for the video :)
thanks bro nice vid
GREAT VIDEO...............
YOU ARE JUST AMAZING. THANK YOU VERY VERY VERYYY MUCH
its a very good video
thank you this was so mega helpful
What don't understand is; what determines the division point from one gene to another in a chromosome? How do you know that it isn't just one long gene in a chromosome rather than 20 genes in a chromosome?
Thank you so much, i am currently getting my Master's degree online and your video is helping me understand the science of gene and the terminology that I was not able to understand with PowerPoints and text alone. Thank you! Do you have anything on the Chromatin Structure?? My degree is in Nutrition and the class that I am having most difficulties in is Nutrigenetics and Nutrigenomics ......Thanks in Advance....
Wt is Quinto gene?
Thank you sir
very nice.. thanQ for the video :-) alex lee
thx for the explenation man. I would like to add that 1 chromosome contains about 2000 genes
can you please share your slides with me?
is there a first video to this
awesoooooome!!!!!!!!!!!!!!!!! ;) totally cool
Thanks, but sources and references would be nice for those that would like to double-check and/or pursue this topic further. Also, sources and references are just good form and respectful of the authors of those sources and references.
Thanks

Who needs Mr Johnson when we have online smart teachers.....
It was when I saw this vid that I got it when it comes to alleles. Same as a gene, just different forms. Gene X is for hair colour. Gene X has different versions called alleles. Same as: Gene X is Rice. Gene X may be white rice, brown rice, yellow rice, but its still rice.
