Biology class Memes

The biology exam question asks what gives blood its red color, with the correct answer being hemoglobin (option B). But someone snuck in "communism" as option E, playing on the classic "red = communism" association! The bottom image shows a Soviet soldier with red blood cells superimposed on his face declaring "I serve the Soviet Union" - as if the red blood cells themselves are loyal communist comrades! The iron in hemoglobin might be abundant, but apparently our red blood cells have been serving the communist agenda this whole time! Biology teachers everywhere are both facepalming and secretly giggling at this one.

The eternal struggle of molecular biology students captured in one perfect image! DNA guy is hunched over his notes with the intensity of someone trying to remember all 3 billion base pairs of the human genome before the exam. Meanwhile, RNA is just chilling in the back like "I'm just the messenger here" with that perfect slacker energy. Classic case of DNA doing all the hard genetic coding work while RNA gets to be the fun, single-stranded party molecule that gets to leave the nucleus whenever it wants. The biological equivalent of the responsible older sibling vs. the one who "lives in the moment."
