Question

Eukaryotic messenger RNA can undergo post synthetic processing after transcription and before translation. One of the processing steps is splicing, where portions of the RNA are removed and the remaining RNA are joined together. Classify the statements regarding mRNA splicing as true or false. True statements False statements

Answer 1

Answer:

Statements that are true are:

B) in splicing, intron sequences are removed from the mRNA in the form of lariats (loops), and are degraded = TRUE

C) one mRNA can sometimes code for more than one protein by splicing at alternative sites = TRUE

E) splicing occurs while the mRNA is still in the nucleus = TRUE

Statements that are false are:

A) splicing occurs while the mRNA is attached to the nucleosome = FALSE

D) splicing of mRNA does not involve any proteins = FALSE
