Answer:
Non-zero digits are always significant. Any zeros between two non-zero digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant.
Explanation:
Answer:
D. the Y chromosome
Explanation:
Men have an X and a Y chromosome while women have two X chromosomes. Since the unusual chromosome was spread to nearly 16 million men, it was most likely a Y-linked trait as only men inherit a Y chromosome. If it was an X-linked trait, both men and women would be able to get it since both inherit X chromosomes.
Hope that helps.
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.
