Which of the following is a function of the DNA polymerase I enzyme of E coli?
E. coli DNA Pol I consists of four domains with two separate enzymatic activities. coli DNA Pol I because its main function is associated with DNA repair, rather than replication. DNA polymerase is mainly used in base excision- repair and nucleotide-excision repair.
What are the 3 basic steps of DNA replication?
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
What is DNA replication process?
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
What is the function of DNA synthesis?
Copying the Recipe of Life As the cell divides to become two, the DNA has to be copied so that both cells contain the necessary genetic information. The synthesis, or making of new DNA strands in living cells is referred to as “DNA replication”.
