<span>The transcription of mRNA begins in the nucleus. The DNA is uncoiled and the nucleic acids with nitrogen bases adenine, thymine, guanine, and cytosine combine to form an incomplete mRNA. The current RNA contains exons (the coding region) and introns (non-informational regions). The introns are cut out and remaining exons are spliced together. Now the mRNA goes through polyadenylation. This is the process where the 3' end of the mRNA is attached with multiple adenine nucleotides. On the 5' end of the mRNA, a 5' cap is attached. This is the complete and functional mRNA. At this point, the mRNA exits the nucleus to join with the ribosome, ending the transcription and starting the process of translation. </span>

The sequence of the mRNA that would result from transcribing a DNA template strand with the bases TACGCTAAT would be AUGCGAUUA.

<h3>What is transcription?</h3>

Transcription is the first stage of gene expression in which mRNA sequence is produced from a DNA template.

During transcription, the following applies to the DNA molecule being transcribed:

Adenine base (A) is transcribed into Uracil (U)
Guanine base (G) is transcribed into Cytosine (C) and vice versa.
Thymine base (T) is transcribed into Adenine (A)

Therefore, the sequence of the mRNA that would result from transcribing a DNA template strand with the bases TACGCTAAT would be AUGCGAUUA.

What is the sugar found in DNA that makes up the sugar-phosphate backbone of the double helix?

Georgia [21]

Answer:

deoxyribose

Explanation:

A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

I hope that this helped you ;)
