What is Taq DNA polymerase used for? What is RNA polymerase? What type of molecule is DNA polymerase? Is telomerase a DNA polymerase? Which DNA polymerase has exonuclease activity? What is the role of RNA polymerase? How is DNA polymerase made?
The absence of telomerase in somatic tissues is thought to promote genome instability at initial stages of oncogenesis, favoring the emergence of cancer-associated chromosomal abnormalities; restablishment of telomerase activity is expected afterwards if long term cell cycling is to occur. In addition ...
What is telomerase in DNA replication? Explain how a mutation in DNA could result in its antibiotic resistance. Which enzyme will be produced in a cell in which there is a nonsense mutation in the lac operon? A mutation has occurred in the promoter sequence of a gene. Briefly explain what...

( D )6、Telomerase is a kind of: A. RNA polymerase B. DNA polymerase C. primerase D. reverse transcriptase ( B )7、In the classic model of the Lac operon, the operator A. is located downstream of the lacZ B. binds the lactose C. is located upstream of the promoter D. is able ...
21, 22 Telomerase activity may help to abrogate this change by adding telomeric repeats on to the end of chromosomes, but it appears that this only occurs in foetal livers.23 Four groups have studied the relationship between telomere length and ageing in humans.6, 24, 25, 26 In one of ...
It is still debated whether the disease activity of SLE represents a risk factor for PSVD progression towards clinically significant PH. If PH is absent, PSVD should be considered as a possible diagnosis in SLE patients with mild and persistent elevations in transaminases, GGT, and/or ALP [38...
What is the role of DNA polymerase epsilon? What does the Cas9 enzyme do to DNA when it binds to the DNA? Explain. What is the role of DNA polymerase delta? What is the role of the polymerase chain reaction in DNA or RNA sequencing? How does Telomerase bind to the DNA? Wh...
