Sample interview questions: Describe your knowledge of transposable elements and their impact on genomes.
Sample answer:
-
Transposable Elements (TEs):
- TEs, also known as mobile genetic elements, are segments of DNA capable of moving within and between genomes.
- TEs make up a significant portion of most eukaryotic genomes, ranging from 2% to more than 50%.
- They can be classified into two main groups:
- Retrotransposons: TEs that move via an RNA intermediate.
- DNA transposons: TEs that move directly from one DNA location to another.
-
Impact of TEs on Genomes:
- Genomic Instability: TEs can contribute to genomic instability by causing mutations, deletions, insertions, and rearrangements.
- Evolution: TEs can promote evolution by providing … Read full answer
