Prokaryote

life in to two main cellular groups; the eukaryote-prokaryote dichonomy (cited in Sapp, 2005), as well as Whittaker’s Five Kingdom system to organise all living things (Whittaker, 1969), they do not co-exist compatibly or correctly. The five kingdom system is not phylogenetically correct and eukaryote and prokaryote systems do not take into consideration new sequencing abilities (Kandler, Wheelis & Woese, 1990). These previous taxa are outdated because they do offer readily available, accurate or historical information. Whilst previously grouping eukaryotes and prokaryotes using cellular data, currently on a molecular level, sequencing gives us a…

Biology is the study of living or deceased organisms (Biology Department, 2015). There are two overarching classes to these organisms: prokaryotes and eukaryotes (Reece et al., 2014). Prokaryotes (meaning before nucleus) are put in two domains: Bacteria and Archea (Biology Department, 2015). Eukaryotes on the other hand, (which have nuclei), are in the Eukarya domain and encompass all other organisms such as plants, animals, fungi and protists (Biology Department, 2015). The most effective way…

range that I came up with is approximately 140 to 300 micrometers for the Paramecium caudatum. The average length of the Paramecium caudatum was 0.0488 µm. 4. What subcellular feature did you recognize and identify in all of the organisms you examined? • We noticed the cell wall or the plasma membrane of each of the organisms. In the Rotifer that we saw, we also seen what looked to be part of the digestive system, including the mouth, and butt of the Rotifer. 5. Did you examine any prokaryotes…

a Prokaryotic from a Eukaryotic organism? My Answer: E) All of the above Correct Answer: C) Membrane bound nucleus Why my answer was wrong: I was thinking more about plant versus animal. I definitely know the difference between prokaryotic cells and eukaryotic cells, I guess I just got nervous or confused. The presence of a cell wall, presences of a plasma membrane, and ribosomes, are all characteristics of both a Prokaryotic cell and a Eukaryotic cell. Plants, fungi, and protists which are…

The aim of the data analysis exercise was to determine genetic relationships between the HSP70 amino acid chains of fourteen different organisms. The data produced was an identification table, a sequence alignment diagram and a cladogram. In cladograms the branches are not representative of the evolutionary time that has occurred. Heat shock proteins (HSPs) are in a class of proteins called molecular chaperones. (Kiang, J.; G, Tsokos. 1998). They are present in both eukaryotes and prokaryotes,…

cells are observed; eukaryotic cell and the prokaryotic cell. Each of these cell play a different role based on its distinction; in fact, their distinction is the most important distinction among organisms. Carl Woese in the Introduction to the Archaea UCMP website provided research which would divide prokaryotes into the following two groups: archaea and bacteria. Thus, the development of the three domains was created to include archaea, bacteria, and eukaryotic domains. During the course…

eukaryotes. In addition, the theory that domains from unicellular eukaryotes were shuffled around and passed on to multicellular eukaryotes for like functions is similar to how prokaryotic bacteria are involved in the evolution of apoptosis. Many domains such as the MATH or BIR domains are found in both prokaryotic cells and mammalian cells. Although, in the mammalian cells those domains form the outer layer of the apoptotic machinery and has different functions than it served while in the…

There are two main types’ of cells. These are prokaryotic (see diagram 1) and Eukaryotic. ( See diagram 2). Prokaryotic cells are the cells of microorganisms such as Bacteria and Achaea. Eukaryotic cells are basically cells that make all other living things such as humans and animals. You can identify the difference between these cells by their structure they both have a number of features in common but all so lots of differences. The eukaryotic cell has a membrane enclosed organelle called…

be considered if the component trying to be cultured is a prokaryotic or a eukaryotic cell, as the two require notably different conditions in order to develop. The most notable difference between the two requirements is that most eukaryotic cells require oxygen in their environments in order to survive, wherein prokaryotes can survive in environments with little to no oxygen and can develop with only a small assortment of nutrients. Therefore, lines can already be drawn as to what media should…

In both prokaryotes and eukaryotes, it is a complex multistep process that’s regulated by a variety of enzymes and proteins. Prokaryotic and eukaryotic DNA replication are both bi-directional processes, the DNA polymerases work from the 5’ to the 3’ end, they both involve leading and lagging strands and primers are required2. The main differences result from the difference in complexity between both types of organisms. While prokaryotic DNA is circular, eukaryotes have linear chromosomes with…
