✏️ 3 Solved PYQs

What is the purpose of the lac operon ∈ E. coli? The lac operon is a genetic regulatory system that controls the expression of genes involved ∈ lactose metabolism. It allows the bacteria to turn on the genes necessary for lactose metabolism only when lactose is present ∈ the environment.
Describe the process of PCR. PCR, or polymerase cha∈ reaction, is a technique used to amplify specific DNA sequences. It involves the use of primers, nucleotides, and an enzyme called Taq polymerase to create millions of copies of a specific DNA sequence.
What is the difference between a stem cell and a progenitor cell? A stem cell is an undifferentiated cell that can differentiate into specialized cells, while a progenitor cell is a cell that has already begun to differentiate into a specific cell type.

🧠 The One Thing Most Students Get Wrong

Many students think that biotechnology is only used ∈ medicine, but it is also used ∈ agriculture, environmental science, and other fields.
