This is the practice of cutting DNA and separating it by the size of the pieces
Cloning
Gel Electrophoresis
Genetic Engineering
DNA Fingerprinting
What is the name of the international effort to sequence a human's DNA sequence?

The Nuremberg Trials
The Human Genome Project
Which kitten is most likely the offspring of this cat?
1
2
3
4
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
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
What is the process in which an unspecialized stem cell turns into a specialized body cell?
DNA Replication
Differentiation
Respiration
Genetic Modification
________ 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 reproductive cloning, the egg cell of one organism is used by removing the __________ nucleus and then combining the __________ nucleus from a cell from a second individual. Once the cell starts to divide, it is placed in a surrogate mother.
DNA, RNA
RNA, DNA
haploid, diploid
diploid, haploid
What cell organelle carries its own DNA passed down from the mother and is used to trace genealogy?
ribosome
golgi apparatus
mitochondria
vesicles
The process used to make copies of DNA when not much is available and is often used in forensics is called
gel electrophoresis
cloning
PCR
transgenics
The polymerase chain reaction is important because it allows us to
Make many copies of a targeted segment of DNA
Insert eukaryotic genes into prokaryotic plasmids
Incorporate genes into viruses
Make DNA from RNA
A desired DNA segment is inserted into small circular DNA from prokaryotes called a __________ and then is inserted into a bacterial host and the resulting combination is called ____________.
Virus, a eukaryote
Plasmid, a eukaryote
Plasmid, recombinant DNA
Virion, recombinant DNA
This seals the sticky ends of restriction fragments to make recombinant DNA
restriction enzymes
gene cloning
DNA ligase
reverse transcriptase
Genetically engineered plants
are more difficult to engineer than animals
include a transgenic rice plant that could help prevent vitamin A deficiency
are being rapidly developed, but traditional plant breeding programs are still the only method to develop new plants
are banned throughout the world
