Answer:

The mRNA strand that would be produced from  this DNA template strand: TACCGAT is AUGGCUA (option C).

Explanation:

In transcription, from a strand —template strand— of the DNA molecule, an mRNA molecule is obtained, a process in which the enzyme RNA polymerase is involved.

The synthesis of mRNA occurs by attending to the complemetarity of nitrogenous bases, so that

If DNA strand has:                Complement in mRNA it is:

  • Adenine                          Uracil (no thymine in RNA)
  • Thymine                          Adenine
  • Cytosine                         Guanina
  • Guanine                          Cytosine

From a DNA template strand:    TACCGAT

The mRNA strand obtained is:  AUGGCUA
