Kinases. Kinases add phosphate to molecules, and the modification can serve as a "switch" to turn events in the cell on or off. CDKs or cyclin dependent kinases regulate the cell cycle.
Answer:
The correct answer is rRNA plays an important role during translation (protein synthesis) of mRNA.
Explanation:
Ribosomal RNA or rRNA are the RNA molecules which build up the site for protein synthesis known as ribosomes.
Ribosome synthesis takes place in nucleolus where two types of rRNA molecules associates with proteins, one in large subunit and one in the small subunit to form ribosomes.
These ribosomes physically moves along an mRNA molecule and catalyze the assembly of amino acids where rRNA molecules performs the catalytic steps of protein synthesis that is stitches amino acids together and makes up proteins.
Thus, rRNA plays an important role during translation (protein synthesis) of mRNA.

Answer:
Species could go extinct when their environment changed if they could not adapt to the change.
It would be the yew tree.
Yew (Taxus baccata) is a typical tree of churchyards, where some are thought to be well beyond 1,000 years old. Poisonous yew trees were planted in churchyards by the farmers to make sure that their animals didn’t stray into them.
