Figure 1 represents pаrt оf а prоcess thаt оccurs in eukaryotic cells. There are untranslated regions (UTR) in this sequence. At the top of the diagram is a line marked out into 7 segments. From left to right, the segments are labeled: 5 prime U T R, Exon 1, Intron 1, Exon 2, Intron 2, Exon 3, 3 prime U T R. Three arrows extend down from this top line. One arrow extends from Intron 1 in the top line to a line segment the size of intron 1 that is labeled as Intron 1. A second arrow extends from Intron 2 in the top line to a line segment the size of intron 2 that is labeled Intron 2. A third arrow extends from the top line to a line at the bottom of the diagram. The far left end of the bottom line has the label 5 prime cap followed by a small circle. Following this the line is then marked out into 6 segments that are labeled from left to right: 5 prime U T R, Exon 1, Exon 2, Exon 3, 3 prime U T R, Poly A Tail. Figure 1.
