DNA-bindung proteins DBP of normal human dermis, epidermis, horny layer and psoriatic scales represent a tissue-specific group of mostly nuclear nonhistone proteins. DBP of normal epidermis and horny layer contain four different DNases. Probably these DNases have changed their pH-optimum during keratinisation. Two DNA-polymerases with pI-values of 4. Further activity of proteins which are focussed at pH 6. The proteins represent either tissue-specific DNA-polymerases or further thymidine monophosphate incorporating enzymes.

Enzymes are the class of proteins that helps in catalyzing different biological reactions. A polymerase is one of the enzymes that synthesize nucleic acids. The DNA has all the information of an organism which it transfers from one generation to another. For that by following the central dogma process- a collective process of replication, transcription and translation, DNA forms different proteins. The mRNA has all the information to form a specific protein.

Given that ribonucleotide and mismatch incorporation rates by these replicases influence somatic and germline patterns of variation, it is important to understand the details and exceptions to this overall division of labor. These observations of replisome dynamics provide important insight into the mechanisms of eukaryotic replication and genome maintenance. The division of labor among replicative DNA polymerases replicases affects basic biological processes that influence everything from evolution to pathogenesis.

Comparison Between: DNA Polymerase Vs RNA Polymerase

The main function of a polymerase which is an enzyme is somehow similar to nucleic acid polymers like that of DNA and RNA. Polymer is a compound with repeating small molecules where it is a natural or synthetic compound that consists of large molecules made of many chemically bonded smaller identical molecules such as starch and nylon. DNA strands are well formed when the deoxyribonucleotides undergo polymerization with the help of DNA polymerases which are thought to be enzymes that hasten the polymerization process.

The traditional classification of nucleic acid polymerases as either DNA or RNA polymerases is based, in large part, on their fundamental preference for the incorporation of either deoxyribonucleotides or ribonucleotides during chain elongation. Mutation of this residue resulted in a variant enzyme now capable of acting as an RNA polymerase.

 Мне даже не сказали, что вы придете. Беккер поспешил переменить тему: - У вас на голове огромная шишка. Больно. - Да нет вообще-то. Я грохнулся на землю - такова цена, которую приходится платить добрым самаритянам.
