Which if the following is not part of RNA processing?
Addition of a 5' cap
Splicing out of introns
Pairing of the codon and anticodon
Addition of a poly-A tail
2.An mRNA molecule that contains the genetic information to translate only a single peptide is considered to be...
Homework Answers
1. Among the four points given in the tables the point that is not a part of RNA processing is splicing out of introns because splicing is done in order for the mRNA to encode a protein with the right sequence nd not related with RNA processing.
2. An mRNA molecule that contains the genetic information to translate only a single peptide is considered to be a monocistronic.

Question 3 Which of the following statements about RNA splicing is false? Small RNA molecules in the nucleus participate in the splicing reactions necessary for the removal of introns. Splicing occurs after the cap has been added to the end of the mRNA Formation of the lariat intermediate is dependent on the 3' OH. Splicing can remove coding as well as non-coding sequence.
