Once a primary RNA transcript is created from a DNA template, it must be modified in several ways before becoming messenger RNA (mRNA), ribosomal RNA (rRNA) or transfer RNA (TRNA). The following image shows RNA processing of one pre-mRNA into mRNA. Note that pre-RNA is processed in three ways: 1) a 5' methylguanylate cap (G cap) is added, 2) a poly-A tail is added, and 3) the spliceosome removes introns from the pre-mRNA transcript. Please redraw the following diagram and label the following on your diagram: DNA Promoter pre-mRNA (unprocessed) mRNA *5' methylguanylate cap *polyadenylation *Exon (may be more than one) *Intron (may be more than one) Transcription RNA processing AAAAA PART C: FOLLOW-UP QUESTIONS 1. Why is a poly-A tail important?: 2. What do introns do? Why do they exist in eukaryotes when they are mostly absent in prokaryotes? 3. What do you think 'alternative splicing' means, and how might it expand the function of a gene?

Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.

Transcribed Image Text:Once a primary RNA transcript is created from a DNA template, it must be modified in
several ways before becoming messenger RNA (mRNA), ribosomal RNA (rRNA) or
transfer RNA (TRNA). The following image shows RNA processing of one pre-mRNA
into mRNA. Note that pre-RNA is processed in three ways: 1) a 5' methylguanylate cap
(G cap) is added, 2) a poly-A tail is added, and 3) the spliceosome removes introns from
the pre-mRNA transcript. Please redraw the following diagram and label the following

Expert Solution
Step 1
The Central Dogma controls the features of the DNA to Rna and RNA to proteins. This includes the process of transcription and translation. However during these events other events may also take place which is termed as post transcriptional modification.
