Proteins, among the most complex of all organic compounds, are composed ofamino acids<span> (see Figure 2-4), which contain </span>carbon<span>, hydrogen, </span>oxygen, andnitrogen<span> atoms. Certain </span>amino acids<span> also have </span>sulfur atoms<span>, </span>phosphorus<span>, or other trace elements such as iron or copper.</span>
It occurs at plate boundaries. Hope I helped!
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.
Answer:
I think the correct answer is D.
Answer: A, the white mice are able to reproduce faster (the mouses only differ in color).
