Types of DNA Technology - 1361 Words

DNA Technology: Biotechnology 1) Selective breeding a. 2) Genetic engineering – humans tinker with organisms genes a. Cloning –take haploid cel and replace with a diploid nucleus (comes from organism whos traits you want to duplicate. b. Recombinant DNA – DNA from 2 or more sources. Done by Euk cells during Meiosis. Always from same molecule. 3) Biologists first started doing recombinant DNA from a prok cell and combined it with another prok cell because it was easier. 4) DNA from a euk cell and combine it with DNA from a prok cell Features of bacteria that make them useful subjects for recombinant DNA technicians: 1) Short generation time. Divide fast 2) Easy uptake of DNA from environment (transport from environment)†¦show more content†¦V) Endometrium begins to thicken due to the estrogen VI) Tons of mucus in cervix makes ovulation mucus VII) Switch from slow to fast pulse rate. VIII) Formation of the corpus luteum from old follicle cells Estrous cycle – 1) Doesn’t occur in human females 2) Usually the only point where female is interested in mating. Complete hypothalamic inhibition in females: 1) Effects anterior pituitary gland by turning off LH and FSH 2) Leads to corpus luteum to die 3) No more estrogen + Progesterone a. Leads to closing Endometrium is thickening when GnRH formation is slowing down. Endometrium is dying when GnRH ceases to exist Increase of FSH creates more estrogen Chronic villi secrete the hormone HCG which is used to determine if you are pregnant or not. It is only present when a woman is pregnant. Fertility Drugs: Usually made of synthetic FSH Makes a woman ovulate more than 1 egg during ovulation Decreasing Chances of Pregnancy (Contraceptives) Abstinence (HAHAHA) Outercourse – no intercourse Pharmaceuticals The mini Pill – No estrogen only progestin. Makes the endometrium inhospitable. The combo pill Some of estrogen + lots of Progestin Creates complete hypothalamic inhibition Surgical procedures In males: Vasectomy – cut vas deferens In Females: Tubal ligation Liquid silicon inserted in fallopian tubes Tubes cut/cauterized Other Methods of Birth control: i) Patch – Transdermal ii) Ring – Nuva ring inserted inShow MoreRelatedTechnology And The Medical Field Advances875 Words   |  4 Pages Technology has been advancing throughout history. People life has changed. Most of the people now have longer lifespan than before. As technology advances, the medical field advances accordingly. With these advances, people can survive from deadly disease. For example, chickenpox was deadly before a vaccine was found. With modern medicine, many diseases became curable. However, DNA mutations diseases where it survive and passed through our DNA to many generation can be difficult to cure and trackedRead MoreThe And Viruses And Their Biological Function Essay1527 Words   |  7 Pagesacquisition of spacers, crRNA biogenesis, and interference. The infection by undocumented DNA starts the acquisition of viral DNA. Upon the detection of the invasion of bacteriophages, bacteria defend themselves in a timely fashion by inserting bits of viral DNA, the protospacer, into their chromosome at the end of CRISPR locus. To maintain the structure of CRISPR array, bacteria initiate the replication of a repetitive DNA sequence, the repeat. Next, crRNA biogenesis takes place in two stages. First, theRead MoreOrigin : Bacterial And Archaeal Adaptive Mechansim Essay1640 Words   |  7 Pagesinterference (Wright, Nuà ±ez, Doudna, 2016). The infection by undocumented DNA starts the acquisition of viral DNA. Upon the detection of the invasion of bacteriophages, bacteria defend themselves in a timely fashion by inserting bits of viral DNA, the protospacer, into their chromosome at the end of CRISPR locus (Wright, Nuà ±ez, Doudna, 2016). To maintain the structure of CRISPR array, bacteria initiate the replication of a repetitive DNA sequence, the repeat (Barrangou et al., 2007). Next, crRNA biogenesisRead MoreThe Crime Scene Of A Virginia Man999 Words   |  4 PagesWhen dealing with other types of evidence such as hairs and fibers, tool marks, video footage, or even a weapon used at a crime scene; it can be challenging connecting the evidence to the suspect or even coming up with a suspect. These forms of evidence have been allowed in court in many cases and have also convicted many innocent people. Years later, their cases have been re-opened with new DNA evidence and have set the innocent free. According to the Innocence Project, Randolf Arledge was accusedRead MoreTechnology And The Field Of Criminal Justice Essay1321 Words   |  6 PagesFor over a century the world has been making advances with technology in all areas of life, and the field of criminal justice has not been an exception to this technological advances. These advances in technology has taken the criminal justice field a long way from riding a horse bareback to driving armored cars. Thes e advances along with many others have almost completely changed how things are handled in all aspects of the law. Technology is the persistent application of information in the designRead MoreOrigin And Development Of Crispr Cas9 System Essay1620 Words   |  7 Pagesinterference (Wright, Nuà ±ez, Doudna, 2016).

The developmental history of the CRISPR-Cas9 system has revealed that how basic biological research will drive the progress of biotechnologies and therapeutic methods. The story of this novel technique began in 1987 when Japanese researchers Nakata and his colleagues observed a series of 29nt DNA repeats interspaced by five 34ntRead MoreA Brief Look at DNA Profiling1366 Words   |  6 PagesDNA profiling has several advantages in helping solve crimes, however, there are still disadvantages to this technique. DNA profiling can be beneficial, as well as detrimental to the society we live in. DNA profiling has become the most widely used tool in the field of forensics because of the advantages it has to offer, although there are some drawbacks when it comes to utilizing this technique. DNA profiling has greatly enhanced law enforcement investigation by helping determine the suspect inRead MoreThe Use Of CRISPR Technology1183 Words   |  5 Pagesway to edit our DNA with the use of CRISPR technology. This technology allows scientists to change the DNA within our cells that could ultimately allow scientists to cure various genetic disease such as sick le cell anemia, Huntington’s disease and cystic fibrosis etc. The way this technology works is that the Cas9 protein seeks foreign DNA, and precisely cuts that DNA out and eventually degrades it. After the mutated DNA is removed from the double helix, the cells detect the broken DNA double helixRead MoreDna Editing System For A Type II Crispr System Mechanism1295 Words   |  6 PagesCRISPR/Cas9 DNA editing system is a prokaryotic immune system that becomes resistant to foreign genetics such as plasmids. CRISPR stands for Clustered Regularly-Interspaced Short Palindromic Repeats, which are prokaryotic DNA strands that have a short repetition base sequence. Cas9 is a nuclease enzyme that is used to cut into DNA strands that are associated with CRISPR type II. CRISPR/Cas9 system has several advantages when using this technology in the biological and biomedical sciences. It also
