Which of these is NOT a use for DNA Fingerprinting?
Identifying the person whose DNA was left at a crime scene
Determining the father of a child
Finding the likelihood of inheriting a genetic disorder
Figuring out which species are more closely related
Why did scientists edit the genes of bacteria to produce insulin?
Because the bacteria were diabetic
Because bacteria have simple DNA that is easier to manipulate, making it easy to produce insulin in a lab
Because bacteria's complex DNA was perfect for insulin production
Because insulin has no use outside of a lab setting
Bacterial DNA is _________ than human DNA
More simple
Less simple
uglier
deadlier
This is the practice of choosing individuals of a species to mate based on their desirable characteristics
Bacterial recombination
Natural selection
Genetic modification
Selective breeding
Which of these is the correct definition of genetic modification/genetic engineering?
Choosing individuals to mate based on desired characteristics
Observing genetic changes in populations over time based on adaptive traits
Extracting stem cells to differentiate into specialized tissues
Altering the DNA of an organism at the molecular level
________ are used to ________ DNA pieces by ________
Restriction enzymes, connect, fission
Restriction enzymes, isolate, "snipping"
Plasmids, connect, fission
Plasmids, isolate, "snipping"
What does transgenic mean?
An organism that can change its genes at will
A stem cell that can differentiate into anything
An organism that has had another species' DNA put in it
A bacteria that reproduces asexually
In preparation for an electrophoresis procedure, enzymes are added to DNA in order to
convert the DNA into gel
cut the DNA into fragments
change the color of the DNA
produce longer sections of DNA
The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel
electrophoresis results is shown below. Which conclusion is valid based on the gel electrophoresis results?
They have the correct child, because her genetic information is identical to that of the father.
They have the wrong child, because her genetic information does not match that of either parent.
They have the correct child, because her genetic information came from both parents.
They have the wrong child, because her genetic information matches only that of the mother.
The results of which laboratory technique are represented in the diagram?
chromatography
manipulation of genes
genetic engineering
gel electrophoresis
Gel electrophoresis is used to separate DNA fragments on the basis of which property?
size
color
functions
chromosomes
