Study Notes
Molecular Biology and Genetics
- Restriction enzymes are commonly known as "molecular scissors" due to their ability to cut DNA at specific sequences.
- The ampR gene provides antibiotic resistance, specifically to ampicillin, allowing bacteria containing this gene to survive in environments with this antibiotic.
Plant Biology
- Taichung is a variety of rice, known for its high yield and adaptability in various environmental conditions.
Soil Science
- Nitrogen fixation in soil is predominantly facilitated by certain bacteria, often found in symbiotic relationships with legumes, converting atmospheric nitrogen into a usable form for plants.
Genetics and Gene Regulation
- The Lac operon represents a set of genes involved in lactose metabolism in bacteria, demonstrating gene regulation through the presence or absence of lactose.
Reproductive Biology
- The anterior portion of sperm is converted by a cap-like structure known as the acrosome, which plays a crucial role in penetrating the egg during fertilization.
Human Genetics
- Sickle cell anemia is related to a genetic mutation that affects hemoglobin, leading to misshaped red blood cells and causing various health complications.
Aquaculture
- Pisciculture refers to the culture and breeding of fish, typically practiced to enhance fish populations for food supply or ornamental purposes.
