Final answer:
The three stages of transcription of DNA are initiation, elongation, and termination, resulting in an mRNA molecule. In eukaryotes, the mRNA is further processed before translation. For a template DNA sequence of TTAAACGGCCTA, the transcribed mRNA sequence would be AAUUGCCGGAUU.
Step-by-step explanation:
The process of transcription in DNA involves three main stages: initiation, elongation, and termination. During initiation, the RNA polymerase binds to the promoter region of the DNA, starting the transcription process. During elongation, the RNA polymerase reads the DNA template strand and synthesizes a complementary strand of messenger RNA (mRNA). In termination, transcription concludes when the RNA polymerase reaches a stop signal on the DNA, releasing the mRNA transcript.
The final product of transcription is an mRNA molecule that is a complementary copy of the gene's DNA sequence. After transcription, the fourth step, which occurs in eukaryotic cells, is the processing of the newly formed mRNA, where it undergoes splicing, capping, and polyadenylation before leaving the nucleus for translation into a protein.
Given a template strand with the sequence TTAAACGGCCTA, the corresponding mRNA sequence transcribed would be AAUUGCCGGAUU, following the base pairing rules where adenine (A) pairs with uracil (U) in RNA, and cytosine (C) pairs with guanine (G).
