Answer:
This signifies that the protein primarily comprises multiple polypeptide chains connected together with the help of disulfide bonds. The enzymes may be found in the form of dimers, trimers, or tetramers. Various examples of dimers, trimers, and tetramer proteins are known, of them, NEMOs dimers are considered to be held by disulfide bonds.  
Thus, it can be hypothesized that the enzyme under examination is a multimer held in combination by disulfide bonds, with each comprising catalytic sites. On breaking of disulfide bonds, the enzyme dissociates into its many single units.  
This illustrates the reduction in catalytic activity. Each active site in a single unit will work, however, at a gradual rate. This also shows detection of multiple globular proteins after disulfide reduction.  
 
        
             
        
        
        
Answer: The options are not included.
But the sites are;
Interaction with ribosomes.
Interaction with aminoacyl tRNA 
synthase.
Attachment of the specific Amino acid.
Interaction with codon.
Explanation:
Transfer RNA is a type of RNA that help to translate messenger RNA sequence into protein. Each tRNA have two major areas; the anticodon and region for attaching specific Amino acids.
tRNAs function at specific sites in the ribosomes during mRNA deciding.
The four specific recognition sites of trna that must be inherent in it's tertiary structures in order for it to carry out it's role are;.
Interaction with ribosomes.
Interaction with aminoacyl tRNA synthase.
Attachment of specific Amino acid.
Interaction with codon.
 
        
             
        
        
        
Answer:
Genotype: Bb (heterozygous) 
Phenotype: brown fur
Explanation:
Since allele B is dominant to allele b, as long as genotype has allele B in it, its effect of phenotype will be expressed instead, regardless of whether allele b is present. 
As mouse genotype is stated as Bb, on the chromosome from its parents, allele B comes from one parent while allele b is inherited from the other parent. 
Phenotype is the expressed trait. In this case, as genotype has allele B, the phenotype will be brown fur as its effect is expressed. 
 
        
             
        
        
        
Answer:
Scientists have been concerned that human activities could cause more plants and animals to become extinct than any point in the past. Along with human-made changes in climate (see above), some of these extinctions could be caused by overhunting, overfishing, invasive species, or habitat loss
 
        
             
        
        
        
Taxonomy is the branch of Science, in which
we study the Classification of Organisms. On discovering an unknown organism,
begin classification by looking for anatomical features that appear to have the
same function as those found on other species.
In order to correctly classify an organism,
scientists use many modern tools.
1.Morphology describes the physical
characteristics of an organism. Typically, this is enough information to place
the organism within a domain and kingdom.
2.DNA and biochemical analysis allow
scientists to test less visible, but distinguishing, characteristics.
3.Comparing embryology allows scientists to
group organisms that share common fetal development.
<span>4.Evolutionary
phylogeny describes the evolutionary relationships between organisms.</span>These
relationships are deduced based on shared traits that may have been passed from
ancestor to new species. Traits
may include physical traits (ex. presence of jaws), or may be genetic traits
(shared genes).
