Final answer:
The correct term for a change in an organism's DNA is called a mutation, which can occur from various factors. Unlike adaptations, which are long-term traits, mutations can have varying effects on an organism. The correct answer to the question is option C: mutation.
Explanation:
Understanding DNA Changes
The term for a change in an organism's DNA is called a mutation. Mutations can occur due to errors in DNA replication, exposure to radiation, chemicals, or viral infections. There are several types of mutations:
- Point mutation: A change in a single nucleotide, which can affect protein function.
- Insertion mutation: Addition of one or more nucleotides, potentially altering the reading frame of genes.
- Deletion mutation: Removal of one or more nucleotides, which can also shift the reading frame.
Unlike adaptations, which are traits developed over generations that help organisms survive in their environments, mutations are often random changes that can have beneficial, harmful, or neutral effects on the organism.
In contrast, translation refers to the process where ribosomes synthesize proteins based on the mRNA template, not to changes in DNA. Thus, the correct answer is C: mutation.
