Prokaryote

that is prescribed from a doctor to a patient to provide faster fighting in a bacterial infection (2). Bacteria can grow and reproduce fast, thus creating a challenge for your immune system to be able to fight them off. Bacteria are classified as prokaryotes and can survive in extreme conditions (3). Bacteria are more commonly know as “germs” (3). There are many advantages and disadvantages if our government decides to restrict the use of antibiotics. The use of antibiotics should be…

The importance of noncoding DNA sequences Since the completion of Human Genome Project in 2003, it was found that more than 98% of human genome is occupied by noncoding DNA sequences (Genome.gov, 2003), existing between genes and as introns within genes (Figure-1). In genomic, noncoding DNA regions are defined as the sequences of an organism’s DNA, which do not code for proteins. Although it has been known for decades that some of these sequences code for noncoding RNAs that…

Bacteria, virus, and prions all play a part in our life, good and bad. Bacteria are forms of life that are considered living. That’s the difference between virus and prions, who lack the ability to reproduce once they are isolated. The reason behind that is because viruses and prions need a host to reproduce. Bacteria are single celled microbes. The cell is simpler than other organisms because there is no nucleus or membrane bound organelle. Bacteria’s genetic information is contained in a…

Both cilia and flagella found protruding from the cell body on the surface of eukaryotic cells are made of many microtubular bundles. Cilia are hair-like structures that protrude from the cells surface in eukaryotic cells they are covered by a plasma membrane. They are formed from a stable bundle of microtubules; these grow from an area in the cytoplasm called the basal body. Microtubules are made of a protein called tubulin, alpha has a slightly negative charge and beta has a slightly positive…

Relationship between cells Cells contain organelles these are the basis of a cell it contains many organelles and is basically the same a human these cells are the basic blocks of life cells are microscopic and what makes up tissues. Tissues are visible to the naked eye and are what creates us there are four main types of tissue connective epithelial nervous and muscle. Tissue makes up organs these are the what run us humans and every other living thing these keep them alive and have many…

stage numerous reactions can occur in the cell’s cytoplasm, and glycolysis will then take the molecule and break it down. The stage of cellular respiration is Krebs cycle, this cycle happens in mitochondria in eukaryotes and also in cytoplasm in prokaryotes. There are many steps to this cycle however enzymes, and catalysts have a big role in individual reactions. The pyruvic acid in created by reactions in glycolysis go through multiple reactions and create carbon dioxide and other products. The…

Endosymbiotic theory describes how large host cells and engulfed bacteria could easily become reliant on each other for survival. Phycol (2001, p.951) states that the theory of endosymbiosis describes the establishment of plastids from cyanobacterial-like prokaryotes living within eukaryotic host cells. After thousands of years of evolution mitochondria and chloroplast have become more specialized and today they cannot live outside a host cell. Figure 2 below shows how…

This paper will refer to the domain of Archaea. The archaea are single-celled prokaryotes that were classified in the bacteria domain naming them the Archaeabacteria. Until just recently the scientific community decided that these special creatures belonged in their very own domain. The archaea resembled the eukaryotes more than the bacteria even though they were still a prokaryotic organism. So these micro-organisms had to be moved into its own domain. These organisms are what many…

Siqi Li May 2015 What topics will students address during the beginning of the school year in Buffalo? During the beginning of the school year in Buffalo, students will study two parts of Living Environment in 7 weeks. The main topic is about the introduction to the course includes the cell which is the foundation of the study of all living things. The key idea 1 in curriculum, living things are both similar and different from each other from nonliving things. The enduring understanding is…

and evolved into many very complex species. Evolution is said to have started on a prehistoric earth after it had formed over 4.6 billion years ago. It took about a billion years after Earth was formed just for the first very simple single cell prokaryotes to appear, and it would take 3 billion more years before the most simple animals would appear. So this theory doesn’t show life coming into existence overnight, like a creationist theory tries…
