Cell Biology Basics
This lipid forms the main structural component of cell membranes.
What are phospholipids?
This molecule carries genetic information in living organisms.
What is DNA?
These blood cells are responsible for transporting oxygen.
What are red blood cells?
This structure enables bacteria to move.
What is a flagellum?
These organisms are capable of producing their own food.
What are autotrophs?
This organelle is known as the cell’s “shipping and receiving” center.
What is the Golgi apparatus?
This nitrogenous base replaces thymine in RNA.
What is uracil?
This ion is primarily responsible for depolarization in a neuron.
What is sodium (Na⁺)?
These helminths are commonly known as roundworms.
What are nematodes?
This ecological relationship benefits one organism while harming another.
What is parasitism?
This process refers to programmed cell death during development.
What is apoptosis?
This type of cell division produces two genetically identical daughter cells.
What is mitosis?
This phase of the action potential occurs when potassium ions exit the neuron.
What is repolarization?
This microbial growth phase shows the highest rate of cell division.
What is the log (exponential) phase?
This evolutionary mechanism causes random changes in allele frequency.
What is genetic drift?
This model explains the fluid and dynamic nature of the cell membrane.
What is the Fluid Mosaic Model?
These “jumping genes” move through an RNA intermediate.
What are retrotransposons?
This functional unit of the kidney filters blood and forms urine.
What is the nephron?
These helminths are also called flukes.
What are trematodes?
This term refers to the total number of disease cases at a given time.
What is prevalence?
This protein wraps around DNA to form nucleosomes in eukaryotic cells.
What is histone?
These enzymes attach the correct amino acid to its corresponding tRNA.
What are aminoacyl-tRNA synthetases?
This pancreatic hormone lowers blood glucose levels by promoting glucose uptake.
What is insulin?
This snail-borne helminth causes schistosomiasis.
What is Schistosoma?
This link in the chain of infection was targeted when Typhoid Mary was isolated.
What is the reservoir?
