Examine the polypeptide in its major ionization state at pH 1. -How many amino acids are present in this peptide? **Can you please circle them and label? I'm having a hard time identifying where they are. The chart I have seems off from what I see here. -Also, at what pH in an isoelectric focusing gel should you look for this purified peptide? Explain. Thanks for the help! OH HAN OH IZ (CH2), CH 9 HEN 6

Question 8 2.5 pts If a protein (polypeptide) is composed of 210 amino acids, how many mRNA codons would be required? Question 9 2.5 pts If a protein (polypeptide) is composed of 210 amino acids, how many mRNA ribonucleotides would be required?
Explain this question please! Name (4 ofer to the Table of Amino Acids at the beginning of the exam to help solve this problem. Polypeptide I is a 12-mer and has the following amino acid composition: Ala, Arg, 2 His, Leu, 2 Lys, 2 Phe, Ser, Thr, Trp Edman degradation of I shows that its N-terminal amino acid is His. Chymotrypsin cleavage of I yields peptide fragments A-D.Trypsin cleavage of I gives peptide fragments E-G. Shown below is the amino...
