Question

Determine the mRNA sequence for the following DNA sequence. 5'-GCCATTTCCCGTTA-3' Group of answer choices 5'-TAACGGCAAATGGC-3' 5'-CGGUAAAGGGCAAU-3' 5'-UAACGGCAAAUGGC-3' 5'-UAACGGGAAAUGGC-3' 5'-CGGTAAAGGGCAAT-3'

Answer 1

The correct mRNA sequence for the given DNA sequence 5'-GCCATTTCCCGTTA-3' is 5'-CGGAAAGGGAAUGGC-3'.

Step-by-step explanation:

1.Transcription Process: Transcription involves the synthesis of mRNA from a DNA template strand.

2.Complementary Base Pairing: In mRNA synthesis, RNA polymerase pairs complementary RNA nucleotides with the DNA template strand.

3.Transcribing DNA to mRNA: When transcribing the given DNA sequence 5'-GCCATTTCCCGTTA-3':

• The mRNA sequence is synthesized by replacing thymine (T) with uracil (U) and maintaining the complementary bases.

• The mRNA sequence derived from the given DNA sequence is 5'-CGGAAAGGGAAUGGC-3'.

Answer 2

The mRNA sequence for the DNA sequence 5'-GCCATTTCCCGTTA-3' is 5'-CGGUAAAGGGCAAU-3'. It is created by pairing the complementary RNA bases to the given DNA strand and reversing them to get the 5'-3' orientation.

Step-by-step explanation:

Transcribing DNA to mRNA

To determine the mRNA sequence for the given DNA sequence 5'-GCCATTTCCCGTTA-3', you need to understand the base pairing rules between DNA and RNA. Adenine (A) pairs with Uracil (U) in RNA, and Guanine (G) pairs with Cytosine (C). Therefore, the complementary RNA strand would be 3'-CGGUAAAGGGCAAU-5', which means the 5'-3' mRNA sequence would be 5'-CGGUAAAGGGCAAU-3'. It's important to remember that Thymine (T) in DNA is replaced by Uracil (U) in RNA.

None of the answer choices perfectly match the mRNA that would be transcribed from the DNA strand. The correct mRNA sequence transcribed will be the reverse of the given 3'-5' complementary strand.
