Place the steps of transcription in order:

1. rna polymerase attaches to the dna template

2. the mrna strand moves out of the nucleus

3. base pairing forms mrna

4. the dna strand separates

4. The DNA strand separates

1. RNA polymerase attaches to the DNA template

3. Base pairing forms mRNA

2. The mRNA strand moves out of the nucleus

Explanation:

To form an mRNA, enzymes will break down the hydrogen bridges that bind the nitrogenous bases of DNA. Then, following the 5'a3 'DNA code, the RNA polymerase will fit the nucleotides that make up the RNA.

But stay tuned! RNA has no thymine (T), so when RNA polymerase encounters an adenine (A) it will fit into a uracil (U).

In RNA formed from DNA there is the formation of codons, which are nothing but groups of three nitrogenous bases that form a code for a given amino acid (remember that RNA is involved in protein synthesis and amino acids are the monomers). that make up these molecules).

Some parts of the RNA produced are not coding, that is, they will not be used to produce proteins. These parts are called introns. The regions that will be expressed are called exons.

Once formed, the RNA molecule will undergo a maturation process where the introns will be removed.

In summary, we can state that transcription occurs in the following steps:
