Answer:
In order to clone the sequence of the gene for one of the human crystallins found in the eye, there is a need for the application of polymerase chain reaction. In the process, the particular sequence of gene is denatured and then replicated various times to generate various clones of the gene sequence.
By producing various copies of the gene sequence for the human crystallin, that is, desirable, a scientist can examine various distinct characteristics of the protein as there is always more to examine with.

Answer:
The answer is C
Explanation:
Proteins that were sinthesized in the endoplasmic reticulum are able to leave this organelle inside vesicles that are formed through evagination of the reticulum membrane. These vesicles can merge with the golgi membrane, spreading its contents inside the golgi apparatus. This process can be repeated through all of Golgi's cisternaes, and when the last cisternae is reached, these vesicles can be directed towards the plasma membrane. Once the vesicles and the plasma membrane are merged, all the molecules that were contained inside the vesicle are exported from the cell into the extracellular space.
Dominance involves one allele masking another at the same locus whereas epistasis involves one locus masking a different locus.
Explanation:
Epistasis is a type of gene interaction in which one gene masks or modifies the expression of another gene at a distinct locus.
Dominance refers to the gene interaction in which one allele of a given gene masks the expression of another alllele of same gene.
The comparison of dominance and epistasis give the following information:
- Dominance involves allelic suppression while epistasis involves non-allelic suppression.
- Dominance involves a single pair of alleles while epistasis involves two pairs of allele.
- In dominance, the expression of recessive allele is suppressed while in epistasis, either recessive or dominant non allele is suppressed.
- The effect of dominance is due to the dominant allele while epistasis may be due to dominant or recessive allele.
