Web2 mei 2024 · I think splitting the DNA sequence is more efficient than using str.find, as you need to search for stop codon counting by 3, if using str.find, you would need to judge whether the found stop codon is at a distance of 3. Edit: Currently I don't know whether creating new list of strings would cost more than searching in the original string. safe stocks to invest in uk https://stonecapitalinvestments.com
