Considering the gluconeogenesis that may occur after removal of the amino group from amino acids, will malate be an intermediate in all such metabolic routes between amino acids and glucose? Explain. The phosphoenolpyruvate carboxykinase (PEPCK) gene is more actively transcribed when glucagon is present in blood. Putting the signal cascade responsible for that activation aside for the moment, will the reaction that PEPCK mediates be in zero or first order for that increased transcription to have a maximal affect on gluconeogenesis? Explain.

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.
