Answer:
When helicase mutations occur, problems in DNA replication are found. The helicases are proteins that open the 2 strands of DNA to initiate the duplication, they are responsible for breaking the hydrogen bonds between the two DNA chains, thus separating the chains, also they have the function of repairing DNA mutations, if there is mutation in the gene that encodes them, various functions will be absent in the cell.

The answer is A, a vaccine. This is why they are often given to children for prevention.
Answer:
c. Fungi
d. Yeast
Explanation:
Both fungi and yeast will be effectively removed by a 0.22 micron pore size filter.
<em>The size of microscopic fungi ranges from 2 to 10 microns while the size of yeast ranges from 3 to 4 microns in diameter. Hence, both organisms will be effectively filtered off by a 0.22 micron filter paper.</em>
The size of bacteria ranges from 0.2 to 2 microns while that of virus is in nanometer. Hence both cannot be effectively removed by a 0.22 micron pore size filter paper.
The correct options are c and d.
