People who have leukemia, a cancer that affects white blood cells, are often given Cytrabine. This drug inhibits the synthesis of DNA.
S-phase of cell cycle is most affected by Cytrabine because cytrabine interfers with synthesis of DNA and we know that in S-phase of cell cycle synthesis of DNA takes place.
In eukariotes, cells that have a neculeus, the dna is found in the neculeus, not the cytoplasim so that is false... I dunno if that is what u were asking...
According to the evolution theory, the first insects appeared about 400 million years BC in the Devonian Period.
