Final answer:
The three alternative forms of DNA replication are conservative, semi-conservative, and dispersive.
Step-by-step explanation:
The three alternative forms of DNA are conservative, semi-conservative, and dispersive
Conservative replication is a model in which the original DNA molecule remains intact and a completely new molecule is produced. Semi-conservative replication is a model in which each new DNA molecule consists of one original strand and one newly synthesized strand. Dispersive replication is a model in which each new DNA molecule contains a mixture of original and newly synthesized DNA.
These different forms of DNA replication were suggested based on experimental evidence and observations of the process of DNA replication.
