AUGGCUCUGTGUAGUUGA

#### Explanation:

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). During the process of transcription, each nitrogenous base is connected with it's pair, (Guanine and Cytosine)
(Adenine and Thymine)
However one must remember that RNA contains uracil instead of Thymine. Therefore whenever there is supposed to be a "T" on the MRNA strand, there will be a "U"

The transcribed mRNA would be
3'- AUGGCUCUACAUAGUUGA-5'#

#### Explanation:

Transcription is the process of copying a strand of DNA into a strand of mRNA in the nucleus to prepare for protein synthesis.

The transcription would utilize complimentary base pairing rules for DNA to RNA

A-U Adenine to Uracil
T-A Thymine to Adenine
C-G Cytosine to Guanine
G-C Guanine to Cytosine

Uracil replaces thymine in RNA

For the original DNA strand of
3'- TACCGAGATGTATCAACT -5'

The transcribed mRNA would be
5'- AUGGCUCUACAUAGUUGA-3'

$\textcolor{red}{5 ' - \text{AUGGCUCUACAUAGUUGA} - 3 '}$

#### Explanation:

We start with a $3 '$ and end with a $5 '$, so the transcribed $\text{mRNA}$ would start with a $5 '$ and end with a $3 '$.

So, we get:

$5 ' - 3 '$

Now, we need to convert the nitrogenous bases. Thymine $\left(\text{T}\right)$ only bonds with adenine through two hydrogen bonds, while guanine $\left(\text{G}\right)$ only bonds with cytosine $\left(\text{C}\right)$ with three hydrogen bonds.

And so, we exchange partners. $\text{A}$ turns to $\text{T}$, and $\text{C}$ turns to $\text{G}$. Note that this can also happen vice-versa.

Then, we get:

$5 ' - \text{ATGGCTCTACATAGTTGA} - 3 '$

Since this is the $\text{mRNA}$ strand, any thymines present must be replaced by uracil $\left(\text{U}\right)$.

Our final template becomes:

$\textcolor{red}{5 ' - \text{AUGGCUCUACAUAGUUGA} - 3 '}$
