Question

Plasmids in the same family are incompatible becauseــــــــــــــــــــــ .
A)they are transferable
B)they produce toxins
C)they carry genes for antibiotic resistance
D)they have similar DNA sequences in the replication genes

Accepted Answer

Plasmids in the same family are incompatible because they have similar DNA sequences in the replication genes. This means that they cannot live together in the same bacterial cell and replicate properly, leading to competition and eventual loss of one or both plasmids.
