Answer:
<u>Option- D: </u>Is the best choice to choose from the given options.
Now, let us explain the term Cell cycle in a more comprehensive way.
<u>As the cell cycle is controlled at three checkpoints.</u>
- The integrity of the DNA is assessed at the G₁ checkpoint.
- Proper chromosome duplication is assessed at the G₂ checkpoint.
- Attachment of each kinetochore to a spindle fiber is assessed at the M checkpoint.
Explanation:
The cell cycle is controlled by three internal checkpoints that evaluate the condition of the genetic information.
- <u>The G₁ Checkpoint</u>:This stage determines whether all conditions are favorable for cell division to proceed. The cell can halt the cycle and attempt to remedy the problematic condition, or the cell can advance into G₀ (inactive) phase and await further signals when conditions improve.
- <u>The G₂ Checkpoint:</u> The most important role of the G₂ checkpoint is to ensure that all of the chromosomes have been accurately replicated without mistakes or damage.
- <u>The M Checkpoint:</u>It occurs near the end of the meta-phase stage of mitosis. it determines whether all the sister chromatids are correctly attached to the spindle micro-tubules

Answer:
Proteins form without the use of any kind of genetic code. Errors in translation would affect many generations of proteins.
Explanation:
Answer:
C is the correct option. Storage of carbohydrates is not a function of the skeletal system.
Explanation:
Option A is correct because the skeletal system has parts like the red bone marrow in which red blood cells and white blood cells are produced.
Option B is correct because the bones store minerals like calcium and phosphorus.
Option D is correct because the major function of the skeletal system is to provide support and protect the vital organs of the body.
The skeletal system is not involved in storing carbohydrates. Hence, all statements are true except for statement C.
