MCQ
Mobile genetic elements in maize were discovered by ___________:
- AD. Baltimore
- BH. G. Khorana
- CN. E. Borlaug
- DB. McClintock
Explanation:
A transposable element is a DNA sequence that can change its position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size.
They are also termed as mobile genetic elements. Barbara McClintock discovered the first transposable elements in maize (Zea mays) at the Cold Spring Harbor Laboratory in New York and earned a noble prize in 1983.
