(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

### Step-by-Step Solution

#### Part (a)
1. **Identify the Codons in mRNA:**
- The DNA code for Phenylalanine (Phe) is AAA. When transcribed to mRNA, the corresponding codon will be UUU (since adenine (A) in DNA pairs with uracil (U) in mRNA).
- The DNA code for Valine (Val) is CAC. When transcribed to mRNA, the corresponding codon will be GUG (since cytosine (C) in DNA pairs with guanine (G) in mRNA).

Therefore, we can fill in the table:
