Coin grading. Coin grading is the process of determining the grade or condition of a coin, one of the key factors in determining its value. A coin's grade is generally determined by five criteria: strike, preservation, luster, color, and attractiveness. Several grading systems have been developed. Certification services professionally grade coins for tiered fees.
DNA is composed of repeating units called nucelotides or nucleotide bases. DNA polymerase is responsible for the process of DNA replication, during which a double-stranded DNA molecule is copied into two identical DNA molecules.NA polymerase / DNAP. DNA polymerase (DNAP) is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules. Nucleic acids are polymers, which are large molecules made up of smaller, repeating units that are chemically connected to one another.
DNA polymerase 3 is also called as holoenzyme and it is the most essential component of replisome. Difference in function. DNA polymerase 1 functions helps in DNA replication. It is used for molecular biology research. During the process of replication, an RNA primer is filled in the lagging strand of the DNA.DNA polymerase 1 removes the RNA primer and fills in the nucleotides which are necessary for the formation of the DNA in the direction- 5â to 3â.t is used for molecular biology research.
