The term "codon" refers to Multiple Choice a three-nucleotide sequence of DNA that codes for a protein. an amino acid that is coded for by three bases of DNA. a three-base sequence of mRNA. the part of a rRNA molecule where a new amino acid is added. the part of tRNA that is a triplet of bases that forms hydrogen bonds with complementary sequences.
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.
