How do you put DNA sample lengths 3500 in scientific notation?
In scientific notation 3500 is 3.5*10^3
What is Gap Closure methodology?
Its a technique adopted during DNA sequencing in which while joining the contigs we find whether there is any sequence present in between the contigs or not.If there is a sequence inbetween they re sequence the ends of the DNA.If not PCR is used to close the gaps.
In what type of real life situation would the extraction of DNA be useful?
Stem cells in general benefit from being injected with DNA. DNA is used in many crimes to determine who is guilty. For instance, a rape victimcould have skin underneath her fingernails that could be used to identify the perpetrator.
If a sample of DNA contained 20 percent cytosine what percentage of guanine would be in this sample and what percentage of adenine would be in the sample explain?
Umm I'll have to say that your a retard for not knowing it so tuff nubbs who ever made this is stupid because you spelled some words wrong.. The above answer is incorrect, and on a very low evolutionary rung. The correct answer is that with the amount of data provided, it is impossible to tell. If the answer isn't known, it is best to not answer.
What is the function of primers?
RNA primers are used to initiate the DNA replication at the template strand. DNA molecules require a free 3' OH, to which it could add the nucleotides. This free 3' OH is provided by the RNA primer. So prior to the synthesis of DNA a short fragment of RNA is synthesized that is later excised and filled with DNA molecules.
How does DNA fingerprinting relate to Poly Chain Reaction?
DNA fingerprinting uses variants in DNA sequences to create a unique profile for each individual, while the Polymerase Chain Reaction (PCR) is a technique used to amplify specific DNA sequences. PCR is commonly used in DNA fingerprinting to amplify regions of interest in the DNA sample before further analysis. This amplification step allows for better detection and characterization of DNA variations used in DNA fingerprinting.
What are the uses of DNA cloning in Forensic Science?
DNA cloning in forensic science is used to amplify and analyze DNA samples taken from crime scenes. This technique allows scientists to create copies of DNA fragments for further analysis, such as DNA profiling and identification of suspects. DNA cloning also helps in establishing genetic relationships and can be used to link suspects to crime scenes with high accuracy.
What is used to create a large sample of DNA for testing for a small sample of DNA?
A technique called polymerase chain reaction (PCR) is used to create a large sample of DNA from a small sample. PCR amplifies specific regions of DNA by making millions of copies, allowing for further analysis and testing on the amplified DNA.
A scientist wants to begin making a DNA fingerprint but she has only a very small DNA sample what should her next step be?
do a polymeras chain reaction (PCR). apex
Why was polymerase chain reaction developed?
makes more copies of a sample of DNA. apex
How does polymere chain reaction relate to DNA fingerprinting?
Polymerase chain reaction (PCR) is a technique used to amplify specific regions of DNA, making it easier to analyze. In DNA fingerprinting, PCR is often used to amplify certain regions of an individual's DNA to create a unique genetic profile that can be compared to others. PCR is a critical step in the DNA fingerprinting process as it allows for the identification of specific genetic markers that are used for comparison.
Process used to amplify small DNA samples?
Polymerase chain reaction (PCR) is a commonly used method to amplify small DNA samples. In PCR, the DNA sample is heated to separate the double-stranded DNA into single strands, then specific primers are added to flank the target DNA sequence. DNA polymerase then synthesizes new DNA strands complementary to the target sequence, resulting in exponential amplification of the DNA fragment.
What does polymerase chain reaction enable scientist to make?
Polymerase chain reaction (PCR) enables scientists to make millions of copies of a specific DNA sequence in a short amount of time. This technique is commonly used in research, forensics, and medical diagnostics to amplify DNA for analysis.
Is polymerase chain reaction used to amplify DNA from a fossil a fetal cell or a virus?
Yes, polymerase chain reaction (PCR) can be used to amplify DNA from a fossil, fetal cell, or virus. PCR is a powerful technique that can amplify specific DNA sequences, even from samples with low amounts of DNA, allowing for further analysis and research.
Is DNA Cloning used following procedures is used to amplify DNA in vitro?
polymerase chain reaction (PCR)
What does the PCR technique do?
The PCR (polymerase chain reaction) technique is used to amplify a specific DNA sequence in a sample. By utilizing a cycle of heating and cooling, PCR replicates the targeted DNA region exponentially, generating millions of copies for further analysis in applications such as genetic testing, forensics, and disease diagnosis.
What is cean technique what dose this involve when should this be used?
Clean techniques is the laboratory practices that is employed to reduce the risk of contamination and it should be used in forensic DNA laboratory so as prevent the transfer of the DNA from the analyst to the sample, environment to the sample, and cross-contamination between the samples.
