A) replacing the genomes of an individual with a brand-new set of genomes with the goal of treating a genetic defect
B) replacing a defective gene in an individual with a normal gene with the goal of treating a genetic disorder
C) transferring a mutated gene into an individual with the goal of treating a genetic defect
D) transferring a normal or a modified gene into an individual with the goal of treating a genetic defect
E) replacing a defective enzyme in an individual with a normal enzyme with the goal of treating a genetic disorder

Accepted Answer

Gene therapy involves transferring a normal or modified gene into an individual to treat a genetic defect.

Question 7

Crops have been genetically modified to resist the herbicide ____.
A) glyphosate
B) DDT
C) triazine
D) 2,4-D
E) atrazine

Accepted Answer

Glyphosate is a common herbicide that crops have been genetically modified to resist, allowing farmers to use it to control weeds without harming the crops.

Question 8

The idea of deliberately improving the genetic qualities of the human race is referred to as ____.​
A) ​genomics
B) ​genetic cloning
C) ​gene therapy
D) ​eugenics
E) ​euthanasia

Accepted Answer

Eugenics is the practice or advocacy of improving the genetic quality of the human species or a human population, especially by such means as discouraging reproduction by persons having genetic defects or presumed to have inheritable undesirable traits (negative eugenics) or encouraging reproduction by persons presumed to have inheritable desirable traits (positive eugenics).

Question 9

Matching
Match the following organisms to the description with which they best correspond.
-transgenic animals that produce proteins used to treat human conditions, such as cystic fibrosis, heart attacks, blood clotting disorders, and nerve gas exposure
A)A. tumefaciens
B)rice
C)E. coli
D)goats
E)mice

The answer of Matching
Match the following organisms to the description...

Question 10

β-Carotene is converted to vitamin ____ in the cells of the small intestine.
A) B12
B) A
C) E
D) C
E) D

Accepted Answer

β-Carotene is a precursor to vitamin A, meaning that it is converted into vitamin A in the body, specifically within the cells of the small intestine.

Question 11

If a virus-injected gene interrupts a growth control gene, ____ could result.​
A) diabetes​
B) ​cancer
C) ​hemophilia A
D) sickle-cell anemia​
E) ​heart attack

Accepted Answer

Cancer could result because the interruption of a growth control gene by a virus-injected gene can lead to uncontrolled cell growth, which is a hallmark of cancer.

Question 12

Matching
Match the following organisms to the description with which they best correspond.
-genes can be introduced into plant cells using this bacteria
A)A. tumefaciens
B)rice
C)E. coli
D)goats
E)mice

Accepted Answer

The answer of Matching
Match the following organisms to the description...

Question 13

In gene therapy, what is transferred into an individual's chromosomes?​
A) a new genome​
B) ​an unmutated gene
C) ​a mutated gene
D) ​bacterial plasmids
E) ​DNA libraries

Accepted Answer

In gene therapy, an unmutated (healthy or functional) gene is transferred into an individual's chromosomes to replace or repair a mutated gene that causes disease. This process aims to correct or alleviate the genetic disorder by providing a correct copy of the gene.

Question 14

Match the following terms to the definition with which they best correspond.
-an organism's complete set of genetic material
A)single-nucleotide polymorphism

Question 17

Currently, the only possible cure for genetic disorders is ____.​
A) genetically modified drugs​
B) ​transplantation
C) ​whole genome replacement
D) ​gene therapy

Which human body system is affected in individuals with SCIDs?​
A) ​digestive
B) ​immune
C) ​reproductive
D) ​nervous
