Question at position 34 Genetically engineered mosquitoes are being used to fight mosquito-borne illnesses. These mosquitoes have been outfitted with a gene that makes them resistant to pathogens like malaria. To ensure that the resistance gene is transmitted through the entire mosquito population, genetic engineers have attached the it to a gene drive, a self-genetic element that biases what cell division process?transposon jumpinginterphasemeiosismitosisgametogenesisClear my selection

Question

BlackTom AI · Accepted Answer

Let's begin by restating what the question is asking: Identify which cell division process a gene drive biases to ensure a resistance gene is passed through the mosquito population.
Option 1: transposon jumping. This refers to transposable elements moving within the genome, not to biased inheritance during reproduction. It does not describe how a gene drive ensures propagation through generations.
Option 2: interphase. Interphase is the cell cycle stage between divisions where the genome is replicated and cells grow. It is not the division process that governs inheritance to offspring, so it does not explain how a gene drive biases transmission.
Option 3: meiosis. Meiosis is the specialized cell division that produces gametes (sperm and eggs) with half the chromosome number. A gene drive is designed to bias inheritance during this process so the allele is transmitted to more than 50% of the offspring, allowing the resistance gene to spread through the population. This is the correct mechanism.
Option 4: mitosis. Mitosis generates somatic (non-reproductive) cells with the same chromosome number as the parent. It does not directly influence inheritance patterns in offspring, so it does not account for gene-drive-driven spread.
Option 5: gametogenesis. Gametogenesis is the overall process of forming gametes, which includes meiosis as a key part. While related, the specific biasing event occurs during meiosis itself, not during the entire broader process of gamete formation. Therefore, this choice is less precise.
In summary, the gene drive operates by biasing inheritance during meiosis, the cell division stage that creates gametes and allows the allele to be propagated to the next generation. The other options describe related concepts or stages but do not capture the mechanism by which a gene drive ensures biased transmission through offspring.
