Question: Eukaryotic mRNAs that have not been spliced can be translated. True/False
Option 1: True. This statement is misleading because in eukaryotic cells, pre-mRNA transcripts that have not undergone splicing are generally not exported from the nucleus to the cytoplasm where tr......Login to view full explanation登录即可查看完整答案

In eukaryotes, what does the mRNA transcript contain?
In eukaryotic cells, the initial RNA transcript (pre-mRNA) contains non-coding segments called [ Select ] spliceosomes promoters exons introns polymerase that intervene between coding regions. Before the RNA leaves the nucleus, a large protein-RNA complex called the [ Select ] introns polymerase exons ribosomes spliceosomes removes these non-coding parts and joins the coding regions, known as [ Select ] promoters spliceosomes polymerase exons introns together. This process allows a single gene to encode multiple different proteins depending on which segments are treated as coding.
