Solution:
Cell-division control affects many aspects of development. Caenorhabditis elegans cell-cycle genes have been identified over the past decade, including at least two distinct Cyclin-Dependent Kinases (CDKs), their cyclin partners, positive and negative regulators, and downstream targets. The balance between CDK activation and inactivation determines whether cells proceed through G1 into S phase, and from G2 to M, through regulatory mechanisms that are conserved in more complex eukaryotes.
This is the required process through phosphorylation, Cdks signal the cell that it is ready to pass into the next stage of the cell cycle. As their name suggests, Cyclin-Dependent Protein Kinases are dependent on cyclins, another class of regulatory proteins. Cyclins bind to Cdks, activating the Cdks to phosphorylate other molecules.
Trisomy is the answer.
A trisomy is a chromosome abnormality in which a person has three copies of a particular chromosome rather than the expected two.
Trisomies can have varying effects on a person's health depending on which chromosome is affected by the trisomy. Some trisomies such as trisomy x have only mild effects whereas others such as trisomy 21 also known as Down syndrome result in health problems and development delays.
Many Trisomies can have fatal consequences such as trisomy 16 or trisomy 18 .They frequently cause miscarriages or loss of the baby shortly after birth.
