PPT-Summary of the steps leading from gene to protein in

eucaryotes and bacteria The final level of a protein in the cell depends on the efficiency of each step and on the rates of degradation of the RNA and protein molecules A In eucaryotic cells the RNA molecule produced by transcription alone sometimes referred to as the primary transcript would contain both coding .

In a day and age where people have busier lifestyles, where obesity is becoming a trend, and homes becoming smaller – manufacturers have created an empire surrounding quick and easy meals, snacks, and even drinks. More people prefer instant gratification, which led to wanting things done in an instant – instant messaging, instant coffee, instant noodles, and even instant meals! Dynamic modeling.
