Chapter 14.3, Problem 4C
Summary Introduction
To draw: A simple sketch illustrating how alternate splicing can give rise to different proteins.
Introduction: In eukaryotes, transcription occurs in the nucleus, and pre-mRNA is synthesized. This pre-mRNA is further modified before translation in the cytoplasm. This is known as RNA processing. It includes the modification of mRNA ends and RNA splicing. During RNA splicing, the non-coding regions, that is introns, are excised from the RNA molecules, and the coding regions are joined.

1Need help:. draw valine-aminoacyl tRNA synthetase. Show the
tRNAs and the valine amino acid. You can use the one-letter code for valine (V) and do not have to draw
the amino acid structure. Label the tRNA and amino acid binding sites on the enzyme.
Explain the function of valine-aminoacyl tRNA synthetase and explain why there are 20 related enzymes
in every cell.
