The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine
vesna_86 [32]

Answer:

The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine during transcription is adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine.

Explanation:

Transcription of DNA into messenger RNA (mRNA) is a process in which the specific nucleotide sequence is transferred from one molecule to another, through the synthesis of mRNA molecules from a DNA strand.

The complete transcription process is done by nitrogenous base complementarity, where mRNA receives the sequence of complementary bases according to the DNA sequence:

  • <em>Adenine</em><em> is complemented with uracil, since in RNA the thymine is substituted by this uracil. </em>
  • <em>Thymine</em><em> is complemented with adenine. </em>
  • <em>Cytosine</em><em> is complemented with guanine. </em>
  • <em>Guanine</em><em> is complemented with cytosine. </em>

Thus an <u>uracil mRNA sequence, guanine, cytosine, guanine adenine uracil adenine U-G-C-G-A-U-A-A comes from a DNA sequence adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine or A-C-G-C-T-A-T</u>.
