Question

Desert temperature often varies between 0 to 50${}^o$C. The DNA polymerase isolated from a camel living in the desert will be able to synthesize DNA most efficiently at

• A. $0^{o}C$
• B. ${37}^{o}C$
• C. ${50}^{o}C$
• D. ${25}^{o}C$

Answer 1

Answer: (B)

${37}^{o}C$

The camels are the dessert animals which belong to the group of mammals. The mammals are able to maintain the temperature of the body constant. The body temperature is maintained optimum at 37${}^o$ C and this is the temperature at which all the reactions takes place with the optimum activity of the enzymes. So, the enzyme DNA polymerase will synthesize the DNA most effectively at this temperature.

Thus, the correct answer is option B.
