In 1994, telomerase activity was discovered in human cancer cell lines. Although telomerase is not active in most human adult cells, all cells do contain the genes for telomerase proteins and telomerase RNA. Since inappropriate activation of telomerase may contribute to cancer, why do you think the genes coding for this enzyme have been maintained in the human genome throughout evolution? Are there any types of human body cells where telomerase activation would be advantageous or even necessary? Explain.

Hey everyone, Let's take a look at this question Together, identify the tell America sequence. In humans. So in humans we have a very common sequence that is found within those telomeres. And that sequence is this and it is repeated several 1000 times and sometimes it can vary in length from 5 to 15 killer bases. And so that same sequence also comes from the RNA template, which is this, which we're able to see that same sequence from the telomeres that we have here. Which would mean that this is that tell America sequence found within humans. So that means that answer choice B is the correct answer because in humans we have this very common sequence that is often repeated several times. And so that is that Tell America sequence, which is answer Choice B. I hope you found this video to be helpful. Thank you and goodbye.
