A specific recognition sequence identified by endonucleases to make cuts at specific positions within the DNA is:
Plasmid $\mathrm{pBR}322$ has PstI restriction enzyme site within gene ${\mathrm{amp}}^{R}$ that confers ampicillin resistance. If this enzyme is used for inserting a gene for $\beta$-galactoside production and the recombinant plasmid is inserted in an E. coli strain
During the process of gene amplification using PCR, if a very high temperature is not maintained in the beginning, then which of the following steps of PCR will be affected first?
Which of the following is a correct sequence of steps in a PCR (Polymerase Chain Reaction)?
Which of the following is not an application of PCR (Polymerase Chain Reaction)?
DNA strands on a gel stained with ethidium bromide when viewed under UV radiation, appear as:
During the purification process for recombinant DNA technology, addition of chilled ethanol precipitates out:
