Answer:
The transcription product of the sequence GCTAGCGATGAC is CGAUCGCUACUG.
Explanation:
In DNA, the complementary base pairs are adenine (A) with thymine (T) and cytosine (C) with guanine (G) while in RNA, they are adenine (A) with uracil (U) and cytosine (C) with guanine (G). The protein synthesis in a eukaryotic cell consists of two processes, transcription and translation. In the transcription process, the information from a DNA strand (acts as a template) is copied into a single stranded messenger RNA (mRNA) molecule by matching complementary bases to the original DNA strand using an enzyme known as RNA polymerase. This occur in the nucleus. Initiation, elongation, and termination are the three stages of transcription. During initiation, the DNA unwinds and the RNA polymerase enzyme decipher the bases in one of the DNA strands and makes a new mRNA strand with a complementary sequence of bases. In elongation, nucleotides are added to the mRNA strand. During the ending process of transcription called termination, the completed mRNA strand detaches from DNA and exits the nucleus and goes into a ribosome in the cytoplasm. In the cytoplasm, translation occurs where the genetic code in mRNA is read and used in protein synthesis. Since the mRNA sequence is complementary to the DNA template, it's not an exact copy of the DNA segment even though it contains the same information as DNA.
