A PCR machine works by repeatedly heating and cooling a sample containing DNA. This process, called thermal cycling, allows specific DNA sequences to be copied, or amplified, many times. The machine also includes a detector that can identify the presence of the amplified DNA sequences, providing a way to detect and analyze specific genetic material.

What are the rt pcr?
RT-PCR stands for reverse transcription polymerase chain reaction. It is a molecular biology technique used to amplify and detect specific RNA sequences by first converting RNA to complementary DNA (cDNA) using reverse transcriptase enzyme before amplifying the cDNA using PCR. RT-PCR is commonly used to quantify gene expression levels, detect viral infections, and diagnose genetic diseases.
How does lamp isothermal amplification work to detect specific genetic sequences in a sample?
Lamp isothermal amplification is a molecular biology technique that rapidly amplifies specific genetic sequences in a sample. It works by using a set of primers that target the desired genetic sequence and a DNA polymerase enzyme that replicates the DNA at a constant temperature. This process results in the exponential amplification of the target sequence, making it easier to detect and analyze.
Which best describes the purpose of the polymerase chain reaction (PCR)?
Polymerase Chain Reaction is widely used in many areas to identify DNA and detect infectious organisms or genetic variations, including the viruses that cause AIDS, hepatitis, and tuberculosis, detection of mutations in human genes, and numerous other tasks.
Difference between southern and northern blotting?
Southern blotting is used to detect specific DNA sequences, while northern blotting is used to detect specific RNA sequences. Southern blotting involves DNA samples being digested with restriction enzymes, separated by gel electrophoresis, and then transferred to a membrane for probing. Northern blotting involves RNA samples being separated by gel electrophoresis, transferred to a membrane, and then probed with a complementary RNA or DNA sequence.
How is FISH Technology used?
FISH (Fluorescence In Situ Hybridization) technology is used to detect and visualize specific DNA sequences in cells by using fluorescently labeled DNA probes that bind to complementary target sequences. It is commonly used in medical diagnosis, genetic research, and cancer detection to analyze chromosomal abnormalities and gene expression levels. FISH technology allows for precise and sensitive detection of specific DNA sequences within the cell.
What does the medical abbreviation PCR mean?
PCR stands for "polymerase chain reaction," which is a molecular biology technique used to amplify and detect specific DNA sequences. It is commonly used in medical diagnostics and research to detect viruses, bacteria, and genetic mutations.

What is allele specific associated primer?
An allele-specific associated primer (ASAP) is a primer designed to specifically amplify a particular allele of a gene while discriminating against other alleles. It is commonly used in techniques such as allele-specific PCR to selectively amplify and detect a specific variant or mutation. ASAPs can be designed based on single nucleotide polymorphisms (SNPs) or other genetic variations to target a specific allele of interest.
What is difference between DNA probe and primer?
A DNA probe is a single-stranded DNA sequence used to detect complementary sequences, whereas a primer is a short single-stranded DNA sequence used to initiate DNA synthesis during PCR. Probes are used to identify specific sequences in a sample, while primers are used to amplify a specific target sequence.

If youre using an up to date light microscope to examine animal cells you wont be able to detect what?
You won't be able to detect specific proteins or molecules within the cell, such as individual enzymes or DNA sequences. These require more advanced techniques like immunofluorescence or fluorescence in situ hybridization for detection.
What is target gene enrichment?
Target gene enrichment is a technique used in molecular biology to selectively amplify and analyze specific genes or regions of genomic DNA. This allows researchers to focus on particular genes of interest, making it easier to detect and study specific genetic variations or mutations that may be relevant for a particular study or condition.
What are radioactive probes?
Radioactive probes are molecules that are labeled with a radioactive isotope, such as ^32P or ^35S, which emit radiation that can be detected. They are commonly used in molecular biology to detect specific DNA, RNA, or protein molecules by binding to complementary sequences and producing a signal that can be visualized.
How can PCR help to detect very low amounts of DNA?
PCR can amplify a small amount of DNA to detectable levels through multiple cycles of replication. By targeting specific DNA sequences and repeatedly copying them, PCR enables the detection of even trace amounts of DNA in a sample. This technique is highly sensitive and can be used to identify and quantify low levels of DNA, making it a valuable tool in forensic, medical, and research applications.
