For each of these things, say whether it describes the coding sequence or the regulatory sequence. The ______________ sequence determines the order of a protein’s amino acids. The ______________ sequence attaches to transcription factors. The ______________ sequence is where RNA polymerase attaches to start transcription. The ______________ sequence includes the start and stop codons. The ______________ sequence allows the gene to be activated in some cells but not others.
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.

Coding sequences are sequences or portions of a gene or mRNA which codes for a protein. The coding region of a gene is also known as coding DNA sequence (CDS).
Regulatory sequences are sequences of a nucleic acid which regulate or control the expression of genes in an organism.
