Question

Secretion vector is a kind of _______________

• A. Cosmid vector
• B. Plasmid vector
• C. Expression vector
• D. Artificial chromosome

Answer 1

Answer:

C. Expression vector

• A secretion vector is a type of expression vector that is designed to direct the expression of a recombinant protein and its subsequent secretion out of the cell.

• Expression vectors are tools used in molecular biology to introduce a specific gene or DNA sequence into a cell, where it can be expressed and the protein product can be produced. Secretion vectors are a subset of expression vectors that include specific DNA sequences that encode a signal peptide. This signal peptide directs the protein to the secretory pathway, allowing it to be secreted out of the cell.

Secretion vectors are often used in biotechnology applications, such as:

1. Production of therapeutic proteins: Secretion vectors can be used to produce large quantities of therapeutic proteins, such as insulin or growth hormone, in a controlled and efficient manner.

2. Vaccine development: Secretion vectors can be used to produce vaccine antigens, which can be used to stimulate an immune response.

3. Basic research: Secretion vectors can be used to study the function and regulation of proteins in a controlled and efficient manner.
