What is the VNTR area is and how is it used to profile DNA?
VNTR is variable number tandem repeats. These regions do not really mean anything to the genome but related individuals have similarities between their VNTR regions. In forensic analysis, VNTR analysis is used to place a suspect at a crime scene. IN paternity testing, VNTR information is gathered from both parents and matched to that of the child.
What are vntr?
Variable Number of Tandem Repeats (VNTRs) definition- sites where an enzyme can cut the DNA, and the location of these sites also varies from person to person.
The two main purposes for analyzing vntr dna from dna fingerprints are matching tissues and inheritance?
The two main purposes for analyzing VNTR from DNA fingerprints are matching tissues and inheritance - This is True
What kind of bacteria is VNTR widely used in?
tuberculosis, Leptospiosis, in Iran
Different persons have different DNA fingerprints because?
they have different numbers of the same VNTR.
Can lost tastebuds come back?
We pray so the person who is lost will come back to the person they love and we pray also for the person who is lost to come back safely
What is DNA fingerprint?
DNA fingerprinting (aka DNA profiling) is a scientific procedure used to determine identity or parentage using DNA. Variable Number Tandem Repeats (VNTR) are found in the nucleotides of a DNA strand. When there is a pattern of two or more nucleotides that is repeated, and the repeated patterns are directly adjacent to each other (CATCATCAT) this is a VNTR. These VNTR show up when used in gel electrophoresis, and this outcome can be used to compare DNA samples. If the pattern in the gel for a a blood sample matches the pattern in the gel for an adult, the blood most likely belongs to the adult.
What does venalicius mean in latin?
"Venis" means "You Come"."Venis" comes from the 4th Conjugation Verb, Venio, which means "To Come".Four Principle Parts of Venio:Veniō, Venīre, Vēnī, Ventum.The Present Tense Conjugation of Venio:Singular1st Person: Venio (I come)2nd Person: Venis (You come)3rd Person: Venit (He, She, It comes)Plural1st Person: Venimus (We come)2nd Person: Venitis (You [plural] come)3rd Person: Veniunt (They come)
Will your ashma come back?
It is possible that a person's asthma will not come back. Most times, when a person has asthma, it is a lifelong problem for them.
What are the pros and cons for DNA fingerprinting?
= Problems With DNA Fingerprinting = ---- Like nearly everything else in the scientific world, nothing about DNA fingerprinting is 100% assured. The term DNA fingerprint is, in one sense, a misnomer: it implies that, like a fingerprint, the VNTR pattern for a given person is utterly and completely unique to that person. Actually, all that a VNTR pattern can do is present a probability that the person in question is indeed the person to whom the VNTR pattern (of the child, the criminal evidence, or whatever else) belongs. Given, that probability might be 1 in 20 billion, which would indicate that the person can be reasonably matched with the DNA fingerprint; then again, that probability might only be 1 in 20, leaving a large amount of doubt regarding the specific identity of the VNTR pattern's owner. 1. Generating a High ProbabilityThe probability of a DNA fingerprint belonging to a specific person needs to be reasonably high--especially in criminal cases, where the association helps establish a suspect's guilt or innocence. Using certain rare VNTRs or combinations of VNTRs to create the VNTR pattern increases the probability that the two DNA samples do indeed match (as opposed to look alike, but not actually come from the same person) or correlate (in the case of parents and children).2. Problems with Determining Probability A. Population GeneticsVNTRs, because they are results of genetic inheritance, are not distributed evenly across all of human population. A given VNTR cannot, therefore, have a stable probability of occurrence; it will vary depending on an individual's genetic background. The difference in probabilities is particularly visible across racial lines. Some VNTRs that occur very frequently among Hispanics will occur very rarely among Caucasians or African-Americans. Currently, not enough is known about the VNTR frequency distributions among ethnic groups to determine accurate probabilities for individuals within those groups; the heterogeneous genetic composition of interracial individuals, who are growing in number, presents an entirely new set of questions. Further experimentation in this area, known as population genetics, has been surrounded with and hindered by controversy, because the idea of identifying people through genetic anomalies along racial lines comes alarmingly close to the eugenics and ethnic purification movements of the recent past, and, some argue, could provide a scientific basis for racial discrimination. B. Technical DifficultiesErrors in the hybridization and probing process must also be figured into the probability, and often the idea of error is simply not acceptable. Most people will agree that an innocent person should not be sent to jail, a guilty person allowed to walk free, or a biological mother denied her legal right to custody of her children, simply because a lab technician did not conduct an experiment accurately. When the DNA sample available is minuscule, this is an important consideration, because there is not much room for error, especially if the analysis of the DNA sample involves amplification of the sample (creating a much larger sample of genetically identical DNA from what little material is available), because if the wrong DNA is amplified (i.e. a skin cell from the lab technician) the consequences can be profoundly detrimental. Until recently, the standards for determining DNA fingerprinting matches, and for laboratory security and accuracy which would minimize error, were neither stringent nor universally codified, causing a great deal of public outcry.
