Observe the segment of mRNA given below and answers the questions given below:

Explain and illustrate the steps involved to make fully processed hn RNA.

Gene encoding RNA polymerase I and RNA polymerase III have been affected by mutation. Explain its impact on the synthesis of polypeptide giving reasons.

In a particular cattle, the coat colour red and white are controlled by single pair of alleles. A calf that receives allele for red coat from mother and allele for white coat from father shows equal number of red and white hairs on its coat.

Is this an example of Co-dominance or incomplete dominance. Give a reason for your answer.

With the help of a genetic cross upto $\displaystyle \mathrm{F}_{2}$ generation, explain what will be the consequent phenotype of calf when

Red is dominant over white,

Red is incompletely dominant.
