Answer #1

Question 1 :

Answer : Serine

Explanation : Serine is the only polar, neutral amino acid among the given four. Therefore, it must be more acidic as compared to remaining non-polar amino acids.

Question 2 :

Answer : Disulfide bridges

Explanation : These are the strongest forces holding tertiary structure of proteins because they are covalent bonds.

Question 3 :

Answer : Valine

Explanation : Valine is a hydrophobic( water repellent) amino acid. Therefore, it is less likely to be present on the surface of a protein in water.

Question 4 :

To form a dipeptide bond between leucine and glycine, the - OH from -COOH of leucine can be removed and -H from -NH3 of glycine can be removed together as H2O and the remaining structure can be joined forming peptide bond.

    Sickle-cell Anemia Study Sickle-cell anemia or Sickle-cell disease, is a hereditary disorder. characterized by aryabnormality in the oxygen-carrying hemoglobin molecule in erythrocytes. Sickle-cell conditions have an autosomal recessive pattern of inheritance from parents. The sickle cell defect is a mutation of a single nucleotide of the hemoglobin B gene, which results in glutamic acid being substituted by a different amino acid at position 6. Hemoglobin with this mutation is referred to as Hbs, as opposed to the normal hemoglobin HbA....
