WebHydroxyurea (Hydrea; hydroxycarbamide) is classified as an antimetabolite. It is thought to be cell cycle-specific for the S phase of cell division. Hydrea inhibits the enzyme … S phase follows G1 phase via the G1/S transition and precedes G2 phase in interphase and is the part of the cell cycle in which DNA is replicated. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved. Pre-replication complexes assembled before S phase are converted into active replication forks. Driving this conversion is Cdc7 and S-phase cyclin-dependent kinases, w… Web15 apr. 2012 · Hydroxyurea (HU), an inhibitor of ribonucleotide reductase, prevents cells from progressing through S phase by depletion of deoxyribonucleoside triphosphates.

These techniques can be carried out in vitro and do not require removal from the culture environment. The most common type of chemical blockade is arrest-and-release, which involves treatment of a culture with a chemical block and subsequent release by washing or addition of a neutralizing agent for the block. While chemical blockade is …
