What's the difference between a control and a control group in biology?

Is there any difference? If so, what?|||Basically the same thing. When you study groups lets say certain drug in mice we have the treatment group and a control group as baseline to compare to treatment to see if there is effect. So geoups you use when you use more individuals





Now control you use for example a certain gens are found in your PCR product you always use a marker or control to see if your PCR was succesful usely GADPH (household gen has to with glucose breaking down). But also when you want to test if amylase breask down starch you use one starch with amylase group and one without.





So groups you use when you have groups and controls when you compare single factors
