This is the set-up of our experiment. There are four plates shown: LB only (a type of nutrient agar), LB/AMP (LB agar with ampicillin included), and LB/AMP/Arabinose (LB agar with ampicillin and arabinose). All plates were spread with E. coli following the transformation procedure described in the video. Some of the E. coli samples were mixed with PGLO plasmid DNA (+DNA samples) and some E. coli samples were not (-DNA).
Molecular Techniques
Molecular techniques are methods employed in molecular biology, genetics, biochemistry, and biophysics to manipulate and analyze nucleic acids (deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)), protein, and lipids. Techniques in molecular biology are employed to investigate the molecular basis for biological activity. These techniques are used to analyze cellular properties, structures, and chemical reactions, with a focus on how certain molecules regulate cellular reactions and growth.
DNA Fingerprinting and Gel Electrophoresis
The genetic makeup of living organisms is shown by a technique known as DNA fingerprinting. The difference is the satellite region of DNA is shown by this process. Alex Jeffreys has invented the process of DNA fingerprinting in 1985. Any biological samples such as blood, hair, saliva, semen can be used for DNA fingerprinting. DNA fingerprinting is also known as DNA profiling or molecular fingerprinting.
Molecular Markers
A known DNA sequence or gene sequence is present on a chromosome, and it is associated with a specific trait or character. It is mainly used as a genetic marker of the molecular marker. The first genetic map was done in a fruit fly, using genes as the first marker. In two categories, molecular markers are classified, classical marker and a DNA marker. A molecular marker is also known as a genetic marker.
DNA Sequencing
The most important feature of DNA (deoxyribonucleic acid) molecules are nucleotide sequences and the identification of genes and their activities. This the reason why scientists have been working to determine the sequences of pieces of DNA covered under the genomic field. The primary objective of the Human Genome Project was to determine the nucleotide sequence of the entire human nuclear genome. DNA sequencing selectively eliminates the introns leading to only exome sequencing that allows proteins coding.
![**Experiment Setup and Analysis**
**4. Experimental Setup:**
This experiment involves four agar plates with different conditions:
- **Plate A (LB only):** Contains a standard nutrient agar (LB).
- **Plate B (LB/AMP):** Contains LB agar with ampicillin.
- **Plate C (LB/AMP):** Contains LB agar with ampicillin.
- **Plate D (LB/AMP/ARA):** Contains LB agar with ampicillin and arabinose.
All plates were inoculated with *E. coli* following a transformation protocol. Some *E. coli* samples were mixed with pGLO plasmid DNA (+DNA samples) and others were not (-DNA samples).
**Diagram:**
- **Plate A (-DNA):** Shows only LB. No DNA was added.
- **Plate B (-DNA):** Contains LB with ampicillin. No DNA was added.
- **Plate C (+DNA):** Contains LB with ampicillin. DNA was added.
- **Plate D (+DNA):** Contains LB with ampicillin and arabinose. DNA was added.
**5. Results Analysis:**
Complete the chart below to predict the experiment's results based on specific questions linked to transformation:
| **Question** | **Plate A** | **Plate B** | **Plate C** | **Plate D** |
|---------------------------------------------------------------|-------------|-------------|-------------|-------------|
| 1. Did the *E. coli* added to the plate have the pGLO plasmid? | No | No | Yes | Yes |
| 2. Was the *E. coli* ampicillin resistant? | No | No | Determine | Determine |
| 3. Based on B, should the *E. coli* have grown on the plate? | Yes | No | Yes | Yes |
| 4. If *E. coli* should grow, should it also glow? | No | No | No | Yes |
| 5. Plates A & B are included as controls. If no growth on Plate A or growth on Plate B, what do these indicate? | Control Growth | No Growth | Transformation Success | Arabinose Induces GFP Expression |
This setup and analysis guide is used to observe bacterial transformation and antibiotic resistance. In particular, it assesses how the presence of the pGLO plasm](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff702feb7-178f-43b5-89e7-1452a507e5d6%2F90501a8b-0f5c-4886-a602-bd299dd5619e%2F77hz51_processed.jpeg&w=3840&q=75)
