The control system of the genome

Basics topics: cellular DNA is continuously damaged ; activity of cell cycle checkpoint is a part of the cellular response to DNA damage. 1 The control system of the genome and the passage through the cell cycle As you study the regulation of the cell cycle regulatory mechanisms discovered ties with a complicated network of signaling pathways , which is called the system of supervising the genome. 2 The cellular response to DNA damage .

Cellular regulatory systems. Feedback mechanisms and substrate-product relationship in the cell cycle

The correct sequence of events in the cell cycle progression is monitored by a complex molecular mechanism , wherein the anchor points serve as signal transduction pathways , both operated upon detection of disturbances in the assembly of cellular structures , and in the normal course of subsequent stages of interphase and mitosis. The system of these points in time starts and stops the key enzymes controlling the cell cycle , and any signals of structural disruption or damage following reactions converts blocking DNA synthesis or by inhibiting the initiation of cell division.

Cell cycle checkpoints: if we know Their molecular basis

Presented scientific silhouettes awarded the 2001 Nobel Prize in physiology and medicine ? Leland Hartwell , Paul Nurse'a and Timothy Hunt , the pioneers of molecular mechanisms regulating the cell cycle . Their research mainly due to the detection of protein serine- threonine kinases called cyklinozależnymi , due to the regulation of their activity by specific protein ? cyclins . These kinases subsequently proved to be essential for normal cell cycle progression . Classic has become the concepts introduced by Hartwell START cycle checkpoints .
