Baby DNA test: Who is the father? Part II

A baby DNA test is one means of establishing with certainty who the daddy of the unborn child is. One can of course choose to wait till after the child is born although it is important to know that this is not necessary as a paternity test can be conclusively carried out while the mother is still pregnant. How is the Baby DNA testing done? There are two main methods through which the unborn baby’s DNA can be sampled. Amniocentesis: this is carried out anywhere between week 14 and week 20 of the pregnancy and is normally done as a routine procedure to locate abnormalities in the chromosomes. [more...]

DNA test favors Va. man convicted of rape - Maryland Daily Record

DNA tests conducted under Virginia’s one-of-a-kind post-conviction DNA testing program indicate that a man who served seven years in prison for a 1979 rape didn’t commit the crime, and he wants Virginia’s high court to declare him innocent. Calvin Wayne Cunningham would be the eighth man exonerated by decades-old biological evidence and the third since Virginia began its massive project to clear those who may have been wrongly convicted in the 1970s and 1980s from biological evidence saved before DNA testing was available. Cunningham, 57, was convicted in 1981 of raping the [more...]

306 - The Genetic Map of Europe | Strange Maps | Big Think

Which means that forensic scientists now can use DNA to predict the region of origin of otherwise unknown persons (provided they are of European heritage). These are among the conclusions to be drawn from a genetic map of Europe, produced by the Erasmus University Medical Center in Rotterdam (the Netherlands), published in Current Biology’s August 7 issue. In its Science section, the New York Times devotes an article to the study, and reproduces the genetic map. The discovery that autosomal (i.e. non-gender-related) aspects of DNA may be used to predict regional European provenance of [more...]

Engineering Mini project: DNA COMPUTERS

After seven days of intensive laboratory work, Adleman's test-tube contained the answer to the problem, subsequently visible as a series of dark bands on a DNA sequencing gel. On the face of it, it might hardly seem worth the bother, especially as Adleman already knew the answer before he started the experiment. But this was much more than a curious laboratory stunt. During the initial 'linking-up' stage of the process, Adleman's test-tube computer effectively performed an astonishing 10^14 calculations. And it did so with the consumption of only a tiny amount of energy, and in a tiny [more...]

EveryDay Science » Blog Archive » New roles for new genes ...

Thanks to new technological advances in genomic sequencing , we know that much of the DNA genome is transcribed into RNA but only a small portion of this RNA (transcriptome ) contains sequences that encode for the synthesis of proteins. Thus, although long RNA fragments are non-coding transcriptome most mammals, their cellular functions are still unknown. Scientists have already described the role of small RNAs in gene regulation but we still know very little about the long fragments . The long noncoding RNAs are RNA fragments longer than 100 nucleotides. The authors of this paper have shown [more...]

HPV DNA Test for Cervical Cancer

According to Lab Tests Online, the HPV DNA test still requires a sample of cells from the cervix. It is NOT a blood test. I emphasize this point because most of the news I’ve seen either got it wrong or didn’t clarify the testing procedure. For most people, DNA tests still mean a blood test even though DNA can be extracted from other samples, such as the ubiquitous cheek swab. Currently, the HPV DNA test is used in combination with the traditional pap smear. However, recent studies have shown that HPV testing may be used alone and make it possible for women to prolong the time between [more...]

Pleiotropy: Some more junk DNA shown to have function

It shows a function for some "junk DNA" - DNA that does not serve any function for the developing organisms - namely in coding for micropeptides (very short proteins), which have now been shown to have a regulatory function in Drosophila. The first lines of the abstract readsA substantial proportion of eukaryotic transcripts are considered to be noncoding RNAs because they contain only short open reading frames (sORFs). Recent findings suggest, however, that some sORFs encode small bioactive peptides. Here, we show that peptides of 11 to 32 amino acids encoded by the polished rice (pri) sORF [more...]

How DNA is Used in Paternity Testing?

