"tertiary structure of a protein is maintained by (list the interactions)"
erik [133]

<span>Protein tertiary structures are known to be a three dimensional structure of a protein with a single polypeptide chain (backbone) and one or more protein secondary structures known as protein domains.</span>

Tertiary Structure Interactions

1) Hydrophobic Interactions: they are non- covalent bonds and very important in the formation of tertiary structure. 

2) Ionic Bonds: the interaction of both positive and negative amino acids forms a bond that helps to stabilize the protein molecules. 

3) Hydrogen Bonds: this bond exit between the amino acid with hydrophilic side chain found on the surface of the molecules and water molecules in a solution.

4) Disulfide Bridges: it is a strong covalent bond commonly found between cysteine residues in close proximity space.

What would be the outcome of crossing two strains of wingless flies that belong to the same complementation group?
STALIN [3.7K]

Answer:

Wingless offspring

Explanation:

Complementation is the terminology used for finding difference in the mutation of same or different gene.  

Two groups with same complementation have failed to complement each other.  

Thus, two wingless flies will have the same genotype i.e “ww”

When two wingless flies are crossed following offspring are produced  

ww * ww  

ww, ww, ww, ww

All the offspring are wingless too
