Match the following genetic terms with their appropriate descriptions:
Correctly associating each term with its definition.
A (Change in a single base): is typically referred to as a Point Mutation, which is a type of mutation where a single nucleotide base is changed, inserted, or deleted from the sequence of DNA. This matches with III.
B (Deletion of base pairs of DNA): often results in a Frame Shift Mutation, which occurs when the DNA sequence is altered in such a way that it shifts the way the sequence is read. Hence, B matches with I.
C (Cancer cells): are often characterized by Chromosomal Aberrations, which are changes to the overall structure of the chromosomes, leading to significant genetic disruption, matching C with IV.
D (UV radiation): is a well-known Mutagen, which can cause changes or mutations in the DNA. Therefore, D matches with II.
