Question 2. Retroviruses are used in gene therapy. The goal of gene therapy is to insert in the patient genome a copy of a functional gene that is defective in the patient. Since Retroviruses integrates their genome into the host genome they are ideal gene therapy delivery systems. What would be a potential risk of this type of treatment? The individual treated could be more susceptible to infection by other retroviruses Insertion of the retroviral genome into the host genome can cause dangerous mutations. There are not recognized risks with this gene therapy approach. Genes from the host can be inserted into the retroviruses and laterally moved to other cells.

QUESTION 48 Identify the best match between the mutation description and term. a. Synonymous mutation: has the potential to cause large changes in transcription and subsequence amino acid sequence due to reading frameshifts b. Nonsense mutation: causes a drastic change in phenotype because the change causes a premature stop in the amino acid sequence c. Indel: a change in the DNA that changes the codon code from one amino acid to another amino acid d. Missense mutation: results in a change in single nucleotide from a purine to another purine or a pyrimidine to another pyrimidine but does not change the amino acid sequence
