better understand the cell cycle and the different phases of mitosis, students were expected to observe cell division in an onion root. I hypothesized that we would observe more cells in interphase since most of a cell’s life is spent in interphase. In order to make observations, we used a light microscope to view two slides of an onion root—one had been previously prepared while the other slide was made by each individual student. Furthermore, we then counted how many cells were in which phase…

There was a mass production of “mitosis” and when that happens bad things like cancer can happen. So the cells fight of the mass production so they can defeat the cancer and things. This is when the mobs started to break out. In about 3 months I was getting threats because they wasted their money on something that is fake. Then about 5 months later mobs…

application builds on the discoveries made in the last funding cycle on effects of poultry dust on lung epithelial cells and monocytic cells, and lung inflammation in a mouse model. The data showed that poultry dust contains protease activity, induces robust inflammatory gene expression in lung epithelial and monocytic cells and activation of protease-activated receptors (PARs)-mediated cell signaling may be responsible for the elaboration of inflammatory gene expression. The data also showed…

The human genome is composed of millions of molecules of DNA perfectly packaged into 23 chromosomes. Each human is the result of a combination of the same four nucleotides, yet every single one is unique. Perhaps, this is due to the slight variation in each human’s DNA, or maybe the explanation lies in a person’s upbringing. The purpose of studying human development is to understand why people change by applying the scientific method to existing theories, which provide the basis for…

Deoxyribonucleic acid consists of a phosphate and deoxyribose backbone, and four different nitrogenous bases. These bases are adenine, guanine, cytosine, and thymine. Ribonucleic acid, the molecule formed in the transcription of DNA, is made up of phosphate, ribose, and adenine, guanine, cytosine, and uracil. The backbone of DNA consists of a phosphate bonded to a deoxyribose molecule. Deoxyribose is a sugar containing five carbons, and it is called deoxyribose as it is missing an oxygen atom on…

highly abundant in eukaryotes, prokaryotes and even small bacterial genomes. SSRs can be found anywhere in the genome both in coding and non-coding region and may be arise through an error in the process responsible for copying of the genome during cell division and they are unavoidable…

the myocardial damage that this disease causes. In the past, gene therapy was not a viable candidate for the treatment of heart failure because of the nature of myocardial cells. They rarely divide unless there is substantial tissue damage, and this meant that many older vectors for gene therapy could not target heart cells. However, recent advancements in gene transfer technology and gene therapy vectors have turned cardiovascular gene therapy into a scientific…

and his dog Blobby were green cells that lived in a human named Tyler. It was very strange being a cell. Although, it was almost the same world that humans lived in, just different. For example, instead of roads, they had bloodstreams, instead of humans and their pets, everyone was a cell, just in a different form. Roads still existed and they were still called ‘roads’, or at least by the cells. If you were a human, you’d call it a bloodstream. The small world the cells lived in was like a…

Introduction DNA makes up the genetic material for all organisms. However, not all organisms have distinct molecules working with DNA that come together to make up chromatin. Chromatin is only found in eukaryotic cells, the cellular makeup of multicellular organisms. The structure of chromatin is composed of DNA and histones, together making up nucleosomes, and other non-histone proteins that bind to the DNA. The backbone of DNA is negatively charged and histones have a positive charge…

Prokaryotes can be recognized as a single-celled organism that lack the extensive internal compartments. Unlike eukaryotes, the prokaryotes concentrated their genetic materials in a small portion of cell’s cytoplasm known as nucleoid. Almost entire prokaryotic genome is contained in a single circular DNA strand that is supercoiled. Some additional genes are located on an independent small, circular or linear plasmids which coding for extra properties likes antibiotic resistance (Brown, 2002).…
