Question

In a mixed copolymer experiment, messages were created with either 4/5C : 1/5A or 4/5A : 1/5C. These messages yielded proteins with the following amino acid compositions.

Table showing amino acid yields from mixed copolymer experiments in genetics.

Using these data, predict the most specific coding composition for each amino acid.

Accepted Answer

Hi everyone. Let's take a look at this practice problem together. Suppose that only A and C are used for synthesizing an M R N A in a ratio of one A 25 C determine the frequency of C C C of hearing in the message. So in the sequence, there's one A for every five C, that means that there are six total outcomes possible. So for every position of a nucleotide in an M RNA sequence, so if this was an an M RNA sequence and each dashed for a nucleotide, the probability of one of those nucleotides being added meaning or A is one out of six. The probability Of one of those nucleotides being a side is seen or C is five out of six. So to determine the frequency of C C C occurring in the M R N A, it's now a probability of multiple events. And in order to determine the probability of multiple events, you multiply the independent probabilities together. So that means that we have three separate independent events, one event for each nucleotide position possibly being occupied by A C. So our calculation would look like five out of six, since that's the probability of C multiplied by another five out of six, multiplied by five out of six. When you multiply this together you get five times five times five equals 100 and 25 divided by six times six times six equals 216. And when you do that calculation, this equals 57.87. Therefore, the correct answer is option D 58% is the frequency of CCC appearing in the message. Alright, everyone. I hope you found this helpful and I'll see you soon for the next practice problem.
