Step-by-step explanation:

Transcription is a process in which an RNA Polymerase (enzyme) "reads" a template strand of DNA in the 3'-5' direction*, creating an antiparallel RNA strand from it.

* Even though the template strand of DNA is read in the 3'-5' direction, the RNA that is being synthesised is in the 5'-3' (as to follow anti-parallelism).

Both DNA and RNA are constituted by nitrogenous bases, amongst other things. The letters in the sequences we're working with here represent nitrogenous bases.

DNA has the follow nitrogenous bases:
Guanine (G), Cytosine (C), Thymine (T) and Adenine (A), which pair-up as G-C and T-A.

RNA is similar, but with a slight difference:
Guanine (G), Cytosine (C), Uracil (U) and Adenine (A), which pair-up as G-C and U-A.


Since no direction indicators are given, we'll just read the DNA sequence from left to right:

GTTACC
