Translocation is defined as:

Translocation is defined as:

• A. When one piece of chromosome is transferred to another chromosome
• B. When a gene is duplicated
• C. When mRNA is translated
• D. When a base is deleted

Answer: (A)

Translocation is a chromosomal rearrangement where a piece of one chromosome moves to a different chromosome. The statement that a piece of a chromosome is transferred to another chromosome captures this idea directly, and translocations can be reciprocal (segments exchanged between two chromosomes) or non-reciprocal (a segment moves to another chromosome). The other options describe different genetic changes: duplication is when a segment is copied, mRNA translation is a step in protein synthesis, and a base deletion is a point mutation altering a nucleotide.
