Genes from different sources that are related in sequence due to shared evolutionary ancestry are called ________ genes, and groups of such genes are known as ________
Typically ________ of ORFs in a genome cannot clearly be assigned a function. These ORFs are usually assigned and predicted to encode hypothetical proteins
Many of the genes in the chloroplast genome encode proteins involved in ________, whereas mitochondrial genomes primarily encode proteins involved in ________
Gene function is annotated based on homology between the ORFs of a genome and proteins whose function has been proven experimentally. What "-omic" approach could help us determine the function and structure of proteins encoded by uncharacterized
