What are the consequences of having thymine dimers formed in DNA? They prevent the transcription of the DNA into RNA. They create an apurinic site. They form an extra phosphodiester bond between themthat is difficult to repair. They cause double-stranded DNA breakage. They distort the DNA structure and result in errors during DNA replication.

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.
