Resident populations that eat salmon and migrate in the waters near Washington state are more closely related genetically. Transient populations that migrate greater distances in the open seas and primarily eat seals and sea lions have more genetic differences between each other & the resident pod whales. These pods are known as ecotypes. DNA evidence indicates that these whales may be evolving into different species. ]]> 2022-01-27 02:58:10 UTC https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2014938346 All of Us--Helping to Achieve Precision Medicine ginawoodard https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2015018337 The goal of the All of Us program is to improve health care and build a program of precision medicine through DNA research. All of Us is building a diverse genetic database of over a million individuals who voluntarily donate their DNA so that researchers can identify genetic conditions and common genetic trends among cultural, racial and gender groups. The results of the program will inform researchers and physicians on how to better: a) identify risk factors for certain diseases, b) understand which treatments work best for people of different backgrounds, and c) focus on technologies that can help prevent disease and help us live healthier lives.

In the experiment they inserted GFP into the cat's DNA strand, GFP is a gene found in jellyfish that make them have a fluorescent glow just like the one in the picture. Years prior scientists found out this was a good marker gene so if they inserted it with another gene they could see if it combined. The experiment inserted GFP as well as a gene that prevents AIDS in cats into the unfertilized eggs. The kittens that cam from those trials glowed green, they also had the anti FIV gene through testing. The cats were also able to pass down the gene. Gene editing lets us test the possibility of healthcare, and what we can fix even before birth.]]> 2022-01-30 23:40:59 UTC https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2020388076 Gene and organ cloning aurea2 https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2020687097 Scientists have been working on ways to bring back extinct species. Through the process, they discovered how to clone animals. The process includes getting a DNA sample from the animal they wish to copy and inserting the DNA into an empty egg cell. The egg cell is then inserted into an adult female animal, which gives birth to an offspring with the same genetic material as the animal the DNA was taken from. This process has been used to clone many animals, like a cow, and they hope to advance this technique to save endangered animals or even bring back extinct species.]]> 2022-01-31 06:40:28 UTC https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2020687097 Analysing a DNA profile 15850342 https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2455267901 Forensic scientists can use DNA profiles to identify criminals or determine parentage. A DNA profile is like a genetic fingerprint. Every person has a unique DNA profile making it very useful for identifying people involved in a crime. It's most useful when placed alongside other evidence, such as fingerprints, footprints, crime scene examination, and eyewitness accounts. There are databanks for example, in New Zealand, there's a databank of DNA profiles. It contains over 70,000 DNA profiles of convicted offenders and some volunteers. This national databank collection can be matched against DNA profiles collected from unsolved crimes.

Medical and forensic fields seem to be were DNA testing is mainly used. Whether the testing is for paternity tests, disease screening, or law enforcement investigations, they can come with bad things. For some families, it would benefit them to know who their children's father is, however, for someone who has raised a child as their own, it might be difficult to find out it in fact, was not their child. Knowing that you are really likely to have a disease that can be prevented and would completely change your lifestyle. Not everyone is able to make these life changing shifts, which is why some would opt-out of a DNA test that could show said diseases. Although DNA testing has done many wonderful things for criminal cases such as show the true culprit of a crime, it is really easy to tangle and mess with the DNA used for these tests, therefore giving incorrect results.]]> 2023-01-24 19:49:00 UTC https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2455271630 Gabriel Rocha https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2455275518 You can compare animals from the same species or different species and Molecular clocks are used to determine how closely two species are related by calculating the number of differences between the species’ DNA sequences or amino acid sequences.

People use this to gain legal rights to have child custody, or child support. One way to take these paternity tests is by taking blood. The father and the child have to give some blood to the doctor to analyze them in a lab. Another way to do this is by doing cheek swabs. The doctor swabs the inside of the father and the child's cheek to analyze the saliva in a lab, inside the cheek are cheek cells, or buccal cells. Some paternity tests can happen while a woman is pregnant. There are three tests a woman can take while being pregnant: Non Invasive prenatal paternity test (NIPP), Chorionic villus sampling (CVS) and Amniocentesis. The test results come out into the lab, or on the hospital's website, results usually take a few days. There are also home paternity test kits that people may use, even though they are a bit costly (60$-200&$).]]> 2023-01-24 19:52:21 UTC https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2455275753 DNA is 1583949 https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2455276056 During morning hours, ATV's are sent out onto the beaches to check for sea turtle tracks from mothers who made a nest to lay their eggs. Some tracks are different than other because the species of mother turtles are different. This is due to their DNA coding their appearance to be different. Once they lay their eggs, it takes about 60 days for the baby to form, and once they hatch, their DNA codes them to walk towards the brightest horizon. This is usually the ocean. However, light pollution near beaches causes the baby turtles to become confused and some of them do not make it towards the ocean.]]> 2023-01-24 19:52:35 UTC https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2455276056 DNA Cloning 1584490 https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2455276752 Over the last 50 years, scientists have conducted cloning experiments in a wide range of animals using a variety of techniques. It was not until 1996, however, that researchers succeeded in cloning the first mammal from a mature (somatic) cell taken from an adult animal. After 276 attempts, Scottish researchers finally produced Dolly, the lamb from the udder cell of a 6-year-old sheep. In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed.]]> 2023-01-24 19:53:11 UTC https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2455276752 DNA & Paternity https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2455277070 Paternity tests require the DNA of the child and the possible father.

This dating back to there survival over 1 million years ago and revealing the genetic changes for there survival during the ice ages. Scientist analyzed the molars of two mammoth fossils found in Siberia. In the DNA they found that these two mammoths were already adapting to the conditions of the ice age when they passed. This then changed the entire view on mammoth history and added new chapters to there past. This discovery connected some of the puzzle pieces of another hybrid woolly mammoth. Without the DNA of these two mammoths we might have never saw the change of the mammoth species. ]]> 2023-01-24 22:26:47 UTC https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2455419835 Pros & Cons of genetic testing 1584736 https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2456712978 The DNA pros of genetic testing can help you know more about your health or any diseases you may have, it is less expensive than genetic testing with a healthcare provider. Your results are anonymous and are available quickly and it doesn't require approval from a health company or provider. The DNA cons the testing can give you are unexpected information or having misunderstood information from the test. The tests aren’t always correct and sometimes they might need a look from a professional and they only give you partial information about your health.

Today the best known test is called the ABO system. It works by taking a blood sample, and looking at the antigens in the blood. This is so that they can find if the father's blood type is similar to the child's. For example a man that has type AB blood, cannot be the father of a child that has type O blood. This is because he would pass on the A allele or the b allele or sometimes both. At the beginning paternity testing wasn't very trusted and accepted, by then it was only 40% effective. Now it's about 100% effective. Not only has the effectiveness been improved over time, but it has also opened various methods of paternity testing. Now paternity testing has become more precise and is much more available.]]> 2023-01-26 02:48:50 UTC https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2457035710 The role of DNA testing in the justice system https://padlet.com/ginawoodard/pf3krlay9fjh5ltj/wish/2460550325 The role of DNA testing in the justice system is to find out who the criminal is at a crime by the DNA they left behind. DNA samples are fragile and can degrade over time, which can lead to errors during the sequencing process, especially if the amount of sample material is small. Inconsistent methods for interpreting DNA sequencing data, especially that of DNA mixtures, leads to inconsistent verdicts on the identities of DNA donors.
