T cell

Trisomy X Trisomy x syndrome, also known as triple x and 47xxx, is characterized by the presence of an extra x chromosome in each cell of a female. Three x chromosomes are present, rather than a normal pair in the nuclei of body cells. The first published report of a women with triple x syndrome was Patricia A. Jacobs at Western General Hospital in Edinburg, Scotland, in 1959. The condition occurs in about 1 in 1,000 newborn girls. Five to 10 girls with triple x syndrome are born in the united…

Introduction Background While the clinical validity of genetic tests is growing, there emerges a concern that the disclosure of individuals’ genetic test results could lead to discrimination by health insurers and employers (Hudson et al., 2008). Federal legislation addressed the protection of individuals’ genetic information by passing the Genetic Information Nondiscrimination Act (GINA) in May 2008. The law prohibits health insurers and employers from using an individual’s genetic…

After looking at the results, there seemed to be a match between DNA found at the crime scene and DNA from one of the suspects. DNA from the crime scene with enzyme one matched closely with DNA from suspect two that was with enzyme one. Along with that match, the DNA from the crime scene with enzyme two was matched closely with DNA from suspect two with enzyme two. Because there were close matches to the DNA found at the crime scene, does not necessarily mean that the suspect is guilty. There…

not surrounded by a membrane but are located in an area of the cell called the centrosome. The centriole has its appearance and structure the way it is because its arrangements must be a circular and the triplet fibers that it’s made out of will eventually create a shape that is similar to a barrel when it it is arranged. One of their main function is to contribute/help with processes that involve cellular activities. One example of cell division where centriole plays a role in mitosis where…

restored. Did you know there are approximately 100,000-150,000 pieces of hair growing out of your scalp. Scientists have discovered 2 things why hair is so thick on your head. 1 thickness is made from Keratin the protein which is dead cells lifted above and new cells created below. Secondly, the structure which operate hair growth are hair follicles-This is how your hair grows constantly beginning for when you were born till you die.…

and proteins. These macromolecules are essential to the structure and function of a cell. Despite each serving different…

Cloning is a cell, cell product, or organism that is genetically identical to the unit or individual it is derived from. During the process of cloning, a piece of DNA is cut from its source with a restriction enzyme. Then, the DNA is put into a vector ( a DNA molecule used to transport genetic material into another cell). The vector is introduced to a host cell by the process called transformation, then the host cell copies the vector DNA with the original DNA; creating copies of the inserted…

Geiger Counters and Ghost Hunters: Is it Cutting Edge or Just Pseudoscience? There is a need for real scientific methodology in paranormal research if it is to be taken seriously by the scientific community in general. There are two main competing arguments going on in the realm of paranormal research and investigation. One side says there is break throughs happening in the field and they are using high tech equipment and scientific figures to conduct their investigations and they are very…

There are two types of gene therapy treatment: Somatic cell gene therapy and germline therapy. Somatic cell gene therapy includes gaining blood cells from a person with a genetic disease and then inject a normal gene into the defective cell. This type of gene therapy cannot be passed down generations (from parent to child) because it does not affect the egg and sperm cells. Somatic cell gene therapy needs to be done a few times to be permanent in a patient. The other…

The fruit flies does deal with dominant vs. recessive for the wing traits. Complete dominance occurs when the dominant allele complete cover (hide) the recessive allele. This occurs to the wing traits in the fruit flies. Normal wings are dominant over vestigial wing and base on the data, the female that carries the vestigial wing did not create any F1 generation of vestigial traits. This occurs because the male has normal wing so when the two parent meet; the dominant normal wing in the male…
