Question
Homologous genes can be identified in different organisms by locating a gene in one organism and thenMultiple choice question.mapping its distance from another gene in the same organism.inducing a mutation in the gene.transferring it into another organism that can produce the protein product.comparing it to known genes in databases.
Solution
The correct answer is: comparing it to known genes in databases.
Here's why: Homologous genes are genes in different species that originated by descent from a single gene of the last common ancestor. The species in question can be very closely related or very distantly related. Therefore, to identify homologous genes in different organisms, scientists can compare the gene in one organism to known genes in databases. These databases contain genetic information from many different organisms, allowing for comparison and identification of homologous genes.
