Which of the Following are Genes of Common Ancestry in Two

Question

Which of the following are genes of common ancestry in two genomes that share the same function?
A) homologs
B) open reading frames
C) proteomes
D) orthologs
E) lysogenic

Accepted Answer

Orthologs are genes in different organisms that evolved from a common ancestral gene by speciation, and they typically have the same function in both organisms. This means that two genomes that share the same function will likely have orthologous genes. Homologs refer to genes that are similar due to common ancestry, but the term is more broad and can encompass both orthologs and paralogs (genes that evolved from a duplication event). Open reading frames and proteomes refer to different aspects of gene expression, and lysogenic refers to a type of viral life cycle and is not related to genes of common ancestry.
