If you’ve ever taken a basic biology class, this question might sound almost too easy: Are bacteria prokaryotic or eukaryotic? The straightforward answer is bacteria are prokaryotic. In fact, the very definition of a prokaryote is “an organism whose cells lack a nucleus,” and all bacteria fit this description. So, why call it a “trick … Read more
It’s fascinating to realize that every living thing – from the bacteria in your yogurt to the cells in your own body – is built from one of two basic cell types. These two cell designs are prokaryotic cells and eukaryotic cells, and they differ in some pretty fundamental ways. To put it simply, prokaryotic … Read more
Sore throats can be confusing. You might hear a doctor say “it looks like tonsillitis,” while someone else mentions “strep throat,” and you’re left wondering – what’s the difference?
