In order for offspring to have a dominant mutation, they need at least one copy of the allele from either or both parents. So yes, at least one of the parents must have the mutated gene in order for the offspring to have the mutation.
For your second question, I'm not quite sure what you mean so I will restate two possibilities for what I think you mean:
1. The offspring does not have the mutation if none of the parents have the mutated gene: this is correct.
2. If the mutation is recessive and the child has only one copy of the mutated allele, then the child will not show the mutation. If none of the parents had the mutated gene, then it would not be possible for the child to have the mutated gene or show it.

What is Microorganisms?</h3>
Microorganisms, often known as microbes, are minute organisms that can be single cells or colonies of cells.
Ancient texts like the Jain scriptures from India's sixth century BC raised the specter of the potential existence of invisible microscopic life. In the 1670s, Anton van Leeuwenhoek used a microscope to observe microorganisms, which marked the beginning of the scientific study of microbes. Louis Pasteur disproved the hypothesis of spontaneous generation in the 1850s by discovering that bacteria were to blame for food degradation. Robert Koch determined in the 1880s that bacteria were to blame for tuberculosis, cholera, diphtheria, and anthrax.
