All the following statements about destruction of cyclins are true EXCEPT: ubiquitin targets Cdks. destruction is carried out by
ZanzabumX [31]

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.

garik1379 [7]

Answer:

The correct answer is- A) two, B) yes, the number is the same as monosaccharides.

Explanation:

There are three atoms are present in a molecule of water which includes two atoms of the hydrogen and one atom of the oxygen. The hydrogen atom is two times larger in the number of the oxygen atom in a single molecule of the water.

In monosaccharides, the ratio of the atoms of carbon, hydrogen, and oxygen is 1:2:1 which means one hydrogen atom would be twice in the number of the carbon and oxygen atoms in a single molecule of monosaccharide molecule.

Thus, the correct answer is - A) two, B) yes, the number is the same as monosaccharides.
