By changing a gene's instructions for making a protein, a variant(mutated protiens) can cause a protein to malfunction or to not be produced at all. When a variant alters a protein that plays a critical role in the body, it can disrupt normal development or cause a health condition.
The series of changes that occurs after a disturbance in an existing ecosystem is called:.

What is the process of genome editing?
Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism's DNA.
The list of the process of genome editing:
1. The target DNA sequence.
2. Sequence with correct gene sequence.
3. The ability to remove the mutated gene sequence.
These technologies allow genetic material to be added, removed, or altered at particular locations in the genome.

How can a medical transcriptionist make sure that the information he or she found on the Internet is valid and accurate? Explain.
Answer:
What is Medical Transcription?
Medical transcription is when a medical report is typed from a dictated audio file recorded by a physician, a nurse, or some other healthcare provider.
Doctors, nurse practitioners, surgeons, and other healthcare providers have important, stressful jobs. They’re on their feet all day, doing everything they can to help the patients in their care. There’s a lot that can get in their way, however, and many frequently express frustration in getting so bogged down with paperwork that it limits their time with their patients.
The number one task that can suck up too much time from healthcare providers is transcribing their own notes. These notes can include everything from clinical summaries to surgery notes. Taking an audio recording and turning it into a written document that’s needed for their own records, insurance claims, and patient’s medical charts can take some providers a few hours per day.
