"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 cell. How can such different organisms have this same subset of genes

A Typical Prokaryotic cell

Explanation:

A gene group is a lot of qualities that share significant features. As a rule, gene in a group share a comparable grouping of DNA building squares (nucleotide)These qualities give directions to making products, (for example, proteins) that have a comparative structure or function Prokaryotes are unicellular living beings that need organelles or other interior layer bound  structuresThe nucleoid is  a piece of round ,the double stranded DNA is situated in  territory of the cells.It don't have a nucleus
