Answer:
ubiquitin targets CDKs
Explanation:
Cyclins are named such because they undergo a constant cycle of synthesis and degradation during cell division. When cyclins are synthesized, they act as an activating protein and bind to Cdks forming a cyclin-Cdk complex. This complex then acts as a signal to the cell to pass to the next cell cycle phase.
Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks). A lone Cdk is inactive, but the binding of a cyclin activates it, making it a functional enzyme and allowing it to modify target proteins.
Answer:
Frogs have smooth or slimy skin that is moist, whereas toads have thicker, bumpy skin that is usually dry. All toads are poisonous, while frogs are not.
Flowers and pollinating insects are examples of <span>coevolution. </span>
Answer:
returns to the left heart, completing the pulmonary cycle
Explanation:
DNA needs to replicate before cells divide to give the complete set of genetic instructions to its daughter cells, (or ensures that each new cell inherits all of the genetic traits of the parent cell).
Hope this helps! :D
