How does the structure of DNA allow cells to replicate? How does DNA polymerase proofread? What is the result of DNA replication? How do mesosomes help in DNA replication? What is accomplished by DNA replication? How are the leading and lagging strands identified in DNA replication?
Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (antiparallel) directions. The beauty of this structure is that it can unzip down the middle and each side ...
Synthesis of DNA by DNA polymerase occurs in the 5' to 3' direction. Due to the anti-parallel nature of DNA strands, the template strand used to guide...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our...
How Polymerase Chain Reaction Works Gene copies are made using a sample of DNA, and the technology is good enough to make multiple copies from one single copy of the gene found in the sample. PCR amplification of a gene to make millions of copies, allows for detection and identification of ...
Have your DNA (and eat it, too) EQ: How do genes and chromosomes work together to determine an organism’s traits? Questions How would you explain the concept of complementary bases to a friend? In your own words, describe DNA replication What is the most important reason for DNA replicati...
When origin sequences are incubated in the presence of RNA polymerase, two main transcripts can be identified (Figure 1). The longer one (RNA2) starts from a promoter 550 nucleotides upstream from the replication origin and is believed to form a hybrid with the DNA template in the origin ...
DNA replication fidelityDNA polymerase mutantMutationrateExonucleaseLow fidelityHigh fidelityWe conclude that the use of herpesvirus fidelity mutants allows unprecedented insights into virus evolution driven by low-fidelity replication. More than that, their use allows us to observe accelerated evolution, ...
The ability to carry out its function is rooted in the DNA polymerase’s structure, often likened to a hand with three parts: the palm, the thumb, and the fingers, each carrying out critical functions. Given their role in enabling replication, these polymerases are critical targets of ...
We used solid phase polymerase chain reaction (spPCR) to replicate the DNA and a cavity chip to maintain the spatial order in our DNA microarray copying process. In a first spPCR the DNA from the original DNA array is copied into cavities (Fig. 1a–c) and in a second spPCR the DNA ...
If a DNA replication error is detected by DNA polymerase, how is it corrected? An individual inherits two defective copies of the MLH1 gene, a protein involved in mismatch repair of DNA during its replication. What do you predict will be the consequences of defic...
