Genetic Engineering

Overview

Pioneering Molecular Innovation Through Genetic Manipulation

Genetic Engineering focuses on the direct manipulation of an organism's genes using biotechnology to modify biological functions, improve cellular traits, and construct novel synthetic bio-systems.

In this program, students immerse themselves in modern molecular techniques—including gene cloning, vector construction, CRISPR-Cas genome editing, and genetic circuit design. By executing hands-on experimental pipelines and analyzing recombinant expression, participants build competitive research portfolios for elite university admissions and biotechnology careers.

Selected Topics

Gene Cloning & Expression Vector Construction

Students perform restriction enzyme digestion, Gibson assembly, and plasmid transformation to construct functional recombinant DNA vectors for targeted bacterial expression.

Genome Editing via the CRISPR-Cas System

Explores sgRNA design, Cas9-mediated double-strand break induction, and non-homologous end joining (NHEJ) targeted gene disruption in model organisms.

Gene Expression & Quantitative Functional Analysis

Investigates transcriptional regulation and protein yield using RT-qPCR, Western blotting, and reporter gene fluorescence assays across varying induction states.

Synthetic Biology & Genetic Circuit Engineering

Focuses on assembling modular genetic parts (promoters, riboswitches, terminators) to build logic gates and self-regulating biological sensors.

Recombinant Protein Biosynthesis & Purification

Guides participants through affinity tag chromatography and SDS-PAGE quantification to harvest purified recombinant enzymes from engineered host cultures.

Plant Genetic Transformation & Metabolic Engineering

Introduces Agrobacterium-mediated gene transfer to introduce beneficial metabolic traits and stress-tolerance phenotypes into plant tissue models.

Sample Project Design

CRISPR-Cas9 Combined with Homologous Recombination/Recombineering

In this flagship research project, students design custom single-guide RNAs (sgRNAs) and utilize CRISPR-Cas9 combined with homologous recombination/recombineering to precisely edit a targeted non-essential marker gene in E. coli, quantifying editing efficiency and resulting cellular changes.

Research Question

How does sgRNA targeting efficiency influence Cas9 double-strand break precision, recombineering efficiency, and functional reporter suppression in bacterial cells?

Laboratory Activities

Students execute hands-on experimental protocols, including:

Designing complementary sgRNA oligonucleotides using bioinformatic CRISPR tools.
Ligating sgRNA inserts into Cas9 expression plasmids via restriction-clone assembly.
Preparing competent bacterial cells and introducing CRISPR constructs alongside donor DNA via electroporation/heat-shock for recombineering.
Selecting transformants by antibiotic resistance followed by colony PCR and sequencing to identify successfully edited clones.
Verifying target loci modifications across single colonies via colony PCR and Sanger sequencing.
Measuring phenotypic reporter loss (e.g., loss of GFP fluorescence) via fluorometry.

Data Analysis & Evaluation

Transforming raw data into meaningful scientific conclusions:

Editing Verification & Efficiency Evaluation Using colony PCR + Sanger sequencing of individual clones as the primary method to verify edits and assess editing efficiency.

Off-Target & Specificity Assessment Assessing predicted off-target loci using targeted PCR followed by Sanger sequencing or targeted deep sequencing.

Phenotype Correlation Analysis Students statistically correlate genomic editing percentage with functional protein activity reduction across experimental replicates.
