**Title: Monitoring Protein Folding Over Time**

**Description:**
This study addressed how protein folding progresses over time. A graph is provided depicting the relationship between time and the portion of protein in its native folded state.

**Graph Analysis:**

- **Axes:** 
  - The vertical axis represents the "Amount Native" protein.
  - The horizontal axis indicates "Time."

- **Curve:** 
  - The curve starts at point D (low amount of native protein) and increases over time.
  - It shows a sigmoidal (S-shaped) curve, indicating an initial slow folding process, followed by a more rapid folding phase, and finally plateauing as the protein becomes fully folded.

**Points on the Graph:**
- Point A is at the top of the curve indicating the maximum native state.
- Point C is where the inflection point occurs, marking the point of fastest change.
- Points D and E indicate the initial stages of folding with low native protein.
- Point B on the time axis corresponds with the midpoint of rapid folding.
- Point F indicates the completion of the folding process over time.

**Question:**
Identify the time when all of the protein is native.

**Choices:**
- [ ] A
- [ ] E
- [ ] D
- [ ] F
- [ ] C
- [ ] B

The answer to the question is the point where the graph plateaus, indicating that all protein is folded, which corresponds with point A.

Expert Solution
Step 1

The proteins can be modified by different modifications and this modification can affect the function of the protein. The native structure is the structure of protein that is usually found in normal condition and it is the normal functional structure of protein.
