WebbPrimase is the enzyme that synthesizes RNA primers, oligonucleotides that are complementarily bound to a nucleic acid polymer. Primase is required because DNA polymerases cannot initiate polymer synthesis on single-stranded DNA templates; they can only elongate from the 3′-hydroxyl of a primer. WebbASK AN EXPERT. Science Chemistry Why is a primer important in DNA replication? O A. It provides the RNA required for reverse transcriptase activity. O B. It provides a 5'-phosphate for the elongation of the daughter strand. OC. It ensures the fidelity of the daughter strand. O …

Webb31 mars 2024 · When DNA is replicated, the leading strand is built as a continuous piece (due to the polymerase only being able to add itself to the 3’ end), while the lagging strand is built as a discontinuous piece. The lagging strand is built discontinuously because the DNA double helix must unwind a bit before the addition of another primer. WebbAll organisms must duplicate their DNA with extraordinary accurate before each cell division. In this teilung, we explore how an expensive “replication machine” achieves this accuracy, time duplicating DNA at rates as high as 1000 nucleotides per moment.

Most plasmids of gram-positive bacteria replicate by a rolling circle mechanism similar to that used by phage φx174. Most linear plasmids replicate by means of a mechanism that involves a protein bound to the 5′-end of each DNA strand that is used in priming DNA synthesis.

WebbDNA replication is semi-conservative. This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on …
