In today's post, we will be going over the last universal feature of all cells, as described by Alberts et al. First, I would like to mention that I just added an image to go with my last post, in order to simplify the concept of the phospholipid bilayer for you. With that, the final point to be discussed on this topic, per Alberts et al. is the following:
This point is truly as simple as it sounds. There is not much to discuss here, but I will give an example to hopefully bring the point home. As a note that is useful to remember, it is thought that cells can exist in a living state with no less than probably 300 genes. Also, only approximately 60 genes exist fundamentally as genes shared by all living species (Alberts et al. 2014).
A good example of an uncomplicated cell is known as Mycoplasma genitalium, which is actually parasitic in mammals. To showcase is simplicity, it has approximately 530 genes, and about 400 of those are actually essential. Its entire genome consists of 580,070 nucleotide pairs amounting to what is 145,018 bytes of information in total. This is comparable to a single chapter of a biology textbook! All in all, cell biology is not impossibly complicated, despite our notions about the subject (Alberts et al. 2014).
