The role of RNA in the process of realizing hereditary information
Capping and polyadenylation of mRNA is called processing (post-transcriptional modification). Capping: A 7-methylguanosine residue is added to the 5" end of all eukaryotic mRNAs during processing to form a unique 5" à 5" fo

Nitriles of carboxylic acids
1. Carboxylic acid anhydrides Carboxylic acid anhydrides are products of the elimination of a water molecule from two acid molecules. 1.1. Methods for preparing carboxylic acid anhydrides Carboxylic acid anhydrides, as we have just seen (3.1), can
Hydrogen - characteristics, physical and chemical properties Hydrogen as written in chemistry
The hydrogen atom has the electronic formula of the outer (and only) electronic level 1s 1. On the one hand, in terms of the presence of one electron on the outer electronic level, the hydrogen atom is similar to alkali metal atoms. However, it, like halogens,
Polymethacrylic acid
The invention relates to chemical technology for the production of synthetic high-molecular compounds. The technical task is to develop a method for producing high-purity, finely dispersed, powdery, easily dosed anhydrous polyacrylic acid. Predlo
Types of chemical reactions in organic chemistry Electrophilic addition reactions
Hydrocarbons Lecture No. 13 The enol formed during the hydration of an alkyne cannot be isolated, since the tautomeric equilibrium is always strongly shifted towards the keto form. The rearrangement of enol into the keto form occurs due to the high polarity of the O-H bond,
Chemicals and human health
They give simple examples and explain what types of substances there are. Definition of the word “substance” Simply put, a substance can be called everything that any body consists of. In higher grades, substance is the matter that makes up the physical body, and
Chemistry - natural science
Chemistry is a natural science. Like other natural sciences, it studies a certain aspect of nature and natural phenomena. Unlike other natural sciences, chemistry pays close attention to matter. The substance is, for example, water, some
Periodic properties of elements
To understand the question of what is called the radius of an atom in modern science, let us remember what an atom itself is. According to classical concepts, at the center of the atom there is a nucleus consisting of protons and neutrons, and around the nucleus each in its own orbit
