In this deep-dive video we discuss the DNA replication of telomeres, which are novelties for linear chromosomes, especially the eukaryotes. We understand the telomere structure, telomerase enzyme, and delve into the end replication problem. I focus on both leading strand and lagging strand DNA replication to ensure you get a complete understanding of the telomere replication issue. Throughout the video, we also make sure to discuss the entire process in context of various telomere-associated proteins, especially the Shelterin complex.

You deserve insane amount of appreciation. Because to create this video I cannot imagine how many papers you had to go through. Thank you so much for this because for higher studies this is exactly what one needs.

I see all your lectures to clear my concepts..You make very tough topics also simpler and easy to understand.I gave a doubt you mentioned during lagging strand telomere replication there is no.template for making new okazaki fragment.for d, e, f. Why? Cant d, e,f single strand DNA cannot serve as template?

Each new okazaki RNA primer is laid after 100-200 nucleotides. If "d,e,f" is less than 100 nucleotides, a new RNA primer is not laid. You may want to revisit Elongation ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ak0Iojc8LhU.html and Termination ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qu9-Dj-byCI.html for clarity on okazaki fragment maturation and how it connects to the telomere ends.
