Question

RNA is a part of many cellular processes, particularly those associated with protein synthesis: transcription, RNA processing, and translation. Match them to identify the step in protein synthesis where each type of RNA is utilized. If an RNA is produced in one process, and then utilized in another process, choose the process in which it is utilized. If an RNA does not play any role in protein synthesis, then label it "not used in protein synthesis".
pre-mRNA, mRNA, rRNA, RNA primers, snRNA

a. transcription/RNA processing
b. translation
c. not used in protein synthesis

Answer 1

Answer:

a. transcription/RNA processing : pre-mRNA, snRNA

b. translation : mRNA, rRNA,

c. not used in protein synthesis: RNA primers

Explanation:

pre-mRNA, mRNA, rRNA, RNA primers, snRNA

a. transcription/RNA processing : pre-mRNA, snRNA

b. translation : mRNA, rRNA,

c. not used in protein synthesis: RNA primers

The pre mRNA the product after transcription from the DNA is processed eg by addition of poly A tail, splicing etc before undergoing the process of translation, the snRNA also help in performing this function. In translation, the mRNA is trnslated to proteiin in the ribosomes which is also made up of rRNA and proteins. RNA primers is not needed in any of these two, only i DNA replication as the DNA polymerase is uable to begin the synthesis of adding nucleotides to a DNA strand.
