You May Know That Scientists Are Able to Synthesize New

Multiple Choice

You may know that scientists are able to synthesize new strands of DNA through a process known as PCR, which utilizes a DNA polymerase derived from bacteria. By repeatedly heating the reaction products to 70°C, researchers can create new DNA from a template DNA strand. What does this tell you about bacteria compared to archaeons?

A) that some bacteria can survive at higher temperatures compared to archaeons
B) that some bacteria can survive at high temperatures, although archaeons can survive in much hotter environments
C) that archaeons prefer colder environments compared to bacteria
D) that bacteria and archaeons can likely both survive at temperatures of 122°C
