Answer:
This question is unclear and incomplete. The comprehensive and complete question is:
A DNA sequence is shown below. TAGGAGCAT. What is produced when the sequence is transcribed?
A. a chain of three amino acids
B. a set of three tRNA molecules C. a section of DNA with the base sequence ATCCTCGTA
D. a section of mRNA with the base sequence AUCCUCGUA
The answer is D. a section of mRNA with the base sequence AUCCUCGUA
Step-by-step explanation:
Transcription is the first stage of gene expression which involves the synthesis of a mRNA molecule using a DNA template. The process of transcription is carried out by an enzyme called RNA polymerase, which adds complementary nucleotide bases to the mRNA sequence.
According to the complementary base pairing rule, RNA polymerase uses A-T, G-C pairing. However, Uracil base replaces Thymine base in the mRNA strand.
Hence, a DNA sequence: TAGGAGCAT is transcribed into a section of mRNA with the base sequence AUCCUCGUA
