Question

Match the following genetic terms with their appropriate descriptions:

• A. A-IV, B-I, C-III, D-II
• B. A-II, B-III, C-IV, D-I
• C. A-III, B-I, C-IV, D-II
• D. A-I, B-III, C-IV, D-II

Hint:

Remember, matching genetic terms with their definitions requires understanding the basic mechanisms of genetic changes and their biological impacts. Familiarity with these terms aids in comprehending complex genetic disorders and the effects of environmental factors on DNA.

Answer 1

The Correct Option is C

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.
