Answer:
Transcription begins in the nucleus when RNA polymerase unzips a DNA molecule.
RNA nucleotides align themselves to complementary base pairs and in this manner messenger RNA is formed.
In eukaryotes must be processed before it leaves In the nucleus.
One end is modified with the addition of a cap and the other end is modified with the addition of a poly-A tail. Some sections called introns are edited out, leaving only exons remaining.
Then, the messenger RNA leaves the nucleus and enters the cytoplasm where it awaits the process of translation
Step-by-step explanation:
Transcription is the process in which DNA becomes RNA. In this protein synthesis, transcription occurs in the nucleus while translation in the cytoplasm. In the first one, which is transcription, a messenger RNA is produced. In the seceond one, an amino acid sequence is produced in the ribosomes.
*Take into account there were two options missing that I added because they were the only correct answer. "In eukaryotes must be processed before it leaves In the nucleus" the only right answer is eukaryotes, because prokaryotes don't have nucleus. The other situation was in "Then, the messenger RNA leaves the nucleus and enters the cytoplasm where it awaits the process of translation" the only option given was "transcription". The right answer is "translation" because this one occurs in the cytoplasm, and transciptrion in the nucleus.
