dentify all the false statements. 1. CDK's confer target specificity to cyclin / CDK activity. 2. Cyclins activate CDKs. 3. Only
one cyclin is required per cell cycle. 4. CDK's are destroyed by the ubiquitination apparatus. 5. The concentration of a CDK changes less than a cyclin during a cell cycle.
CDK's confer target specificity to cyclin/CDK activity-This statement is true because in the cell cycle cyclin-dependent kinases (Cdks) process signals that lead to cell division
Cyclins activate CDKs-This statement is true because cyclin is the regulatory subunit which binds to CDKs and activate them
Only one cyclin is required per cell cycle-This statement is false because there are many types of cyclins per cell cycle;for example G1 cyclins(Cyclin D and E),S phase cyclins(Cyclin A) and mitotic cyclin(Cyclin B)
CDKs are destroyed by the ubiquitination apparatus-This statement is true because degradation of CDKs occurs through polyubiquitination
The concentration of a CDK changes less than a cyclin during a cell cycle-This statement is true because during the cell division cyclins are periodically synthesised whereas CDKs concentration remains constant
The Himalayan mountain range and Tibetan plateau have formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today. 225 million years ago (Ma) India was a large island situated off the Australian coast and separated from Asia by the Tethys Ocean.
Atoms bound together and form molecules. Molecules are a little more complex than atoms. For example water is composed of two hydrogen atoms and one oxygen atom which are both gases. Properties of oxygen and hydrogen are completely different than water molecules.
