single cells (Unicellular organism). Presently, millions of years later, most plants, animals, fungi, and algae are composed of multiple cells that work collaboratively as a single being. Despite the various methods these organisms achieved multicellularity, their conglomeration of cells operate cooperatively to consume energy, survive, and reproduce. But how did multicellularity evolve? Once or multiple times? How did a solo cell transition to associating and cooperating with other cells? The origins

Department of Molecular Biology. Now Dr. Gitai focuses on the cell biology of bacteria and how their cells are able to self-organize across spatial scales. In the seminar that Dr. Gitai gave, he presented several questions that he asked himself, and his research team, while investigating why bacteria have certain shapes. His questions seemed very simple, but had no clear answers yet. He strategically began the seminar by asking how cells make big structures from small parts, and using analogies such

Many physiological processes in the cells require the participation of both intra- and extra-mitochondrial enzyme reactions. A link between mitochondria and cytosol is provided by a group of proteins known as the mitochondrial carriers (MCs) family (Arco & Satrustegui, 2005; F. Palmieri, 2004). MCs comprise a family of about 40-50 proteins, depending on the organism, and provide the main communication between mitochondrial matrix and extra-mitochondrial spaces by transporting a wide range of metabolites

I included 8 organelles that are found in the cell. One of these organelles is the nucleus. The nucleus is a large membrane-enclosed structure that contains genetic material in the form of DNA and controls many of the cell’s activities. The job of the nucleus is to protect the DNA and the RNA from anything outside the nucleus. Another organelle is the ribosome. Ribosomes are small particle of RNA and protein found throughout the cytoplasm in all cells. The ribosome is responsible for making protein

Technological advancements over the last hundred years have allowed health care systems around the world to better diagnose, manage and treat illness than was ever thought possible. One crucial machine that has improved patient diagnosis and outcome on soft body tissue injuries or disease is magnetic resonance imaging (MRI) (Al-Harbi 2016, 1-2). In 2003, scientists Paul Lauterbur and Peter Mansfield were awarded the Nobel Prize in Medicine for inventing magnetic resonance imaging (Collins 2016, 259)

sizes and instruction from the nation's best professors, I know it’s possible to easily interact with the professors that will help me mold myself into knowledgeable student I want to be In the College of Literature, Science, and the Arts is where the Cell and Molecular Biology and Biomedical Engineering Major is taught. This major fully encompasses all the necessary information to help college students succeed in the fields of biology and biomedical

many cells do replace themselves over time, but the wholesale brand new body thing is really more one of those myths people keep repeating and no one knows for sure where it started. But before we get into why it’s not really accurate, let’s do a quick anatomy review. Your cells are your body’s most basic building materials, right?. You’ve got trillions of them in about 200 different flavors, and each type is specialized for a different

Medicine and Genetic Research According to Kenneth Pakenham, Jo McEntire, and Jessica Williams (2013), in “Making Connections” Gene therapy and genetic tests are long experiment by scientists to find out specific genes are related to fatal diseases and birth defects. Many severe diseases depend on the gene type. When genes are known genetic tests for many genes will be available. Despite several challenges for gene therapy, genes treatment is possible identifying their defective genes tests. Pakenham

intrinsic developmental signals and extrinsic environmental cues (Inze and De Veylder, 2006). Many of these cyclin types have putative roles in cell cycle progression; however, some of them may function in other processes instead of being directly involved in cell cycle regulation. Different types of cyclins are involved in different stages of the cell cycle, providing specific regulations by targeting to different substrates. Generally, the majority of D-type cyclins are involved in the regulation

Researchers first thought the genes you receive from your parents are set in stone since they are made of a genetic code set in our DNA sequence;however, they are discovering that there is a second layer of structure that combines with DNA to decide whether or not a gene is active or not, called the epigenome. The epigenome consists of the DNA, histones, a protein DNA is wrapped around, and chemical tags. The epigenome alters the genetic code by directing signals. The signals come from the environment
