Answer:

Transcription

Step-by-step explanation:

This occurs in three steps itself: initiation, elongation, and termination

Initiation (beginning)

- RNA polymers bind to a promoter on a gene

- DNA then unwinds to be "read" by an enzyme

- DNA now ready to make mRNA strand

Elongation (Second step)

- nucleotides are added to mRNA strand

- mRNA molecule is built after RNA polymers reads the DNA that unwound

- adenine (A) in DNA connects to a uracil (U) of RNA while connected to each other

Termination (End)

- RNA will cross a stop sequence in the gene (termination)

- mRNA done and disconnects or detaches from DNA

Hope this helps!
