### Given the Following DNA MoleculeThis diagram represents a segment of a DNA molecule, which is composed of two complementary strands forming a double helix. Each strand consists of nucleotides, represented by the letters A (adenine), T (thymine), C (cytosine), and G (guanine). #### DNA Strand Details:- **Top Strand (3' to 5')**: 3' - T A C G G T A A A A A C T - 5' - **Bottom Strand (5' to 3')**: 5' - A T G C C A T T T T T G A - 3'Each nucleotide on one strand pairs with its complementary nucleotide on the opposite strand:- A (adenine) pairs with T (thymine)- T (thymine) pairs with A (adenine)- C (cytosine) pairs with G (guanine)- G (guanine) pairs with C (cytosine) The vertical lines between the bases represent hydrogen bonds that hold the two strands together, forming the structure of DNA. The numbers indicate the directionality of each strand, from 3' (three prime) to 5' (five prime) for the top strand, and from 5' to 3' for the bottom strand. This directionality is essential for processes like DNA replication and transcription. a. Write the sequence of the mRNA synthesized from the upper strand.b. Indicate the 5’ and 3’ ends of the message.c. Groups of three letters on the mRNA molecule are called ______________.d. What is the special significance of the first group of three letters in the message?e. What is the special significance of the last group of three letters in the message?

Answer : a. Sequence of mRNA synthesized from the upper stand - 5' AUGCCAUUUUGA 3' b. 5' and 3' ends of the message indicate following: AUG- Methionine and UGA- Tryptophan. AUG is the initiator codon and UGA is the stop codon. AUG- Methionine CCA- Proline UUU- Phenylalanine UGA- Tryptophan c. Groups of three letters on the mRNA molecules are called Codon. A codon can be defined as a triplet sequence of nitrogenous bases in mRNA copied from DNA molecule which codes for a particular amino acid, whereas the genetic code is the sequence of nitrogenous bases in mRNA molecule, which encloses the information for linking of amino acids during the synthesis of protein molecules. d. The special significance of the first group of three letters in the message indicate initiation codon. It marks the beginning of the message for a polypeptide chain. The initiation codon is AUG in majority of cases and it codes for amino acid methionine. e. The special significance of the last group of three letters in the message indicate stop codon. It indicates the termination of polypeptide chain. There are three termination or stop codons: UAA(ochre) UGA(opal) UAG(amber).
