What are the monomers of polymerase?

What are the monomers of polymerase?

When DNA is in its polymerized form, the monomers are deoxyribonucleoside monophospates (dNMPs). This means that each nucleotide that is layed down by DNA polymerase must first have two of its phosphates hydrolyzed (beta and gamma).

Is DNA polymerase a monomer or 3 dimer?

The DNA Polymerase III Holoenzyme: An Asymmetric Dimeric Replicative Complex with Leading and Lagging Strand Polymerases.

What is dimer in RNA polymerase?

Dimerization of RNA polymerase I (Pol I) has emerged as a mechanism to repress the synthesis of ribosomal RNA (1). Pol I dimers can be isolated from Saccharomyces cerevisiae extracts and are inactive in transcription (2).

Is DNA polymerase a dimer?

The DNA polymerase III holoenzyme: an asymmetric dimeric replicative complex with leading and lagging strand polymerases. Cell.

Is cellulose A monomer or polymer?

Cellulose is a linear polysaccharide polymer with many glucose monosaccharide units. The acetal linkage is beta which makes it different from starch. This peculiar difference in acetal linkages results in a major difference in digestibility in humans.

What are the 4 nucleotide monomers?

The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T).

Does DNA polymerase 3 have polymerase?

DNA polymerase III (polIII) holoenzyme of Escherichia coli has 3′—-5′ exonuclease (“editing”) activity in addition to its polymerase activity, a property shared by other prokaryotic DNA polymerases. The polymerization activity is carried by the large alpha subunit, the product of the dnaE gene.

Is RNA polymerase a monomer?

The fraction contributing the RNA polymerase I (pol I) activity consists of dimeric and monomeric pol I under conditions optimal for in vitro transcription. The capability to utilize the ribosomal gene promoter correlates with monomeric pol I complexes which are possibly associated with further transcription factors.

Is galactose a polymer?

Galactan is a polymeric form of galactose found in hemicellulose, and forming the core of the galactans, a class of natural polymeric carbohydrates.
