Many human genes are known to have homologs in the mouse genome. One approach to investigating human hereditary disease is to produce mutations of the mouse homologs of human genes by methods that can precisely target specific nucleotides for mutation. Numerous studies of mutations of the mouse homologs of human genes have yielded valuable information about how gene mutations influence the human disease process. In general terms, describe how and why creating mutations of the mouse homologs can give information about human hereditary disease processes.

Key Concepts

Homologous Genes

Homologous genes are genes in different species that share a common ancestry and often retain similar functions. In the context of genetics, mouse genes that are homologous to human genes can provide insights into gene function and disease mechanisms. By studying these homologs, researchers can infer how mutations in human genes may lead to hereditary diseases.

Gene Targeting Techniques

Gene targeting techniques, such as CRISPR-Cas9, allow scientists to make precise alterations to specific nucleotides in a gene. This precision enables the creation of mutations in mouse homologs of human genes, which can mimic human genetic disorders. By observing the effects of these mutations in mice, researchers can better understand the biological processes underlying human diseases.

Model Organisms in Genetics

Model organisms, like mice, are extensively used in genetic research due to their genetic, biological, and behavioral similarities to humans. They serve as a practical platform for studying the effects of genetic mutations in a controlled environment. Insights gained from these studies can help elucidate the pathways and mechanisms involved in human hereditary diseases, facilitating the development of potential therapies.
