WebS phase is the period of wholesale DNA synthesis during which the cell replicates its genetic content; a normal diploid somatic cell with a 2N complement of DNA at the beginning of S phase acquires a 4N complement of DNA at its end. (Recall that N = 1 copy of each chromosome per cell [haploid]; 2N = 2 copies [diploid].) Web14. apr 2024 · So, Phase I is the first human trial, which is looking for the right dose of the drug, what side effects we can expect, and we kind of look at how the drug is metabolized in the body. So, that’s the Phase I trial. The second one is Phase II, Phase II trial. Phase II trials are looking for efficacy, and how active this drug is in breast cancer. dd-wrt on linksys ea4500
