For the following characteristics, state whether they are true for the 5' CAP, the Poly-A tail, BOTH modifications, or NEITHER modification. Briefly (1 sentence) support your answer. Promotes translation of the mRNA at the 3' end. Acts to prevent degradation of the mRNA by exonucleases. Promotes splicing of the mRNA. Promotes binding of transcription factors to the Mediator complex.
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.
