what is the function of dna polymerase brainly?
449508
The main function of DNA polymerase is to make DNA from nucleotides, the building blocks of DNA. There are several forms of DNA polymerase that play a role in DNA replication and they usually work in pairs to copy one molecule of double-stranded DNA into two new double stranded DNA molecules.

DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. ... Most prominently, DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand. DNA replication occurs during the S-stage of interphase.

DNA polymerase 3 is a component of the replisome and hence helps in replication. Summary: DNA polymerase 3 is essential for the replication of the leading and the lagging strands whereas DNA polymerase 1 is essential for removing of the RNA primers from the fragments and replacing it with the required nucleotides.

DNA polymerase III adds DNA nucleotides to the primer(s), synthesizing the DNA of both the leading and the lagging strands. What are the two enzymatic activities of DNA polymerase III? Its 5'-3' polymerase activity allows it to add new nucleotides in the 5'-3' direction.

RNA polymerase does not play a role in DNA replication, it plays a role in DNA transcription. RNA polymerase makes mRNA from DNA.

RNA polymerase (green) synthesizes RNA by following a strand of DNA. RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. ... RNA polymerases have been found in all species, but the number and composition of these proteins vary across taxa.

Just as helicase is responsible for unwinding the DNA strand, DNA polymerase is responsible for replicating the strand once it unwinds and separates. ... As the DNA strand separates, the DNA polymerase matches nucleotide bases that are missing when the strand separates.

Taq Polymerase is Preferred Enzyme for Polymerase Chain Reaction (PCR) A DNA Polymerase is a vital biological enzyme that is present in DNA replication. In the process, DNA copies into two daughter DNA molecules and synthesizes a new DNA strand from the existing strand by adding dNTPs to the growing DNA.

DNA polymerase I is a single polypeptide chain with 928 amino acids and molecular weight of 109 kDa. ... This exonuclease activity is called the proofreading or editing function of DNA polymerase I. Pol I also has a unique 5′ to 3′ exonuclease activity that is required for its DNA repair function.

In living organisms, primers are short strands of RNA. ... The synthesis of a primer is necessary because the enzymes that synthesize DNA, which are called DNA polymerases, can only attach new DNA nucleotides to an existing strand of nucleotides. The primer therefore serves to prime and lay a foundation for DNA synthesis.

RNA-Polymerase = enzyme of transcription in vivo: The transcription of the genetic information of the DNA-base-sequences into RNA-structure is performed by the DNA-dependent RNA-polymerase [1, 2]. This enzyme has been highly purified from E.

Terms in this set (47) The sole purpose of DNA replication is to generate identical DNA molecules, as they are the blueprint that makes life possible. There are reasons that there DNA replication goes through a slightly different process to repair damage.

DNA polymerase adds a new strand of DNA by extending the 3′ end of an existing nucleotide chain, adding new nucleotides matched to the template strand one at a time via the creation of phosphodiester bonds.

The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from one original DNA molecule.

In eukaryotic cells, DNA polymerases can be found in the nucleus, mitochondria and chloroplasts (mitochondria and chloroplasts have circular DNA molecules). In prokaryotic cells, the DNA polymerases are located in the cytoplasm (there aren't any compartiments).

Function. These enzymes have several functions: to remove DNA supercoils during transcription and DNA replication; for strand breakage during recombination; for chromosome condensation; and to disentangle intertwined DNA during mitosis.

DNA polymerase is the enzyme that carries in the daughter nucleotides, and DNA helicase is the one that unwinds the double helix to open the replication fork.
