Define P, L, I, E based on the image below: DNA 3' template 5 Ei 2 Transcription Pre-mRNA 5 3' Cap and tail added 7-mG Poly-A Processed pre-mRNA Splicing Spliced mRNA E1 E2 Es 2015 Pearson Educabon, Inc Figure 13 HOMEWORK Chapter 13 5. Page 321 "Now Solve This" Sequence 1 Sequence 2: Sequence 2 S-CTTTTTTGCCAT-3 S-ACATCAATAACT-3' S-TACAAGGGTTCT-3 Assume the required promoter site and start codons are present. For each DNA sequence (coding strand) above, determine mRNA sequence. 42 1 1 45

Explanation / Answer

P- Promoter sequence that is used to regulate the expression of the downstream gene.

L- Leader sequence is a signal sequence that tell the cell where the translated protein need to go for functioning.

I- Introns are regions of DNA that might have a regulatory function, otherwise spliced from mRNA and are not translated.

E- Exons are the region of DNA that are translated into the proteins.
