What is a nucleic acid probe quizlet?
What is a nucleic acid probe quizlet?
Nucleic Acid Probe (DNA probe), is a sole strand of DNA that is tagged with a radioactive or fluorescent substance, and binds particularly to a corresponding DNA sequence. It is used to identify its integration through fusion with another DNA sample.
What are nucleic acid probes used for quizlet?
a nucleic acid probe can be used to identify unknown bacteria or viruses in clinical samples.
What purpose does a nucleic acid probe serve?
What purpose does a nucleic acid probe serve? It helps identify genes that have been inserted into bacterial plasmids.
What is a probe in molecular biology quizlet?
What is a probe in molecular biology? A probe is a labeled single strand of DNA or RNA used to locate its complementary sequence.
Which of the following will hold a larger insert of foreign DNA requiring smaller numbers of cultures to represent the entire genome?
A phage particle holds a much larger insert of foreign DNA compared with a plasmid vector, thus requiring a much smaller number of cultures to fully represent the entire genome of the original organism.
What is a DNA probe a level biology?
A DNA probe is a short length of single-stranded DNA that has a known base sequence complementary to the specific base sequence of a known allele. The probe is usually attached to a radioactive or fluorescent label that indicates its position.
Why are plasmids essential for recombinant DNA technology?
Why are plasmids essential for recombinant DNA technology? DNA from a gene of interest can be inserted into a plasmid, then the modified plasmid can be inserted into a bacterial cell to replicate a gene of interest many times. It is a thermostable protein that can withstand the heat needed to denature the DNA strands.
What is a probe quizlet?
A probe is a slender instrument with a blunt end designed for examination of the depth and topography of an area.
How are plasmids used in biotechnology quizlet?
Plasmids serve as cloning vectors since carry the gene of interest into a bacteria for replication and expression. These enzymes are found in bacteria and protect the bacteria against intruding DNA from other organisms and phages.
How does a gene probe work?
A probe is a single-stranded sequence of DNA or RNA used to search for its complementary sequence in a sample genome. The probe is labeled with a radioactive or chemical tag that allows its binding to be visualized. In a similar way, labeled antibodies are used to probe a sample for the presence of a specific protein.
What property of DNA makes it possible for a probe?
Hello Kylie, Every DNA/RNA base, A C G T and U, has only one possible pairing partner, so if the strand is open on one side (single strand), the opposite side can be inferred because only one sequence will match the existing strand’s base sequence. This property is usually called the Base Pairing property.
What is automation quizlet?
automation. the use of technology to ease human labor or to extend the mental or physical capabilities of humans. controller. in robotics, a tiny computer that acts as the robots brain and contains the computer program.
