What are the two methods of transposition for transposable elements?
Understand the Problem
The question is asking to identify the two methods of transposition for transposable elements from the options provided. It requires knowledge about genetics and transposable elements specifically.
Answer
Copy and paste; Cut and paste
The two methods of transposition for transposable elements are 'copy and paste' (Class I TEs) and 'cut and paste' (Class II TEs).
Answer for screen readers
The two methods of transposition for transposable elements are 'copy and paste' (Class I TEs) and 'cut and paste' (Class II TEs).
More Information
Transposable elements are often referred to as 'jumping genes' due to their ability to move locations within a genome. Class I TEs use an RNA intermediate, while Class II TEs involve a direct DNA transposition mechanism.
Tips
A common mistake is confusing the mechanisms of Class I and Class II TEs. Remember, 'copy and paste' for Class I (which involves RNA) and 'cut and paste' for Class II (which involves DNA).
