Answer: IT CAUSES PATHOGENS TO STICK TOGETHER
Explanation:
The four nitrogen bases contribute to the variation between humans because the order of nucleotides determines phenotypic features associated with genetic inheritance.
- In DNA, there are four types of nucleotides, each containing one different nitrogen base.
- The four nitrogen bases in DNA nucleotides are Adenine, Guanine, Cytosine, and Thymine.
- The linear order of these nucleotides in genes largely determines the phenotypic features associated with genetic inheritance.
In conclusion, the four nitrogen bases contribute to the variation between humans because the order of nucleotides determines phenotypic features associated with genetic inheritance.

Answer:
a. Always independently stable. Domain
b. Retains native structure even when separated from the rest of the protein. Domain
c. β Barrel. Motif
d. Calcium-binding segments of calmodulin. Motif
e. An advantageous folding pattern composed of two or more secondary structure elements. Domain
f. Sometimes independently stable. Motif
Explanation:
a. Protein domains are evolutionary conserved and stable 3D structures formed by a series of amino acids joined by peptide bonds.
b. Domains are stable because they conserve their tridimensional structure in physiological conditions even if they are separated of the rest of the protein.
c. The ß-barrel motif is a type of motif localized in single-stranded DNA viruses.
d. Calmodulin is a protein that contains calcium-binding motifs that enable to sense intracellular calcium levels.
e. Domain folding patterns are critical transitional states that allow the proteins their interaction with specific ligands in different physiological conditions.
f. Motifs are sometimes independently stable, but due to their short length (3-15 amino acids), protein motifs are generally unstable in different conditions.

Ans.
Tuberculosis (TB) is a bacterial infection that affects mainly respiratory tract and can be transmitted from one to another person through contaminated air. The causative agent of tuberculosis, <em>Mycobacterium tuberculosis</em> has developed resistance against many antibiotics, such as rifampin and isoniazid, which is known as tuberculosis drug resistance.
If a person infected with TB shows drug resistance against some TB drugs, 'doctors should give other TB drugs to that person, even if these drugs show less effect than common drugs'. This is because these drugs can prevent or kill the bacterium more effectively than the common drugs for which, bacterium is resistance.
