How is the m checkpoint controlled
Web23. Eukaryotic chromosomes are thousands of times longer than a typical cell. Explain how chromosomes can fit inside a eukaryotic nucleus. The genetic material remains distributed in the nucleus, mitochondria, and chloroplast. The genome is present in a looped structure, thus it fits the size of the nucleus. WebThese checkpoints occur near the end of G 1, at the G 2 –M transition, and during metaphase (see figure below). The cell cycle is controlled at three checkpoints. Integrity of the DNA is assessed at the G 1 checkpoint. Proper chromosome duplication is assessed at the G 2 checkpoint.

WebThe cell cycle is based on three main checkpoints: - Phase G1 – DNA integrity and cell size. - Phase G2 – DNA damage and chromosome duplication. - Phase M – Attachment of kinetochore and a spindle fiber. The key role of checkpoint proteins is to detect DNA damage and send a signal to delay cell cycle advance until the damaged chromosomes ...
