A Polypeptide chain is a sequence of amino acids that is the foundation for the basic structure of a protein
Cell transport is movement of materials across cell membranes. Cell transport includes passive and active transport. Passive transport does not require energy whereas active transport requires energy to proceed. Passive transport proceeds through diffusion, facilitated diffusion and osmosis. The purpose of the transport proteins is to protect the cell's internal environment and to keep its balance of salts, nutrients, and proteins within a range that keeps the cell and the organism alive.
Answer:
The enzyme that is responsible for this is the cyclin dependent kinase subunit of mpf
Explanation:
This enzyme is also known as cyclin dependent kinase subunit, CDKs. they are protein kinases and can function as cell cycle regulators. They have the power to modify different protein substrates that are useful for the progression of cell cycle. CDKs are inhibitors hence stathmin is inactivated by phosphorylation. They help to control cell divisions. DNA should not be damaged for cell to move from G₁ to the S phase.
Answer:
DNA is found in the nucleoid
