When mRNA was discovered, Francis Crick proposed the Adaptor Hypothesis. He predicted that there would be a set of adaptor molecules which recognized a specific nucleotide sequence on one end and a specific amino acid on the other end. 1A. Is there such a set of adaptor molecules? What are they called? 1B. How do these adaptor molecules recognize specific nucleotide sequences? 1C. How do these adaptor molecules recognize specific amino acids? If they do not recognize specific amino acids, how do specific amino acids become attached to specific adaptor molecules?
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.
