However, a question remains: how does telomerase determine the number of repeats to add? In this review, I will discuss about how telomerase can monitor telomere extension using fission yeast as a model. I propose a model whereby the accumulation of the Pot1 complex on the synthesised telomere...
How does it affect you once you stop using it? Winstrol: Winstrol has been in the news for years. This drug has been linked to a series of scandals across multiple sports. Like most drugs, Winstrol has a variety of possible side effects and should only be taken at the advice of...
Briefly describe an experiment that could test the hypothesis that the catalytic component of telomerase is made of RNA. State the consequences for transcription by having operons. Describe and explain what is meant by transcription and translation...
When telomeres are too short, some cells turn into cancer. Cancerous cells have the ability to prevent their telomeres from getting shorter by activating telomerase. If telomerase makes cancer cells immortal, how would the administration of telomerase prevent normal cells from becoming cancerou...

cancer), and they lived 12.75% longer on average than normal mice, with an 8.4% increase in maximum lifespan.94 In a 2012 experiment adult and old mice (1 and 2 years old, respectively) were given gene therapy that produced telomerase (the presence of which prevents shortening of telomers...
3). The HAE expansion persisted until HAE passage 25–30 (~ 80 PDs), without induction of telomerase (hTERT) expression. Thus, upon telomere erosion, cells abruptly stopped propagation. Despite efficient proliferation, the characteristics of the differentiated airway epithelium were not consistent—...

Is telomerase a DNA polymerase? How are nucleotides related to amino acids? What is the role of DNA helicase during DNA replication? What is the importance of DNA polymerase? Why are nucleotides added to the 3' end? How does DNA replication begin? Why can't DNA polymerase work continuously...
