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.
Why was polymerase chain reaction developed?
makes more copies of a sample of DNA. apex
Is DNA Cloning used following procedures is used to amplify DNA in vitro?
polymerase chain reaction (PCR)
What is clean 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.
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.
What is used to create a large sample of DNA for testing for a small sample of DNA?
PCR
What process is used to amplify small DNA samples?
Poly merase chain reaction
How can DNA solve crimes?
It can be used to identify the criminals easily if the criminal's hair sample or blood sample is collected and comparing it with the DNA of the suspects
What was the impact of DNA fingerprint?
DNA finger printing or DNA typing is very powerful technique that uses DNA markers. Forensic people benefit from this technique as it can be used to identify a paternity and also DNA samples from the crime scene can be matched with that of a suspect. DNA polymorphism is the main aspect that is focused on in this technique.
What is the purpose of the polymerase chain reaction (PCR)?
Polymerase Chain Reaction (PCR) testing is a technique to amplify a single or few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence. This allows for easier identification of particular DNA segments and can be used to assist in the diagnosis of certain diseases.
How do you find whether given sample is DNA or RNA?
A spectrophotometer can be used to know if a sample is DNA or RNA. DNA has an absorbance maximaat 260nm, whereas RNA has an absorbance maxima at 280nm. By looking at which one of these two wavelengths the sample is more excited, one can determine if the sample is DNA or RNA.
The technique used to analyze DNA directly results in?
separating DNA fragments on the basis of size
Can a scientist tell from DNA result alone what type of DNA sample were used in the test i.e. is it from blood or semen sample?
Yes, because each DNA is unique and and the scientist can just match the DNA up with andother DNA.
