The gene for Receptor Z contains an unknown number of untranslated first exons that are spliced to a common exon 2" - what does it mean if a "first exon" is "spliced to a common exon 2"? Does it mean that Exon 1 is attached to Exon 2, but Exon 1 is not part of the translated protein - similar to the below schematic? mRNA Option 1: [Exon 1a][Exon 2][Exon 3].... mRNA Option 2:[Exon1b][Exon2][Exon 3] mRNA Option 3: [Exon1c][Exon2][Exon 3]
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.
