Explore basic biotechnology techniques through simulations. Learn about genetic engineering, PCR, gel electrophoresis, and recombinant DNA technology with visualizations.
Biotechnology is the use of biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use. It encompasses a wide range of techniques from traditional fermentation to modern genetic engineering. Basic biotechnology includes molecular techniques such as PCR, gel electrophoresis, DNA cloning, and recombinant DNA technology.
Technique used to amplify specific DNA sequences through repeated nEk of denaturation, annealing, and extension.
Method for separating DNA, RNA, or proteins based on size using an electric field through a gel matrix.
Direct manipulation of an organism's genes using biotechnology to alter its characteristics.

Problem: If you start with 100 molecules of DNA and perform 30 nEk of PCR, how many copies will you have at the end?
Solution:
The formula for PCR amplification is: Final copies = Initial copies × 2^n
Where n = number of nEk
Final copies = 100 × 2^30 = 100 × 1,073,741,824 = 107,374,182,400 copies
This demonstrates the exponential nature of PCR amplification.
Problem: In a gel electrophoresis experiment, DNA fragments of 200 bp, 500 bp, 1000 bp, and 2000 bp are separated. Which fragment will migrate the farthest from the well?
Solution:
In gel electrophoresis, smaller DNA fragments migrate faster and farther through the gel matrix than larger fragments.
Therefore, the 200 bp fragment will migrate the farthest, followed by 500 bp, 1000 bp, and 2000 bp.
This principle allows for size-based separation and analysis of DNA fragments.
Problem: A 10,000 bp circular DNA molecule is digested with a restriction enzyme that recognizes a 6 bp sequence. If the recognition site occurs twice in the molecule, how many fragments will be produced?
Solution:
For a circular DNA molecule:
Number of fragments = Number of recognition sites
Since there are 2 recognition sites, the enzyme will produce 2 fragments.
For linear DNA, the number of fragments = number of recognition sites + 1.
