(a) Study the table given below and identify (i), (ii), (iii) and (iv)
`{:("Amino acid","Phe","Val"),("DNA Code in Gene","AAA","CAC"),("Codon in mRNA",(i),(ii)),("Anticodon in tRNA",(iii),(iv)):}`
(b) A polypeptide consists of 14 different amino acids.
(i) How many base pairs must be there in the processed mRNA that codes for this polypeptide?
(ii) How many different types of tRNA are needed for the synthesis of this polypeptide ?

Explanation

To solve the question, we will analyze the provided table and identify the missing elements step by step.

### Step-by-Step Solution:

1. **Identify the Codons in mRNA (i) and (ii)**:
- The amino acids provided are Phenylalanine (Phe) and Valine (Val).
- The DNA code for Phe is AAA. The corresponding codon in mRNA is derived from the DNA template. The DNA triplet AAA transcribes to mRNA as UUU (since A pairs with U in RNA).
- The DNA code for Valine is CAC. The corresponding codon in mRNA for Valine is GUG (since C pairs with G and A pairs with U).
