Germination is a process where plants and other organisms emerge from gymnosperm/angiosperm seeds and start their growth. Gymnosperms are seeds that are not protected by an ovule. Angiosperms are vascular plants that grow fruit and flowers, which are protected by ovule. Sprouting of a seedling from a seed is an example of germination. Fully developed seeds contain an embryo, that store food reserves and are wrapped in the seed coat. Some factors of successful germination include water, oxygen, temperature, type of soil, and light intake.

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.
