What two main conditions are necessary for an extinct animal to be cloned?

To clone an extinct animal, two main conditions are necessary: the availability of well-preserved genetic material, typically DNA, from the extinct species, and a closely related living species to serve as a surrogate or host for the cloning process. The quality and integrity of the DNA are crucial, as degraded samples may not provide sufficient genetic information for successful cloning. Additionally, advanced cloning techniques, such as somatic cell nuclear transfer, must be employed to facilitate the process.
