Read the information for transcription and then answer the question. Protein Synthesis

Explain the process of transcription

Protein synthesis is the process which synthesizes proteins by the information coded in the DNA molecule with the help of two distinct process takes place in order namely transcription and translation.

Transcription is the first process of the central dogma or the protein synthesis that produces mRNA molecule that carries all the information stored in the DNA molecule out of the nucleus (in eukaryotes only) to the ribosome where the second process Translation takes place.

Untwists then unzips of DNA molecule is catalyzed by RNA polymerase result in the Hydrogen-bonds between the strands break .

Creates complementary base pairs with bases of the DNA strand with help of free RNA nucleotides

weak hydrogen bonds and sugar-phosphate bonds form between base pairs and RNA nucleotides  respectively

mRNA strand is synthesized  and peels off the DNA and transported or pass from the nucleus to cytoplasm

substitution is the answer in this case

well, i believe that the answer is 2. : 3
