The model shows the creation of which of the following?
Recombinant DNA
Hybrid
Polyploid
DNA mutation
The final product of the process shown above is an example of…
restriction enzymes because the plasmid DNA and cell gene are combined from two different sources.
recombinant DNA because the plasmid DNA and cell gene are combined from two different sources.
a DNA fingerprint because the combination of DNA is now different from both the plant and the bacteria.
a clone because the combination of DNA is identical to both the bacterium and the cell.
What is the purpose of restriction enzymes in the process shown above?
Cut the DNA of the cell and the bacterial plasmid to create sticky ends that can be joined together.
Cut open the cell wall of the bacterium to access the DNA.
Seal the gaps between the sticky ends of the bacterial plasmid and the cell gene.
Make the recombinant DNA resistance to antibiotics.
Which sheep will the cloned lamb be identical to?
Sheep C because it was the foster mother.
None of the sheep (A, B, nor C).
Sheep A because it donated the DNA.
Sheep B because it donated the egg.
What are the benefits of using the biotechnology technique shown above?
The DNA of four different individuals can be compared.
The physical characteristics of four different individuals can be compared.
The DNA of one individual can be analyzed for point mutations.
The physical characteristics of an individual can be analyzed for genetic disorders.
According to the image below, which male horse is the father of the daughter horse?
Male 1
Male 2
Male 3
Male 4
Recall that Cystic Fibrosis is a genetic disorder in which an individual cannot produce the CFTR protein and as a result, experiences frequent lung infections, persistent coughing, and shortness of breath. Which of the following questions would BEST guide a scientist researching potential gene therapy for Cystic Fibrosis?
Will injecting CFTR protein directly into a patient’s lung cure Cystic Fibrosis?
Will producing a vaccine to administer to a CF patient cure Cystic Fibrosis?
Will replicating the dysfunctional copy of the patient’s CFTR protein cure Cystic Fibrosis?
Will inserting a normally functioning copy of the CFTR protein gene in a patient’s lung cells cure Cystic Fibrosis?

A rooster with pink feathers is mated with a hen of the same phenotype. They produce 15 chicks with pink feathers, 6 chicks with white feathers, and 8 chicks with red feathers. What is the simplest explanation for this inheritance pattern?
The trait is recessive, which produces red or white when the pink allele is not present.
The trait is codominant, which produces pink when red and white are crossed.
The trait is dominant, which produces pink even when the red and white alleles are present.
The trait is incompletely dominant, which produces pink when red and white are crossed.
The allele which is designated with a lowercase letter is the
Recessive Allele
Phenotype
Genotype
Dominant Allele
