Of dna technology is important when the results are to be used as evidence in a court of law.

Reliability

Explanation:

The reliability of DNA technology is essential when the result is to be used in court as it is used to support other evidence. If the procedure for the collection of the DNA evidence is flawed, its reliability could be called to question, and it may not be admissible in court. This may raise questions whether those who carried out the test are adequately qualified, whether DNA samples were contaminated, and so on.  

anticipatory breach of contract

as the name suggests, an anticipatory breach is a breach of contract before the time of performance. so, if a promisor denies to perform his promise and signifies his unwillingness before the time for performance, then it is an anticipatory breach of contract.

and

actual breach of contract

while an anticipatory breach is before the time of performance, an actual breach of contract is on the scheduled time of performance of the contract. an actual breach of contract can be committed either.
