Alcohol fermentation produces carbon dioxide gas as a by-product, and this is why alcohol fermentation is more suitable for baking. Alcohol fermentation occurs when breads are made. The carbon dioxide gas is what creates tiny air bubbles within the dough and makes bread be the light consistency we are used to. In contrast, bread made without yeast (alcohol fermentation) is very flat.

Answer:
The correct answer is B) Transcription, 5' cap addition, addition of poly-A tail, exon splicing, passage through nuclear membrane.
Explanation:
The transcription process in eukaryotes takes place in the nucleus of the cell and after transcription post-transcriptional modification also takes place in the nucleus which is necessary to guide the mRNA out of the nucleus.
First, the process of transcription takes place in which DNA is transcribed to mRNA by an enzyme called RNA polymerase. After transcription post-transcriptional modifications takes place in the given order.
1. Capping: In capping process 7-methylguanosine is added by capping enzyme at 5' end of mRNA.
2. Polyadenylation: In polyadenylation, many poly-A residues are added at the 3' end of the mRNA called the poly-A tail.
3. Intron splicing: Introns are the non-coding sequence present in mRNA which are spliced out of mRNA and all exons are joined together.
After these post-transcriptional process, the mature mRNA is transported out of the nucleus through the nuclear membrane.
What are your options, if you have any?
I know they both need each other in order to function, but I dont know if thats the answer needed, or if its more complicated than that..
hope I could help atleast a bit!
