Question 125 MCQ · 3.0 marks

Suppose you fly to an alien world and are surprised to find that life there follows the same central dogma. The difference is that the alien life has 2 distinct nucleotides that make up DNA sequences and a whopping 600 distinct amino acids that make up protein sequences. What is the minimum length of each codon in this alien species?
