Out of the 4 base pairs that are shown, B and C are the ONLY Watson-Crick base pairs that are found in BOTH DNA and RNA The base pair seen in B is more stable than the Watson-Crick base pair shown in C partly because of a larger number of hydrogen bonds and partly because of more favourable pi-stacking interactions with adjacent base pairs. The base pair shown in D is almost never found in the DNA double helix. because the extra space occupied by the two purine bases would severely distort the helical structure normally generated by base pairs involving a pyrimidine base and a purine base. The base pair formed in A is less stable than the Watson-Crick base pair shown in B partly because of a smaller number of hydrogen bonds and partly because of less favourable pi-stacking interactions with adjacent base pairs.

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.
