What is the purpose of gel in DNA profiling?
To amplify DNA fragments
To serve as a molecular sieve for sorting DNA fragments by size
To stain DNA fragments
To replicate DNA fragments
What is the process called where DNA fragments are separated by size using a gel?
PCR
Electrophoresis
STR analysis
DNA replication
What does STR stand for in DNA analysis?
Short Tandem Repeats
Single Tandem Repeats
Simple Tandem Repeats

Why is STR analysis useful in DNA profiling?
It amplifies DNA for analysis
It stains DNA for visualization
It separates DNA fragments by size
It replicates DNA fragments
What is PCR used for in DNA analysis?
To separate DNA fragments by size
To amplify DNA fragments
To stain DNA fragments
To identify DNA sequences
Match the following:
PCR
amplification of a DNA or protein sample for analysis
Gel electrophoresis
used to separate fragments of DNA or protein
DNA fingerprint
pattern of DNA fragments used to identify an individual
Bacterial transformation
taking up foreign DNA by a bacterium
Match the following
cannot be answered by gathering measurable data. They may be opinion-based or about abstract concepts.
Nontestable Question
can be answered by making observations, but the variables cannot be manipulated. Data is gathered based on naturally occurring situations.
Observational testable questions:
can be answered through controlled experiments where one variable is changed (independent variable) to see its effect on another variable (dependent variable).
Experimental testable questions
Organize these options into the right categories
Why do people think birds are beautiful?
(This is subjective and cannot be answered through data
How do trees feel about losing their leaves in the fall?
How do trees feel about losing their le
How do the behaviors of birds change during the different seasons?
How do the behaviors of birds
How does the temperature of the water affect the swimming speed of fish?
How does the temperatur
How does the amount of light affect the growth of tomato plants?
How does the number of bird species vary between different habitats (forest vs. desert)?
This is what’s being tested. It’s the factor that you, as the scientist, are changing in the experiment. Be sure to include details about how it is manipulated.
Independent Variable
Dependent Variable
Constant
Control Group
This is what changes as a result in the experiment. It is usually the data that is collected. Be sure to include details about what you are measuring and how you are measuring it.
Independent Variable
Dependent Variable
Constant
Control Group
All the things that are the same for all groups in the experiment. A good experiment has LOTS, and should be specifically related to the experiment (for example: “5 weeks” instead of “amount of time” and “measure height of plant in cm” instead of “same ruler”)
Independent Variable
Dependent Variable
Constants
Control Group
This is the part of the experiment that gets no treatment or normal treatment - it is used as a comparison, to get a baseline so you can tell if the treatment causes a difference.

Suzie Q wants to know the effect of different colors of light on the growth of plants. She believes that plants can survive best in white light. She buys 5 ferns of the same species, which are all approximately the same age and height. She places one in white light, one in blue light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a day for 2 weeks. After the two weeks, Suzie observes the plants and makes measurements.
