B cell

named due the mistaken belief that germ cells arise from this surface layer. Instead germ cells are more likely to arise from the gonadal tissue itself (2). Spindle shaped cells called the ovarian stroma constitutes the major cell type ubiquitous throughout the body of the ovary. In the periphery,…

transferring yeast cells onto YPD and SD plates over a period of 24-72 hours in a thirty degrees Celsius incubator, in return will grow yeast. Introduction Yeast can reproduce both asexually and sexually, which makes it very easy to grow in the laboratory, as it is very small in size. Mutant yeast can be easily isolated considering yeast consists of a single cell and can be grown as a haploid or diploid. Diploid cells are formed by the combination of MATa and MAT alpha cells. However, under…

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…

Stem cell transplantation has been used, yet the long-term outcome is unknown. Although this is not considered genetic engineering it appears to be the closest mechanism used for this syndrome. Ideally, because this is a hereditary disease, laboratory research…

It was an honor to have Dr. Jeremy Boss deliver an informative presentation regarding his current research. Dr. Boss presentation was entitled; “Epigenetic regulation of adaptive immune responses”. Dr. Boss’ research is conducted at the illustrious Emory University of Medicine. At his institution, Dr. Boss research efforts are focused around microbiology and immunology. His efforts are to find out how to stop the adaptive immunity diseases. During his presentation, Dr. Boss stated that the…

unit of life is the cell. All living things are composed of cells. Cells may only from through a process of division and replication of previously existing cells. Cells are microscopic; however their structure is complex. All types of cells possess a plasma membrane which separates its contents from its surroundings. . There are two types of cells: prokaryotic and eukaryotic. a. Prokaryotic cells are simpler than eukaryotic cells. Within prokaryotic cells are bacteria cells and archaea. All…

identify concepts on cells and to learn more about the functions and reproduction of cells within living organisms. Lab Summary: While doing this activity we experimented with bacterial growth and I was able to witness growth in its replication. Through the process of mitosis, I was able to view cellular reproduction. Lab Answers A. Bacterial growth observation. The population doubling time is estimated to be 20 minute. B. Cellular reproduction : The three types of cell separation are…

within a cell, they can be expressed in response to external stimuli. This external stimuli can be sub lethal heat shock (SLHS) hence the name heat shock proteins (Baneyx, F. 2008), this stimulus causes more of the proteins to be produced (Pugsley, A. 1989). In addition to being expressed due to SLHS they can also be expressed in response to amino acid analogs, heavy metals…

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.…

Various prominent cells of the motive are articulated, particularly the interval of the major 3rd, which is passed around in various registers. At 2:19 a cell of the motive is used as an accompaniment figure in the L.H. At 3:35 the fuller melody returns in several tessituras. At 3:56 a small apotheosis of the theme occurs. At 6:23 a key…
