Is called crossing.
Both have bacteria-like polysaccharide cel walls.
Both can reproduce on their own outside of the cell.
Both contain DNA molecules.
Both contain endoplasmic reticulum and Golgi bodies .
Both contain ribosomes that are identical to ribosomes of the eukaryotic cytoplasm.
They are a source of variation for evolution.
They drive evolution by creating mutation pressures.
They are irreversible.
They occur in germ cells but not in somatic cells.
They are most often beneficial to the organisms in which they occur.
A gene can code for a specific protein.
A gene can exist in alternate forms called introns.
A gene undergoes crossing-over during DNA replication.
A gene that is very similar in sequence in a human and in a bacterium is probably a recent mutation.
A gene that is expresses in every offspring of every generation is recessive.
Genes are compose of protein molecules
DNA and proteins are actually the same molecules located in different parts of the cells.
Bacteria injects their DNA into the cytoplasm of bacteriophages.
DNA is the molecule that stores genetic information in the cells.
