The Tas DNA polymerase is widely used in PCR, and has been since shortly after its discovery and successful replication. PCR is used when a small sample of DNA needs to be amplified, whether for analysis or so the gene can be inserted into an organism. ...
DNA polymerase is an enzyme responsible for synthesizing new strands of DNA during DNA replication. It adds nucleotides to the growing DNA strand, using a DNA template and a primer as a starting point. DNA polymerase specifically catalyzes the formation of phosphodiester bonds between the added nucl...
What best describes the structure of DNA? What determines which proteins a cell makes? What is the role of DNA in cell differentiation? How does DNA direct protein synthesis from inside the nucleus? What are the steps of protein synthesis starting with DNA?
We recently discovered that when the expression of a gene called DNA Polymerase theta (POLQ) is reduced using siRNA, cancer cells become more sensitive to radiotherapy 1. The expression of POLQ is increased in breast, colon, gastric and lung cancer, and is associated with a poor prognosis 2-...
that gene will reach its plateau more quickly due to running out of primers, and not due to the lack of reagents, which are in excess. There should be enough nucleotides, polymerase and other reagents left for the amplification of the less abundant genes. In a...
During PCR and cycle sequencing, the DNA is first denatured (the double-stranded DNA template becomes single-stranded DNA). A subsequent annealing step allows for hybridization of the oligonucleotide primer close to the sequence of interest. In the extension...

The first step in a PCR cycle is to heat the sample to 95°C. What is the purpose of heating the sample?A.To separate the two strands of DNAB.To allow the primer to anneal to the templateC.To produce the optimal temperature for Taq dna polymerase to workD.To produce the optimal ...
