Question

Transposons can move

• A. To a specific site on a chromosome
• B. To any site on a chromosome
• C. To nearly any site on a chromosome
• D. All of the above

Answer 1

The correct option is D All of the above

Transposons are sequences of DNA that can move or transpose themselves to new positions within the genome of a single cell. The mechanism of transposition can be either copy and paste or cut and paste. Transposition can create phenotypically significant mutations and alter the cells genome size. Barbara McClintock's discovery of these jumping genes early in her career earned her a Nobel Prize in 1983.
