When two adjacent bases in the same strand of DNA dimerize (form a covalent bond between them), what happens to the DNA?​   a. ​the original strand of DNA now contains a new DNA sequence   b. ​the original strand of DNA is prevented from opening during replication, so this section of DNA will not be replicated   c. ​the original strand of DNA is methylated, which causes the bases to mismatch   d. ​the original strand of DNA is kinked, which prevents DNA polymerase from working properly   e. ​the original strand of DNA is unaffected, so no additional mutations arise

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.
