Agatha Christie’s And Them There Was None is a murder mystery based on the original poem “Ten Little Soldier Boys” where ten individuals are invited on an island and are mysteriously being murdered by an unknown character. Throughout the novel, the structure is shown in…

Schneider-2 cells S2 cell maintenance S2 cells are derived due to the spontaneous immortalization of tissue broken down from late-stage Oregon-R embryos (Schneider, 1972 ). Cells are acquired as frozen stock from Drosophila Genomics Resource Centre (DGRC) and revived as per instructions on their website….

Mammalian cell culture refers to cells that are isolated from the body of a mammal and are placed into an artificial medium (in vitro) which promotes their growth. Special skills and methods of preservation are needed to maintain the viability, structure and function of the…

As lateral root primordia development occurs deep within primary roots, remodeling of overlying tissue cell walls is required to accommodate growing primordia during LRE. Previous research involving cell wall remodeling (CWR) induced by the auxin signaling pathway, and IDA-peptide signaling, identified several enzymes responsible for…

Somatic Cell Nuclear Transfer Somatic Cell Nuclear Transfer (SCNT) is a cloning process that involves removing the nucleus of an egg cell and inserting the nucleus from a somatic cell. The nucleus is then “reprogrammed” by the egg cell and contains the DNA of the…

Artificial sweeteners, or non-nutritive sweeteners as they are sometimes referred to, have been controversial since they were first introduced to the market in the 1950s, and scientific research shows they are associated with many dangerous side effects. Introduced to satisfy consumers’ sweet tooth, these artificial…

Candidate miRNA Target Prediction In silico target prediction of candidate miRNAs were conducted through TargetScanFly6 (Kheradpour et al., 2007), with a version last updated in 2015. The top three non-hypothetical proteins listed are considered top hits; however, if a gene within sight is known to…

Meiosis in angiosperms (flowering plants) occurs within the floral organs of the plant and is defined by two major features: recombination of the pre-meiotic chromosomes and the reduction of ploidy in half. The ploidy is reduced in half because a single round of DNA replication…

Learning the safety procedures is always the first and most important thing to do before entering a lab of any kind. Learning the safest methods and using the best practice methods is especially important in a cell culture laboratory. While handling and culturing cells, it…

Heat shock proteins (HSPs) are highly conserved family known to be master regulator of thermal stress. Circulating leukocytes can be used as an effective model to understand response revealed by thermally stressed animals in tropical climate. Present investigation was aimed to evaluate comparative cellular tolerance…

INTRODUCTION: Lower urinary tract symptoms in perimenopausal female are mainly due to urethral stenosis. Chronic urinary retention usually presents with impaired detrusor contractility, bladder outflow obstruction or even with a combination of both problems. In these women treatment modalities basically rely on urethral dilatation and…

The Discovery Of Hela Cells has drastically improved the science industry within only a few years after they were taken from Henrietta’s tumor and grown in culture. After Jonas Salk used HeLa to test the polio vaccine he created, the mass production of HeLa cells…

Abstract Neutral red dye transports through a membrane of yeast cells using active transport.. We decided that changing glucose concentration could overcome inhibition of active transport channels in S. cerevisiae and lead to an increase of ATP made available to the cell; therefore an increase…

Plant and Animal Biology Abstract The system allows the exchange of O2 and carbon dioxide between the cells and also the air, so sanctioning the consumption of O2 into the body for aerobic respiration and also the unleash of carbon dioxide for regulating of bodily…

Total cell lysate Tetrahymena cell from 5 ml culture of the density 2.5 x 105cells/ ml were pelleted at 1700 xg, cell pellet was resuspended in 100 μl of 10 mM Tris-HCl, pH = 7.4. To lysate cells, an equal volume of hot 2.5-fold concentrated…
