Expert Solution
Step 1

Codon can be defined as the trinucleotide sequence of DNA or RNA which corresponds to a specific amino acid or stop signal at the time of protein synthesis.A genetic code helps in describing the relationship between the sequence of bases(A,C,G and T) and protein sequence it encodes.

Step 2

1)RNA is composed of four nitrogenous bases :Adenine, cytosine, uracil and Guanine.Uracil is similar to Thymine in structure,but Thymine is found in DNA.

Rules of base pairing are:

  • Purine Adenine with pyrimidine Thymine in DNA and in RNA Adenine pairs up with uracil
  • Pyrimidine cytosine pairs with purine guanine

So according to this rule 

Answer is 

1)A DNA codon of ATT is complementary to this RNA codon:UAA

Step 3

2)Stop codons signals the termination of polypeptide chain at the time of translation.They are also called nonsense codons or termination codon because they do not code for an amino acid.

There are three stop codons:UAG,UAA,UGA

So answer is 

This codon terminates a coding region:UAA
