Genetic Variation Testing On Lynch Syndrome Lynch Syndrome is an hereditary nonpolyposis colorectal cancer which is a disorder that increases the risk of many types of cancer. Researcher says that people who have lynch syndrome are more likely to develop colorectal cancer than anybody. The genetic test for lynch syndrome is MLH1. MLH1 is Mutl homolo g1, Colon cancer, nonpolyposis type 2. Lynch syndrome also have an risk of cancer of the stomach, small intestine, liver, gallbladder…

Organisms across various environments develop and displays complex behaviours. Terrestrial animals, such as lions, displays evident social behaviours through the development of societies called prides (Abell et al., 2013). Similarly, fish have developed numerous social, reproductive, and predatory behaviours that allow them to adapt to various conditions. For example, observing reproductive behaviours of hermaphroditic reef fishes found that reproduction was species dependant, though there were…

infertility in a women. When the problem have to be with ovulation the treatment may include taking drugs, like Clomiphene to stimulate the ovaries. Sometimes technologies can be the solution to infertility like Insemination, In vitro Fertilization and gamete intrafallopian transfer, but the most common are Insemination and In vitro Fertilization. An embryo transfer can also be done in some cases when the sperm of a men have low quality. Some couples experience depression, stress, anxiety, low…

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) make up the nucleic acid in cells and is responsible for the differences in many of our traits. DNA is the substance in which our genetic material is carried on from one generation to the next. Nucleotides join together through phosphodiester linkages between the 5 ' and 3 ' carbon atoms to form nucleic acids. “Nucleotides are composed of a five-membered sugar group with a purine or pyrimidine nitrogen base group attached to its 1 ' carbon…

movement of Maggots? Introduction The Experiment aims to analyze the behaviour of the maggots. In this case, behaviour is defined as the way organisms respond to their environment. In the experiment, the orientation of the movement of organisms and gametes in response to external factors of the maggots will be studied using temperature as the external factor. Maggots are organisms that react by instinct and a series of varied reflex reactions are adapted. These inherited actions are very…

Embryos were originally a sign of great joy to come to a mother and father but this view has changed drastically over the years. Most of the time they are still looked upon as little bundles of joy, but sometimes they are perceived as a mistake or a reason for making rash decisions. They often bring couples many troubles costing their relationship and ending in a breakup or divorce. Few couples that are not able to get pregnant look to other solutions including IVF for happiness, but this still…

Throughout the history there have been many different reason for surrogates to be involved in the process of having children. The laws vary from state to state about how the process of surrogacy works, and it is even banned in some locations of the United State (Spivack, 2012). Surrogacy is not a new process in the late twentieth century African American women were surrogate for their slave masters giving birth to children to become property of the masters (Spivack, 2012). As of the 1978, there…

from this DNA. Ancient DNA is used today to trace back lineages and compare them to existing relatives of these species. • What I learned: In this presentation, I learned how we can make extinct species unextinct through placing the ancient DNA in a gamete and then fertilizing the egg to create…

Cell division is a complex biological method in which a parent cell divides into two or more daughter cells, depending on whether or not that division is mitosis or meiosis. For simple one-cell organisms, like amoebas, archaea and protozoa, single cell division, mitosis, is akin to reproduction. For multicellular organisms, meiosis produces four haploid daughter cells by undertaking a single round of DNA replication, shadowed by two more cellular divisions. In all, the principal purpose of cell…

Gene Therapy What is gene therapy? Gene therapy is an experimental technique that uses genes to treat or prevent diseases or disorders. Using gene therapy you can replace the non-functioning genes with good functioning genes. Although gene therapy is safe there are however side effects afterword which makes it risky. Before we go into depth about gene therapy here is some basic knowledge. So to put it in a simple way all we are doing is replacing a bad gene with a good gene. A bad gene is in…
