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

1-fluoro-2,4-dinitrobenzene) followed by hydrolysis gave N-(2,4-dinitrophenyl) alanine. Partial hydrolysis of the nonapeptide gave the following fragments: gly-ala-phe ala-asp-gly-ala phe-ser-ala ser-ala-phe-asp. Which one of the following is the nonapeptide's pripary structure? A) ala-asp-gly-ala-asp-ala-phe-sor-phe B) ala-asp-gly-ala-phe-ser-ala-phe-b C) ala-phe-asp-gly-ala-asp-ser-phe-ala D) gly-ala-phe-ser-ala-phe-asp-asp-ala

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"

Lake Mojave is an ancient lake that has dried up and no longer exists in the Mojave desert in California. Which environmental co
Goshia [24]

The correct answers are:

- Decrease in rainfall in the Mojave desert;

The decrease in rainfall can be devastating to a lake's waters and biodiversity. The decrease in rain usually causes bigger loss of water through evaporation than water coming in the lake, so over time it will dry out, or just small pieces of it will remain.

- Decrease in runoff that flows into Mojave Lake;

If the amount of water that comes into the lake decreases, it can be fatal to it, and in a very short period of time, since the lake will be losing more water than it gets in.

- Increase in blocked streams that flow into Mojave Lake;

Naturally, streams can be blocked and redirected, so if this happens, we have the same situation from before, where the water income is smaller than the water loss of the lake.
