Suppose the following amino acid chain was created based on a student's transcription and translation:
Tyr-Leu-Pro-Met
In the chain, which data show a possible source of error? Explain the error.
HELP PLEASE IM BEING TIMED DJFLKASD
idrcatall:
rip i failed
for anyone else who will need it, the answer is: The position of Met is incorrect
The amino acid sequences of all proteins begin with Met because it is the amino acid that is attached to the anticodon for the AUG start codon.
It looks like the student might have worked in a backward direction for transcription.

for every amino acid chain it begins Met so this makes the amino acid chain ineffective and rendered incorrect so the protein will not function thus the error should be reversed to begin with met and end with Tyr

Hello!
=> For any chain to start it is necessary that it starts with Met.
=> Because this is attached with AUG anticodon.
=> The chain which is not started with Met will be ineffective.
=> So, the defect here is the position of met.
Thanks!

In the amino acid chain, the error lies in the position of the Met/ Methionine.
During protein synthesis by the process of translation, AUG acts as the start codon,i.e. protein synthesis starts from the AUG codon by placing a methionine amino acid at that place.
It is because AUG codes for methionine in prokaryotes and a modified methionine( formylated methionine) in case of prokaryotes.
