Which of these is the function of a poly (A) signal sequence? A. It adds the poly (A) tail to the 3' end of the mRNA BR codes for a sequence in eukaryotic transcripts that signals termination of transcription-10-35 nucleotides away C. It allows the 3' end of the mRNA to attach to the ribosome D is a sequence that codes for the hydrolysis of the RNA polymerase It adds a 7-methylguanosine cap to the 3' end of the mRNA

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.
