Hm, this could be more than one option, but gaining electrons makes a negative charge, so
If atoms of a halogen nonmetal (Group 17) gains one electron, the atoms the have "a negative one charge".
Answer:
The sequence of an amino acid P is:
Glu-Gly-Lys-Ala-Ser-Phe-Lys-Gln-Val-Ile
Explanation:
Fragments obtained on hydrolysis of decapeptide P by the action of an enzyme named trypsin:
- Glu-Gly-Lys,
- Gln-Val-Ile
- Ala-Ser-Phe-Lys
Fragments obtained on hydrolysis of decapeptide P by the action of an enzyme named chymotrypsin:
- Lys-Gln-Val-Ile,
- Glu-Gly-Lys-Ala-Ser-Phe
In order to determine the sequence of protein P , we will arrange fragments in such a way so that common fragments or the common parts of fragments should come under each other.
On arranging these fragments :
Glu-Gly-Lys-Ala-Ser-Phe
Glu-Gly-Lys
Ala-Ser-Phe-Lys
Lys-Gln-Val-Ile
Gln-Val-Ile
The sequence of an amino acid P is:
Glu-Gly-Lys-Ala-Ser-Phe-Lys-Gln-Val-Ile
