The correct answer is microbiology.  
<span>
Microbiology is the branch of science that study microorganism. It contains a few sub-disciplines including virology (study viruses), parasitology (study parasites), mycology (study fungi) and bacteriology (study bacteria). Studied microorganism might be unicellular (one cell), multicellular (cell colony), or acellular (without cells).</span>

Cystathioninuria can be caused by two different mutations in the enzyme cystathionase. Cystathioninuria caused by mutation 1 can
polet [3.4K]

Answer:

C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.

Explanation:

A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.

A species of fly has two alleles for the length of their legs. The allele for long
stira [4]

Answer:

According to Hardy Weinberg law (p+q)2=1 where p is fequency of one allele and q is the frequency of another allele.

According the question

 q represent the short legs and 33 of 100 organism have short legs.

   As a result the frequency of q with respect to the 100 organism is 33/100

                                                                                                                  =0.33

Therefore q=0.33

 we all know that

            (p+q)2=1

             ∴  p+q= 1

             ∴  p=1-q

               p= 1-0.33

                   p=0.67

The frequency of p is 0.67
