Determine the concentration of monocytogenes enumerated from the apple slice based on the information below. You must draw your serial dilution and show your mathematical calculation to receive full credit. The apple slice (12 g) was first mixed with 108 ml of sterile 0.1% peptone water. After, 1 ml was added to tube containing 9 ml of sterile 0.1% peptone water. Process was repeated with two additional tubes. 1 ml was pipetted from tubes 2 and 3 onto MOX media. Plates were incubated at 37 for 48 hours. The pictures below show the plates from tube 2 (left) and tube 3 (right).
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.
