Question

Genes knockouts are organisms that have bad specific genes deactivated. when fully grown, these organisms deploy phenotypes that are different from those organism containing the functioning form of the gene. what does this allow scientists to study

a) Understand the purpose of the genes
b) Study the effects of deactivated genes on phenotypes
c) Examine the functioning form of the gene
d) Investigate the growth patterns of knockout organisms

Answer 1

Gene knockouts are used to study and understand the function of specific genes by comparing the phenotype of knockout organisms to those with the gene active.

Step-by-step explanation:

Gene knockouts allow scientists to study the effects of deactivated genes on phenotypes. This reverse genetics technique helps to understand the purpose of the genes by observing the differences in fully grown organisms with specific genes turned off compared to their normal counterparts. By deactivating genes, scientists can determine their function, as phenotypic differences provide clues about what roles these genes play in an organism's development and functioning. For instance, if knocking out a gene results in a loss of wing development in an insect, it suggests that the targeted gene was involved in wing formation or maintenance.
