Introduction:
A mutation refers to the permanent alteration of the DNA (deoxyribonucleic acid) sequence in an organism. The mutations can occur due to the insertion, deletion, or change in the base-pair of the DNA sequence.
Answer to Problem 1TYK
Correct answer:
The change in the base pair during replication process is referred to as a mutation.
Explanation of Solution
Explanation/Justification for the correct answer:
Option (a) is given as a mutation. An alteration in the base-pair of the sequence during the
Explanation for the incorrect answers:
Option (b) is given as mutations that fall in the protein-coding part of the gene. These mutations are known as missense mutations, which also come under mutations only. So, it is an incorrect option.
Option (c) is given as mutation in the transcribed part of the genome. Even, if the mutation does not fall in the protein-coding part or in the transcribed part of the genome, it would still be called as a mutation. So, it is an incorrect option.
Option (d) is given as single base-pair change is not considered as mutation. A change in a single base-pair has the potential to change the whole DNA sequence. Hence, a single base-pair change is also considered as a mutation. So, it is an incorrect option.
Hence, the options (b), (c), and (d) are incorrect.
A mutation is an alteration in the genome. The change in the base-pair of the DNA sequence is always considered as a mutation, no matter where it is present.

Goal 1: To alleviate the client's overall level, frequency, and intensity of anxiety and PTSD symptoms so that daily functioning remains unimpaired. Objective 1: The client will learn and regularly use at least two anxieties management techniques to reduce anxiety symptoms to less than three episodes per week. Intervention 1: The therapist will provide psychoeducation about anxiety and PTSD, including their symptoms and triggers. The therapist will also teach and assist the client in adopting relaxation techniques, such as deep breathing exercises and progressive muscle relaxation, to better manage anxiety and lessen PTSD symptoms.arrow_forward
