The concept of sustainable development is based on the ideas of sustainable forest management and is derived from the Brundtland Report (1987).

It is basically an organizing principle which states that the human developmental goals should be met by maintaining the stability of the natural systems so that the natural sources can be sustained for future use as well.

So,<em> sustainable development basically means that the present needs should be met without comprising the needs of future generations.</em>

Which of the statements regarding the cell cycle is true? Group of answer choices It is regulated by cyclins and CDKs. Different
MA_775_DIABLO [31]

Answer:

All of these choices are correct.

Explanation:

Cell cycle is the process of growth and division of cell. It comprises of interphase and mitosis. In interphase the cell grows, replicates its genomic content and prepares itself for division. In mitosis the division occurs.

Cell cycle is controlled by a group of kinases called as Cyclin dependent Kinases (CDKs). They act by phosphorylating their substrates. They are of various types like Cdk1, Cdk2, Cdk4 etc. They become active when they bind to a regulatory protein called cyclin. They are also of various types like Cyclin A, Cyclin B, Cyclin C etc. Level of cyclin and corresponding CDK increases and decreases according to the stage of cell cycle. For example in S phase of cell cycle concentration of cyclin A and E shoots up. CDK2 is able to bind to these cyclin molecules and hence it becomes active.

Cell cycle has major checkpoints where the condition of cell is analysed before it proceeds to the next stage of cycle. If any abnormality is detected, repair mechanism is activated or the cell is killed. Checkpoints do not allow cell cycle to proceed in damaged cells.

p53 is a tumor suppressor protein which can halt cell cycle when it detects some abnormality in cell. It usually acts in G1/S checkpoint (before the DNA replication starts in cell) and G2/M checkpoint (before the cell division begins). Hence, all of the above statements are true.
