The DNA synthesis reaction catalyzed by DNA polymerase I requires Mg2+, which is a cofactor for catalysis, and the four deoxynucleoside triphosphates (dNTPs), which are the monomeric building blocks for the growing polymer. … DNA polymerases cannot start synthesis on a template by simply joining two nucleotides.
What is addition polymerisation Class 12?
Addition polymerisation or chain growth polymerisation:-
This type of polymerisation is chain growth polymerisation it involves successive addition of monomer units to the growing chain carrying a reactive intermediate such as free radical a Carbocation or carbanian.
What is addition polymerization Class 8?
Addition polymerization is the process of repeated addition of monomers that possess double or triple bonds to form polymers.
What is polymerization and its two types Class 8?
A polymer is a very big molecule formed by the combination of a large number of small molecules. The small molecules which join together to form a polymer is called monomer. … Nylon fibres is made of up nylon polymer in which two different types of molecules are combined alternately to form long chains.
Is Polymer A plastic?
Plastics are a group of materials, either synthetic or naturally occurring, that may be shaped when soft and then hardened to retain the given shape. Plastics are polymers. A polymer is a substance made of many repeating units.
Why are polymers bad?
The monomers that are used to make polymers, though, are often toxic or stinky. That means that the companies that make polymers need to be very careful not to let the monomers get out before they’re made into polymers.
Where are polymers used?
Polymers are used in almost every area of modern living. Grocery bags, soda and water bottles, textile fibers, phones, computers, food packaging, auto parts, and toys all contain polymers. Even more-sophisticated technology uses polymers.
What is ideal polymerization?
An ideal chain (or freely-jointed chain) is the simplest model to describe polymers, such as nucleic acids and proteins. It only assumes a polymer as a random walk and neglects any kind of interactions among monomers.
