Which of the following statements best explains why there are many more codons than there are amino acids? Group of answer choices Many codons are now considered "junk" codons The rules for base pairing between the third base of a codon and tRNA are flexible. Some tRNAs have anticodons that recognize four or more different codons. The DNA codes for all 61 tRNAs, but some are then destroyed.

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.
