What helps lower the error rate in DNA replication to 1 in 1 billion nucleotides?

They are the DNA repair system, which lowers the error. They are broadly of two types- i) direct RS ii) extensive RS. In direct RS, only single faulty nucleotide is replaced, and in extensive, a part of DNA is replaced!

What are the special enzymes of DNA replication?
The main enzymes involved in DNA replication are: Helicase: unwinds the double helix into two strands Polymerase: adds nucleotides to an existing strand Ligase: brings together the Okazaki fragments Topoisomerase: cuts and rejoins the helix RNA primase: catalyzes the synthesis of RNA primers Hope this helps!
What does the term viral replication refer to?
Viral Replication is a process that a virus reproduces itself in the body. The study of viral replication helps scientists understand diseases and allows them to work on ways to cure them.
what helps prevent errors in DNA replication?
DNA polymerase checks the DNA for errors.
How do eukaryotic organisms solve the problem of time constraints on replication of DNA?
The replication begins at origins along the DNA.
What is two major rules of DNA polymerase in the process of DNA replication?
One major rule of DNA polymerase is that it can only synthesize DNA in the 5' to 3' direction. This means that it adds nucleotides to the growing DNA strand by linking the 3' end of the incoming nucleotide with the 5' phosphate group of the previous nucleotide. Another rule is that DNA polymerase requires a primer, a short segment of RNA or DNA, to initiate DNA synthesis. The primer provides a starting point for DNA polymerase to begin adding nucleotides.

What is the replication of cells?
Replication of DNA <= thank you to our first charter member of the tautology club... i kid, i kid. the question is very wide in scope. from a cellular perspective, the replication of DNA is the process by which cells transfer their genetic material from one generation to another. on a slightly smaller scale, the replication of DNA is a process by which the internal mechanisms of cells match the component pieces of DNA (called nucleotides) together in rapid succession. the matching process takes place after specialized proteins in the cell bind to a strand of DNA and split the two strands of the DNA molecule. different specialized proteins match the component nucleotides as the proteins move down the strand of DNA and edit mistakes if any are made. hope this helps some.
What helps errors in DNA replication?
DNA polymerase checks the DNA for errors.
Which procedure helps to ensure that the participants in a survey are representative of a larger population?
Random sampling is a procedure that can help ensure participants in a survey are representative of a larger population. This involves selecting individuals from the population at random, giving each individual an equal chance of being chosen for the survey. Random sampling helps reduce bias and allows for generalization of survey results to the larger population.
what helps prevent errors in DNA replication?
DNA polymerase checks the DNA for errors.
What is the importance of regulating gene expression?
It helps you alloe dna replication through mRNA
What reduces errors in DNA replication?
There are an average of 6 errors for every cell division, most of which either occur in the 95% percent of DNA that does not code for proteins or are relatively unharmful substitution mutations.
Why is the use of zero-error necessary in a measuring instrument?
The zero error helps in correcting the misreading you get from any instrument. It helps in maintaining the sensitivity of the instruments.
Which enzyme is the key player in replication?
In prokaryotes: DNA gyrase - a topoisomerase II protein that introduces negative supercoils in the DNA to reduce torsional stressDNA helicase - breaks the hydrogen bonds between nucleotides and unzips the DNA double helixSingle stranded binding proteins - stabilize DNA be keeping the DNA strands from reannealingDNA Polymerase III - polymerizes nucleotides forming a new DNA strandLoading clamp - loads the DNA strand into pol IIIDNA Primase - lays down an RNA primer on the lagging strandDNA Polymerase I - replaces RNA primer with DNADNA Ligase - ligates DNA strand together on the lagging strandIn eukaryotes:DNA Pol III is replaced by DNA Pol DeltaPol I is replaced by Pol AlphaRPA - replication protein A replaces the SSBsRFC - replication factor C replaces DNA loading clampPCNA replaces the beta subunit
How do eukaryotic organisms solve the problem of time constraints on replication of DNA?
The replication begins at origins along the DNA.
What is 1 percent of 5 billion dollars?
