Complete hydrolysis of a nonapeptide gave 3 ala, 2 phe, 2 asp, gly, and ser. Reaction of the nonapeptide with Sanger's reagent (
Wewaii [24]

Answer:

Alanine is obtained as the first amino acid, taking into account that the reaction with the Sanger reagent hydrolyzes N- (2,4-dinitrophenyl) alanine. thus with the fragments of the partial hydrolysis they are organized to create a polypetidic chain

ala-asp-gly-ala

gly-ala-phe

phe-be-wing

be-wing-phe-asp

We obtain that the correct sequence of the peptide is "ala-asp-gly-ala-phe-ser-ala-phe-asp"

Leni [432]

Answer:

Translation is the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. The process starts where the mRNAs (messenger RNA) copies the DNA and sends this message to the ribosome. In the ribosome for each triplet of nucleotide an amino acid is bond to the growing chain of amino acid that will eventually form a protein.

You can look up for the translation for the genetic on the internet. Which tells you which triplet codifies for an specific amino acid.

If the code reads. CGC GCG CGC GCG etc.

The result would be an a peptide/protein containing alternating arginines and alanines, because CGC codifies for Arginine and GCG codifies for alanine.
