Ever wonder what gives our body the "assembly instructions"? How it figures out what it needs to build those billions of cells? Well, longtime subscribers and just well-informed people know the answer - all the information is hidden in the genome. But do you know how many genes are in it? Hardly😏 So, we tell you! There are about 25,000 genes in the human genome, that is - 25,000 instructions to create a functioning and thinking body! Each of them is responsible for assembling a certain "piece" of the body. For example, 858 of them describe the process of creating olfactory neurons. At the same time, 468 of them are pseudogenes - their ancient functions are disabled as a result of some mutation that deprived them of the ability to synthesize proteins. This explains why humans, despite the fact that the sense of smell plays a strategic role in their lives, do not smell as keenly as other mammals🤔
