Question

double-clicking on the table. 8. starting with instructions from the factory manager (dna/chromosomes), create a flowchart to show how a protein is produced and shipped from a cell.

Explanation:

To solve this, we outline the protein production process:

Step 1: Transcription (Nucleus)

DNA (factory manager’s instructions) is transcribed into mRNA.
$$\text{DNA} \xrightarrow{\text{Transcription}} \text{mRNA}$$

Step 2: Translation (Ribosome)

mRNA is translated into a polypeptide chain (protein) at ribosomes.
$$\text{mRNA} \xrightarrow{\text{Translation (Ribosome)}} \text{Polypeptide (Protein)}$$

Step 3: Protein Processing (ER/Golgi)

• Rough ER: Protein is folded/modified.
• Golgi Apparatus: Further modification, sorting, and packaging into vesicles.

Step 4: Shipping (Vesicle Transport)

Vesicles carry the protein to the cell membrane (for secretion) or other destinations.

Flowchart Outline:

1. Nucleus (DNA) → Transcription → mRNA
2. mRNA → Ribosome (Translation) → Polypeptide
3. Polypeptide → Rough ER (Folding) → Golgi (Modification/Sorting) → Vesicle
4. Vesicle → Cell Membrane (Secretion/Transport)

Answer:

The flowchart follows: DNA (nucleus) → Transcription → mRNA → Ribosome (Translation) → Polypeptide → Rough ER → Golgi → Vesicle → Cell Membrane (for export).
