For the DNA sequence 5'-GTGTAGGCCTTGAG-3', what will be the sequence of the newly synthesized mRNA?

For the DNA sequence 5'-GTGTAGGCCTTGAG-3', what will be the sequence of the newly synthesized mRNA?

• A. 5ʹ-GUGUAGGCCUUGAG-3ʹ
• B. 5ʹ-GAGUUCCGGAUGUG-3ʹ
• C. 5ʹ-CUCAAGGCCUACAC-3ʹ
• D. 5ʹ-CACAUCCGGAACUC-3ʹ

Answer: (C)

To determine the sequence of the newly synthesized mRNA from the given DNA sequence, it’s important to remember that mRNA is created during the process of transcription, where the DNA template strand is used to produce a complementary RNA strand. The given DNA sequence, 5'-GTGTAGGCCTTGAG-3', represents the coding (non-template) strand. During transcription, the RNA polymerase will read the template strand of the DNA in the 3' to 5' direction and synthesize the mRNA in the 5' to 3' direction. To accurately produce the mRNA sequence, we must first convert the DNA sequence into the complementary RNA sequence, replacing thymine (T) with uracil (U). Hence, the transcription process will lead to the following transformations for each base: - G (guanine) pairs with C (cytosine) in RNA. - T (thymine) pairs with A (adenine) in RNA. - A (adenine) pairs with U (uracil) in RNA. - C (cytosine) remains C in RNA. From the DNA sequence: GTGTAGGCCTTGAG, the corresponding mRNA synthesized will be: -

• G (guanine) pairs with C (cytosine) in RNA.

• T (thymine) pairs with A (adenine) in RNA.

• A (adenine) pairs with U (uracil) in RNA.

• C (cytosine) remains C in RNA.

From the DNA sequence: GTGTAGGCCTTGAG, the corresponding mRNA synthesized will be:
