Within its genome, an organism must encode all of the genes necessary for maintaining life and for multiplying. As organisms increase in complexity, the size of their genomes and the total number of genes tend to increase. While there are exceptions to this trend, organism complexity can still be useful for the estimation of genome size.
1. Arrange the organisms below by genome size.
a. Oryza sativa (rice)
b. Mus musculus (mouse)
c. Drosophila melanogaster (fruit fly)
d. Homo sapiens (human)
