Final answer:
The complementary RNA sequence to the provided DNA template strand 5'-CAGAGGAATTTTCTG-3' would be 3'-GUCUCCUUAAAAGAC-5', assembled in the opposite orientation during the transcription process by the RNA polymerase enzyme.
Step-by-step explanation:
The student has asked about how to determine the sequence of an RNA molecule that will result from the template strand of a DNA double helix with a given sequence. When the DNA sequence provided is 5′-CAGAGGAATTTTCTG-3′, the complementary RNA sequence will be assembled in the opposite orientation, which means it would be built from the 3' end to the 5' end of the DNA template strand.
To obtain the mRNA sequence, each DNA nucleotide on the template strand is replaced with its RNA complement: cytosine (C) is replaced with guanine (G), guanine (G) with cytosine (C), adenine (A) with uracil (U), and thymine (T) with adenine (A). Therefore, the RNA sequence that complements the given DNA template strand is 3'-GUCUCCUUAAAAGAC-5'.
This process is known as transcription, where the enzyme RNA polymerase reads the DNA template strand and synthesizes a single-stranded RNA molecule that is complementary to the DNA.
