Shared Genes: Why Humans & Prokaryotes Share 1000?
Chapter 1, Problem 10(choose chapter or problem)
A typical prokaryotic cell has about 3,000 genes in its DNA, while a human cell has about 20,500 genes. About 1,000 of these genes are present in both types of cells. Based on your understanding of evolution, explain how such different organisms could have this same subset of genes. What sorts of functions might these shared genes have?

ANSWER:Step 1 of 4
A prokaryotic cell is a simple cell with no nuclear membrane, and the nucleic material lies scattered within a nucleoid. This is a key distinction between eukaryotic and prokaryotic cells as the former has its genetic material properly enclosed within a membrane-bound nucleus.
