GENETIC ENGINEERING & ETHICS
This small circular DNA molecule is commonly used in genetic engineering.
Plasmid
This organelle controls the activities of the cell and contains DNA.
Nucleus
The prefix “bio-” means this.
Life
A student touches bacterial cultures without gloves. This is what type of issue?
Safety issue
A scientist changes the amount of sunlight plants receive to measure growth. What is the independent variable?
Amount of sunlight
Bacteria are commonly used in biotechnology because they reproduce this way.
Rapidly/Quickly
Prokaryotic cells do NOT have this membrane-bound structure.
A transgenic organism contains this type of DNA.
DNA from another organism/species
A scientist accidentally contaminates a bacterial plate. This lab practice likely failed.
aseptic technique
A scientist measures bacterial growth after changing temperature. What is the dependent variable?
Bacterial Growth
This plasmid feature allows scientists to identify bacteria carrying recombinant DNA.
Selectable Marker
This circular structure holds bacterial genetic information
Plasmid
Bioremediation uses organisms to do this.
clean up environmental pollution
A scientist wants to study only one species of bacteria. They should use this technique.
Streak plating
In an experiment testing antibiotics, keeping the same amount of bacteria in every sample is this type of variable.
Controlled variable
A promoter does this in genetic engineering.
start/control gene expression
This structure helps some bacteria move.
Flagellum
This term describes scientific knowledge based on observations and evidence.
Empirical
A bacterial culture is not disposed of properly. Name one possible risk.
contamination/spread of pathogen
A scientist concludes bacteria are harmful because colonies are yellow. Is this an observation or inference?
Inference
Releasing genetically modified organisms without proper testing is this type of concern.
Ethical concern
Gram staining differentiates bacteria off of what structure
Cell wall
Observations are different from inferences because observations are this.
Directly seen/measured
A scientist uses a patient's DNA without having them sign a consent form. What type of issue is this?
Legal issue
A scientist tests whether fertilizer affects plant growth but changes both fertilizer amount and light exposure. What is wrong with the experiment?
More than one independent variable was changed
