The PCR amplification process most frequently employs an enzyme known as Taq DNA polymerase.
Taq Polymerase, or Taq DNA polymerase, is a biological catalyst that helps nucleotides join together to form DNA. Taq polymerase is a protein that is 832-amino acids long and has a molecular weight of 94 kilodaltons. It is a homolog of the Pol I DNA polymerase that is found in <em>Escherichia coli</em> (<em>E.coli</em>) (approx). This enzyme can withstand temperatures up to 95 degrees Celsius for 40 minutes before reaching its half-life. At the ideal temperature of 72 degrees Celsius, the rate of nucleotide incorporation ranges from two to four kilobases per minute.
Polymerase chain reaction operates at a very high temperature. At this temperature, Taq polymerase is able to carry out its function efficiently.

Answer:
The answer is D. A 200-million-year-old fossil of a flying mammal.
1- to 4-year-old age group experiences the highest overall injury rate for any age group under the age of 15.
More children die from unintentional accidents each year than from any other cause. The rates of unintentional injuries are generally higher among male teenagers aged 15 to 19 years, youngsters from low-income homes, and people of colour. In remote locations, some injuries also happen more frequently.
Although these demographic risk factors cannot be changed, environmental and behavioural dangers, such as dangerous driving, drinking while intoxicated, swimming pools that are not fenced in, and homes without smoke detectors, can be successfully changed with the right techniques.
The three most frequent unintentional accidents that resulted in fatalities among children aged 0 to 19 in 1996 were drowning, motor vehicle occupant, and pedestrian injuries. Although rates varied, these mechanisms together accounted for more than half of all unintentional injury deaths among children and teenagers.
