Students have asked these similar questions
A. What is the pathogen that is attacking bananas today?b. Why is this especially problematic in Africa?
C. Why do we expect to lose the war with this pathogen?d. What is random mutagenesis?
Which letter is correct
A. Genetic engineering is preferred because a desired gene to crops may not exist in their species, so conventional agriculture could not be applied.
B. Conventional agriculture is preferred because they're natural, and don't have interference in their genome, so they're healthier.
C. Genetic engineering is preferred because through it, we can create new species of plants resistant to pests.
D. Conventional agriculture is preferred because they produce more crop compared to genetic modifications.
When using gene therapy to treat an hereditary disease, the idea is to:
A. Introduce the correct gene into the patient's DNA
B. Inject the patient with a specific protein to cure the disease.
C. Blood transfusions from healthy individuals.
D. ntroduce mRNA molecules with the correct genetic information to the patient.
E. Introduce a virus to the patient that will specifically destroy mutated cells.

- In general, all mutations can be considered harmful, because most genetic systems are already optimized to work correctly and efficiently. A. True b. False; mutations are considered harmful only if they have a direct effect on the ability of cells to synthesize DNA c. False; some mutations are harmful, and some are considered beneficialarrow_forward1a) Why is it possible for you to study the eye colour gene by extracting cheek cells? a. Because the nucleus of every cell in the human body contains the same genetic information. b. Because the cheek cells are located near the cells of the eye and so they are able to exchange DNA. c. Because all genes in the human body are expressed at all times so it is easy to study them. d. All of the above are possible explanations. 1b) What is the purpose of heating the sample to 75°C following addition of the 0.2M NaOH solution? a. To denature the histone proteins that are keeping the DNA tightly coiled. b. To ensure that all the DNA is removed from the swab in preparation for PCR. c. To breakdown the cheek cell membrane to release the DNA from the cell. d. It breaks down the circular DNA down into linear fragments so that they will be easier to visualize.iarrow_forwardExplain the difference between gene modification and gene addition.Are the following examples of gene modification or gene addition?A.

- Gene therapy is performed by ____. a. replacing a defective enzyme in an individual with a normal enzyme with the goal of treating a genetic disorder b. transferring a normal or a modified gene into an individual with the goal of treating a genetic defect c. transferring a mutated gene into an individual with the goal of treating a genetic defect d. replacing a defective gene in an individual with a normal gene with the goal of treating a genetic disorder e. replacing the genomes of an individual with a brand new set of genomes with the goal of treating a genetic defectarrow_forwardWhich of the following BEST states genome editing in plants? A. transform large DNA constructs by suppression and activation B. insert a functional cis-regulatory element in the natural genes transgene vector C. assemble and synthesize large DNA molecules in a single transgene vector D. deletion, mutation, or integration of the gene of interest depending on the target traitarrow_forwardA gene contains the sequence CGCATACGGTAC that results in the amino acid sequence arg-ile-arg- tyr. A mutation in this gene has a G inserted after the second C in the strand. How will this mutation affect the phenotype? A:This will affect the phenotype because although most of the protein will be identical, the first amino acid will be different. B:This will not affect the phenotype because only the second amino acid is different from the original protein. C:This will not affect the phenotype because the protein will be identical to the original protein. D:This will affect the phenotvpe because all of the amino acids after the first one will be different from he original protein.arrow_forward
