Proteins destined for the plasma membrane must move through the secretory pathway. What role is served by the signal recognition particle (SRP) in this process? A. The SRP is required for the binding of mRNA to the ribosome. B. The SRP binds to an amino acid sequence at the beginning of a protein. C. Like HSP90, the SRP aids in protein folding within the ER. D. The SRP is required for the protein to move from the ER to the Golgi.
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.
