Thermostable DNA polymerases are used in PCR because they
a. bind DNA more efficiency than thermolabile DNA polymerases
b. do not have a proof-reading activity
c. are less expensive than E. Coli DNA Pol III
d. can survive at the high temperatures used to denature DNA e. are water soluble
Homework Answers
I believe the correct answer to be:
Option D) Can survive at the high temperatures used to denature DNA..
As the denaturing step in the PCR uses temperatures at 95 degrees which is very high for a normal protein at which a normal protein will be denatured but this thermostable enzyme retains its activity.
feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

1- Which are the differences between the PCR we used in the lab and DNA replication in human cells? A. PCR replicates specific DNA segments while in human cells all the DNA is replicated B. PCR uses high temperature to dissociate the DNA strands while DNA replication in human cells uses helicase C. PCR uses a high temperature resistant polymerase while the DNA polymerase from human cells would denature at high temperatures D. A and B are true E. A,...

According to Robert Trivers, why are men generally larger and more physically aggressive than women? Because women are more reproductively “valuable” than men, hence competition for mates is fiercer among men Because men invest more heavily in reproduction than women Because men secrete more testosterone Trivers’ theory does not speculate on the origin of the sex difference in size and physical aggression Although some women are interested in casual sex (short-term mating), research has suggested that there are differences in...
