Answer:
Messenger RNA, or mRNA, leaves the nucleus through pores in the nuclear membrane. ... During mRNA processing, the introns (non-coding regions) of the pre-mRNA are removed, and the exons (the coding regions) are spliced together. Additionally, a 5' cap and a 3' poly A tail are added to the pre-mRNA
Explanation:
Answer:
phenotype
Explanation:
Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
Prokaryotic protein synthesis can be fairly fast because one gene can be transcribed and translated simultaneously. Eukaryotic synthesis is slower, but more precious. They can "check" the mRNA before it is translated into protein.
