Study Notes
Satellite Repetitive DNA Sequences
- Also referred to as transposons
- Contrary to their name, composed of repetitive sequences that occur in multiple copies
- Not typically gene-rich regions, but rather transcriptionally inactive
- Characterized by tandem repeats, which can be classified based on the number of repeats
- Classified into different types based on the size of the repeat unit
Activation of Amino Acids for Translation
- Involves preparation for protein synthesis
- Requires specific steps to enable amino acid incorporation into polypeptide chains
