Prokaryote

...s where DNA is transferred between cells, such as transformation and transduction . While prokaryotes are nearly always unicelluar, some are capable of forming groups of cells called colonies . Unlike many eukaryotic multicellular organisms, each member of the colony is undifferentiated and capable of free-li...

...s as the " genotype-phenotype map ". T 2 is the transformation due to natural selection, T 3 are epigenetic relations that predict genotypes based on the selected phenotypes and finally T 4 the rules of Mendelian genetics. In practice, there are two bodies of evolutionary theory that exist in parallel, tr...

Bacteria which took up one or more copies of the plasmid then express (make protein) the gene that confers antibiotic resistance. This is typically a protein which can break down any antibiotics that...
