Question

Which of the following sequences correctly lists in order the steps involved in the incorporation of a proteinaceous molecule within a cell?

a) Translation → Transcription → Protein folding → Vesicle formation
b) Transcription → Translation → Vesicle formation → Protein folding
c) Translation → Transcription → Vesicle formation → Protein folding
d) Transcription → Translation → Protein folding → Vesicle formation

Answer 1

The correct sequence is Transcription, Translation, Protein folding, and Vesicle formation, which is option d in the question. This sequence represents the typical pathway of gene expression and protein targeting within a cell.

Step-by-step explanation:

The correct sequence for the incorporation of a proteinaceous molecule within a cell is detailed in option d, which outlines the following steps: Transcription → Translation → Protein folding → Vesicle formation. Initially, during transcription, the DNA sequence of a gene is copied to create messenger RNA (mRNA). Then, translation occurs, where this mRNA is read by ribosomes to synthesize a protein. Afterward, protein folding takes place where the amino acid chain assumes its functional three-dimensional structure. Finally, vesicle formation occurs, in which the folded protein is packaged into a vesicle for transport to its destination within the cell, often to the cell membrane or for secretion out of the cell.