Recently, companies have begun selling DNA paternity tests over the counter at drug stores, which facilitates home testing. However, results are usually inadmissible in court due to the chance of surreptitious DNA collection or false identification of the tested individuals. The legality of testing another person’s DNA without their consent varies by state. If a paternity test is to be used in a court of law, chain of custody of the DNA sample must be verified. This means that every step of the paternity testing process and analysis is documented, from the collection of the DNA sample by an [more...]

False peaks in the profile created by imperfections in the analysis machine may also be mistaken for alleles. This is called "drop-in". This year, the Scientific Working Group on DNA Analysis Methods (SWGDAM), which issues guidance to US labs performing forensic DNA analysis, published new recommendations regarding the interpretation of forensic DNA. These include a suggestion that labs develop strict criteria for deciding what denotes the presence of an allele, and what amount of DNA constitutes the minimum for a profile to be constructed. Labs should also document and define any [more...]

Basics: Sequencing DNA, Part 1 « Genetic Inference

However, in certain respects Sanger Sequencing is still top-of-the-range. The 4-channel capillary approach lets you sequence DNA pretty fast, and each machine can often do hundreds of reactions at once. It was these machines that first sequenced the human genome. In addition, you can sequence relatively long sequences of DNA; up to 1000 nucleotides (after that, it gets difficult to tell the difference between molecules of different sizes). We have yet to make a machine that can sequence DNA fragments of this length faster than Sanger Sequencing (yet…). The modern Sanger Sequencing machines [more...]

Mutation Rate In Humans Gets Measured By Direct Sequencing

With better measurements of mutation rates, we could improve the calibration of the evolutionary clock, or test ways to reduce mutations, for example. Even with the latest DNA sequencing technology, the researchers had to design a special strategy to search for the vanishingly rare mutations. They used next-generation sequencing to establish the order of letters on the two Y chromosomes and then compared these to the Y chromosome reference sequence. Having identified 23 candidate SNPs – or single letter changes in the DNA – they amplified the regions containing these candidates and [more...]

Immigration Testing Is Easy Using DNA

Immigration testing has become simpler, faster and more accurate thanks to DNA testing. It is relatively easy to determine if the person applying for citizenship based on family ties is related by using a legal immigration test. It comes down to a simple question, can you prove that you are related to someone who is currently a citizen of that country? It is not uncommon that a parent would come to the United States and work for many years sending money home to take care of the children and family members. When that person becomes a citizen there are various programs and options to apply for [more...]

Learn The Basic Process Of DNA Paternity Testing

However, how does DNA testing work? The DNA Paternity Test is conducted by taking DNA sample of the supposed father and the child. The child has a combination of the mother and father’s DNA that is a known fact. Thus, the child’s genome will contain almost equal parts of the mother and the father. The proof of paternity is obtained by comparing the DNA sequences of both the child and the supposed father. If their DNA results match, it means that the supposed father is indeed the child’s biological father. If it doesn’t, then it sets things clear and gives peace of mind to both [more...]

Factors That Will Affect Sperm Health_26166

It should be noted that when the typical sperm analysis reveals normal count, morphology and motility this does not mean that sperm DNA fragmentation is not manifest. In other words, unless the SDIA test is specifically run, fragmentation issues will not be revealed. This type of case then may be labeled ‘idiopathic’ infertility. It is our opinion based on clinical experience that ideally, both the man and the women should be treated even if there is no apparent male factor evident. The reason for this is that stress has been shown to reduce sperm count. Going through the tortuous trial [more...]

My question is whether initially sheared genomic dna can be safely used for genome sequencing and assembly by 454 technology. By 'initially', I mean genomic DNA was sheared during extraction process. I attach gel image of my genomic dna samples (marker is lambda dna digested with EcoRI and HindIII). Although I know that dna fragmentation step is involved in standard genome sequencing by GS FLX titanium, I am concerned because I think it might be possible that shearing during extraction can affect randomness of standard fragmentation step and so on. Thanks in [more...]
