Why Hox Genes?

Submitted by imadjidov on Sun, 11/03/2019 - 18:24

Why studying the similarities and differences between hox genes is important. And why their expression is important. In the development of animals, there is a special period of embryonic similarity, during which not only the appearance of the embryos but also the expression of their genes is very conservative. The existence of this period is associated with the appearance in the evolution of stable building plans. In hox genes, the genes themselves are located on the chromosomes in order, therefore, strict, consistent activation of them is necessary in order for the body to form correctly. However, the mechanism and regulation of the Hox genes themselves remain unclear. It is clear that this process is very complex and multi-staged; non-coding RNAs are involved in it. To a complete understanding of all these processes in different animals, science is still very far away. When the basic mechanisms of gene regulation during early ontogenesis are deciphered, biologists will be able to closely address the following fundamental question, namely: why is all this necessary? Why do multicellular animals suddenly switch from maternal transcripts to their own? Incidentally, this problem has not only theoretical but also practical significance.

There are a few grammatical mistakes for instance the addition of a period between the first sentence and some unnecessary commas. I would consider looking over this paragraph to fix any grammar errors. 

The beginning of a sentence should not start with "and". Try to add tone in the paragraph to make it interesting to read!
