<span>The smallest unit of geologic time is epoch.</span>
<span>Sodium atom has 11 electrons
The Na+ ion has a + charge because the atom has lost 1 electron
Therefore number of electrons = 10</span>
In pcr, it is important to use taq dna polymerase, as opposed to other dna polymerases. this is because taq is capable of synthesizing dna AFTER EXPOSURE TO 94° C.
Taq polymerase is a thermostable DNA polymerase. This means that it can withstand high temperature and is ideal in synthesizing DNA during PCR.
Taq polymerase under certain temperatures
1) optimum temperature for activity<span> is 75–80 °C,
2) with a </span>half-life<span> of greater than 2 hours at 92.5 °C,
3) 40 minutes at 95 °C and 9 minutes at 97.5 °C,
4) can replicate a 1000 </span>base pair<span> strand of DNA in less than 10 seconds at 72 °C</span>
Answer:
D) molecules diffuse through transport proteins.
