The diagram below shows the result of alternative splicing of a given precursor mRNA in two different plant tissues: leaf and seed. Consider a single base pair insertion mutation near the middle of the DNA sequence that gives rise to the RNA region labeled exon 4. GENE VA Genomic DNA exon exon Precursor mRNA exon Transcription Alternative Splicing 5 MG MAXXA exon 5- 5 Leaf Seed Which of the following descriptions of the consequence of this mutation is accurate? OA. The insertion will make the mature mRNA longer in seed. OB. The impact of this insertion depends on which protein this is OC. The insertion will alter the reading frame in leaf but not in seed.

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.
