What is recombinant DNA
DNA from 2 different organisms combined
DNA from 2 different ribosomes
DNA that is separated out from a vector
Which of the following could be used as a vector for a human gene?
Bacterial Plasmid with recombinant DNA or a virus
Bacteria colonies
A mitochondria
mRNA in proteins
In which ways can genetic engineering can improve crops
Make them pest or drought resistant
Make them more nutritious
Make them larger
All answers are correct
"transgenic" refers to an animal that:
Has DNA from another organism spliced into its genome
Has undergone selective breeding
Has unique genes for its species
Humans with genetic diseases can have a gene inserted into their body using a virus vector. This is called:
Gene therapy
Cloning
DNA fingerprinting
When DNA is manipulated and moved from one source to another it is known as
genetic engineering/transformation
electrophoresis/ DNA finger finger printing
gene therapy
polymerase chain reaction
A clone is
recombinant DNA
a transgenic organsim
plasmid
genetically identical to the doner cell
Gene therapy
Cloning (scnt)
DNA Fingerprinting
Gene Splicing
all of these are reasons for using Genetically modified crops
What is the purpose of cloning?
an off spring created from DNA from a somatic cell
offspring from egg cells
selective breeding of animals with desirable traits
Foreign genes are inserted into a cell to make recombinant DNA during
Cell Transformation
Cloning
gel electrophoresis
human genome project
Which technology below would probably be the most important to a person who had diabetes and had to take insulin every day?
using recombinant DNA to produce human hormones in bacteria
testing parents for genetic disorders before they have children
engineering fruits and vegetables that resist insects and other pests
developing ways to identify criminals through DNA fingerprinting
How do scientists cut DNA into smaller strands?
restriction enzymes
scissors
ligase
agarose
If a scientist has a small amount of DNA what must they do in order to make identical copies of it for genetic analysis?
transformation
use the DNA as a template for PCR - making copies
sort it by size in gel electrophoresis
fuse it into a new cell to make a clone
In order to insert a human gene into plasmid, both must
code for the same gene product.
be cut by the same restriction enzyme.
originate from the same type of cell.
have identical sequences.
The process of putting recombinant DNA into an organism's cell is called....
Gene transformation
The source of genetic variability comes from
mutations
clones
hybridization
selective breeding
How do scientists make many copies of segments of DNA?
PCR
DNA finger printing
restriction enzyme
transformation
How are transgenic plants advantageous?
improving diets
using more insecticides
making clones
increasing diversity
In mammal clones which cells are used to make a clone.
egg cells
body and egg cell with no nucleus
body cells
body and sperm cells
What is the sex chromosomes of a female? of a Male
xx and y
xy and xx
xx and xy
What is a genetic marker
traits like antibiotic resistance that can be used to verify transformation
traits in a pedigree
DNA fingerprinting
Choose all of the natural clones
two regenerated star fish
Two genetically identical bacteria in a colony
a transgenic pig
a human
Analyzing DNA using Gel Electrophoresis we separate DNA fragments which
allows scientists to compare DNA of different organisms
allows the cutting of DNA
creates a clone
allows for selective breeding of similar organisms
somatic cells are
body cells in adults
sex cells
embryonic cells
Utilizing existing variation within a population to choose which individuals reproduce allows a researcher to
embryonic cell transfer
increase desired traits in an offspring
clone the organism
make transgenic cells
Bacterial plasmids are used to
insert foreign DNA
clone an animal
cut DNA
DNA finger printing /gel electrophoresis is important because
people do not have identical DNA (except identical twins)
people have repeating sections of DNA
Only important genes are different in humans
all organisms have a similar genenome
Gene therapy is used to
provide cures for viral diseases
sort DNA by size
cure genetic diseases
transfer genes to other organisms
What is the ultimate source of genetic variability?
Mutations
only embryonic cells
tissue cells
Meiosis
Analyzing DNA by gel electrophoresis allows researchers to
identify both dominant and recessive genes
identify similarities and differences in the DNA of different individuals.
select desired traits
make clones
Which statement best describes genetic engineering?
making plants with multiple genes
Growing tissues
altering the genetic material of the organism to have a foreign gene
the process of grafting or transplanting organs or tissues between members of different species.
gene therapy
Genetic manipulation
fertilization making a zygote
inserting a gene into a diseased cell so that the correct protein is created.
used only to create genetically modified organisms
