that have DNA in a membrane-bound nucleus.(En.wikipedia.org, 2017) A eukaryotic cell is a large, more complex cell compared to a prokaryote. Inside a eukaryote, consists of many different organelles, all with vital roles to play…

The next topic a student should be schooled in is cells and cellular biology. While cells are the building blocks of all living organism, scientists have confirmed that there are actually different types of cells depending on the organism. The two main classes of organisms are the prokaryotes and the eukaryotes. The prokaryotic is the simpler of the two and are the one-celled organisms such as bacteria and archaea. The interior of a prokaryotic cell consists of a main nucleoid, which contains…

specialized functions. There are two main categories with most organisms and their cells; prokaryotes and eukaryotes. The distinctive difference between prokaryotes and eukaryotes is that eukaryotic cells contain membrane-bound organelles, such as the nucleus, while as prokaryotic cells do not. Plant cells are eukaryotic, plant cells have a nuclei and membrane bound organelles. The main organelles…

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…

Genome is the genetic complement of an individual. The genome includes both the genes and the non-coding sequences of DNA/RNA. The term genome can be applied specifically to mean that stored on a complement set of nuclear DNA but can also be applied to that stored within organelles that contain their own DNA as with the mitochondrial genome or the chloroplast genome. All prokaryotes and eukaryotes genome contain significant portion of repetitive DNA, there are two categories of repetitive DNA in…

Though numerous advances have been made, heart failure remains one of the leading causes of death in the modern world (Kalyanasundaram & Periasamy, 2008). This struggle to defeat heart failure has made researchers desperate to find a solution that can prolong people’s lives and reverse 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…

Progeria, the name of a daunting rare and fatal disease can also be referred to more specifically as Hutchinson-Gilford Progeria Syndrome, or the acronym of this term, HGPS (Chara, 2002; Guang-Hui et al., 2011; Gruenbaum, 2009). Progeria originates from the Greek word “geras” which means “old age” (Gulli & Mallory, 2002). The prefix “pro-” means to advance forward so the combination of these two terms create the meaning “prematurely old” (Wynbrandt & Ludman, 2000). Dr. Hastings Gilford is…

Organelle Failure Nucleus: The nucleus of a cell is, without doubt, one of the most important parts of the cell. The nucleus instructs every single part of the cell what to do, and what the different organelles need to do. The nucleus includes chromatin (protein and DNA). It also contains Nucleolus (nucleoli is plural). These nucleoli are responsible for ribosome production. If the nucleus were to suddenly malfunction, this would mean that the cell would have no directions, and nothing to…

definition of Eukaryotes is that they are any organism whose cells contain a nucleus and other membrane enclosed organelles. Taxonomically, Eukaryotes belong to the taxon Eukarya. The three types of eukaryotic microbes are fungi, protozoa, and algae. Because the three types of eukaryotic microbes are all composed of eukaryotic cells, they have basic similarities in cellular structure, including the presence of a nucleus. However, these types of microbes do differ in many significant ways as well…

During Meiosis, chromosomes are copied once, and the nucleus divides twice, hence Meiosis I and II. Also, during Mitosis, the chromosomes are copied once as well, but the nucleus divides only once. The cells that are produced by the process of Meiosis contain only half of the genetic material of the parent cell: one chromosome from each homologous pair and one sex…
