A) what are telomeres? b. are telomeres present in both prokaryotes and eukaryotes? c. explain why some cells have telomeres and others don't (base your explanation on the structure of the dna molecule and the directionality of polymerases).

A)     Telomeres are the caps at the end aspect of DNA that defend our chromosomes, which guards the end of a chromosome from corrosion.

B)       Telomeres only exist in eukaryotes, because it possesses the chromosomes from being tarnished by specific molecules in the cell.

C)      The Telomeres are known as to hold a capping function. Its principal mission in the eukaryotes is to defend the end of the chromosome from the DNA deprivation, its repair contrivance and the fusion with other ends. It is also inattentive in the prokaryotic cells because it has a circular chromosomes, therefore Telomeres are needed in their state.

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.
