Abiologist finds out that the fruit fly, drosophila, makes a protein in its eyes that has a very similar structure when compared to a human protein that was just discovered in the newly sequenced human genome. the biologist concludes that the human protein might be important for the proper development and working of the human eye. which unifying theme in biology is illustrated in this example?

The correct answer will be- comparative genomics.

Explanation:

Comparative genomics is a fundamental tool in which the DNA sequence and the whole gene set of a genome of two different organisms are compared.

The comparison is done to measure the difference and common genomic features by comparison of gene order, gene loss, horizontal gene transfer, duplication and gene regulation.

Since in the given question, the genome of Drosophila and the humans were compared to identify the conserved functional elements throughout genome therefore, comparative genomics is the correct answer.

answer: dna

because all cells have genes
