<span>Shine-Dalgarno sequence is a sequence that precedes the starting codon in the mRNA. the small sub-unity of ribosome will recognize it with by a specific sequence in the initiation phase of translation.
The best way to restore the translation speed if the Shine Dalgarno sequence is mutated is to make a change in the small sub-unity of the ribosome, specifically in the RNA sequence that recognizes the mRNA Shine Dalgarno sequence, so it can be recognized again. and the translation process will be restored.
</span>Another way to improve a translation speed if to provoke a mutation in the proteins' genes involved in the translation process (like enzymes and translation factors), there will be a chance to increase their effectiveness, especially for enzymes, so the translation speed will be improved.
Answer: Telomerase is the enzyme responsible for maintenance of the length of telomeres by addition of guanine-rich repetitive sequences. Telomerase activity is exhibited in gametes and stem and tumor cells.
