Multiple Choice
Which of the following sequences would you expect to find in a processed eukaryotic mRNA?
A
Promoter sequence
B
Introns
C
5' cap
D
Origin of replication
Verified step by step guidance
1
Understand that a processed eukaryotic mRNA is a mature mRNA that is ready for translation.
Recall that a mature mRNA in eukaryotes has undergone several processing steps, including the addition of a 5' cap, splicing to remove introns, and the addition of a poly-A tail.
Identify that the promoter sequence is part of the DNA and is not present in the mRNA.
Recognize that introns are non-coding sequences that are removed during RNA splicing, so they are not present in the processed mRNA.
Note that the origin of replication is a DNA sequence involved in DNA replication and is not part of mRNA. Therefore, the 5' cap is the correct feature found in processed eukaryotic mRNA.
