Hi everyone. Let's take a look at this practice problem together. What is the minimum number of nucleotides needed to code a protein with 52 Amino assets? So a 52 amino acid protein is going to have 52 code ins because one coat on equals one amino acid. However, don't forget about the stop code on recall that every M R N a strand that is translated has a stop code on. So a 52 amino acid protein Will have 52 code ons Plus one Stop Code on. So that's going to give us 53 code on total. And then you would multiply this by three because recall that there are three nucleotides in each coat on. So that's going to give us 100 and nucleotides. Or as it's written in our answers 100 and 59 base pairs since each nucleotide is bonded to be a base pair. So our answer is going to be c 159 base pairs. Alright everyone. I hope you found this helpful and I'll see you for the next practice problem.
