Final answer:

The correct RNA sequence produced during transcription from the DNA base sequence TAA CTA TGA CGT CG is AUU GAU ACU GCA GC. This RNA then carries the genetic code from the DNA to the ribosomes for protein synthesis. Each codon on the mRNA corresponds to a specific amino acid in the protein that is created.

Step-by-step explanation:

The student's question revolves around the transcription process in which the DNA sequence is used to synthesize an RNA molecule. The DNA base sequence provided is TAA CTA TGA CGT CG. During transcription, each DNA base is transcribed into a complementary RNA base with adenine (A) pairing with uracil (U), and cytosine (C) pairing with guanine (G), guanine (G) with cytosine (C), and thymine (T) with adenine (A).

The correct RNA sequence produced during the transcription process from the given DNA sequence would be AUU GAU ACU GCA GC, which represents option a) in the provided choices. This is because the adenine (A) in DNA is replaced by uracil (U) in RNA, and the remaining bases pair as usual.

The final product of transcription is messenger RNA (mRNA), which carries the genetic information from DNA to the ribosomes, where proteins are synthesized. Each group of three bases on the mRNA, known as a codon, corresponds to one amino acid. In other words, the DNA's genetic code is translated into a sequence of amino acids that will form a protein.
