The trp repressor blocks transcription of the trp operon when the repressor binds to tryptophan. The trp repressor or the tryptophan repressor is a transcription factor that is involved in controlling amino acid metabolism. In the trp operon, tryptophan binds to the repressor protein thus effectively blocking gene transcription.
Answer:
First Image
Explanation:
Amino acid order is NCC (Nitrogen, alpha carbon with R group attached, and carboxy group).
If we start with methionine, then we write its nitrogen, then alpha carbon and then carboxy and then alanine's nitronge, alpha, carboxy, and end with glycine nitrogen, alpha and carboxy.
I have labelled the "R" groups to show amino acids. First is methionine, then alanine and then glycine.
