Archaea And Eukaryotes

Improved Essays
Within the study of microorganisms, two types of 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 of this Session Long Project I will define the general characteristics which determine whether a prokaryote belongs to the Archaea or Bacteria domain. I will define and discuss the role in which DNA and …show more content…
Archaea and bacteria groups differ as the prokaryote are similar in some characteristics but also have unique traits to one another. According to UCMP website archaea are characterized by membranes which are “branched hydrocarbon chains attached to glycerol by either linkage” (UCMP-Archaes: Systematics, 2014). These organisms also have a unique characteristic of being able to withstand high temperatures as well as conditions which are acidic. In contrast, the bacteria domain prokaryotes’ membranes are made of “unbranched fatty acid chains attached to glycerol by ester linkages” (UCMP- Introduction to bacteria, 2014). Another unique characteristic to this domain is its diversity despite bacteria’s causing diseases they also help produce antibiotics and help break down dead organic matters its great flexibility makes them extremely important in our echo …show more content…
Oceani’s metabolism structure involves oxidized ammonia into nitrite in order to create energy. The organism utilizes this for energy in addition to the participating in the sulfur cycle. “As Ammonia is transported into the cell, it passes by the membrane bound hertero-timeric copper ammonia monoxygenase enzyme to by oxidized to hydroxylamine”. Nitrosopumilus maritimusas also oxidizes ammonia into nitrite and it is believed that it additionally enters into autotrophic metabolism. This was theorized based on discovered parallels between the amount of marine nitrite which existed in the organism and the amount of Crenarchaeota found within the

    In microorganisms metal resistance character is regulated by genes which are organized in operons. Commonly, the heavy metal resistance genes are found on plasmid carried by metal resistant bacteria. In the presence of specific metals in the vicinity of bacterial niche the heavy metal resistance genes are expressed and induced. The regulation of expression of metal resistant gene is specific for each heavy metal and is dependent upon metal species concentration. The promoter and regulator genes of the bacterial operons responsible for resistance property and can be used to form metal-specific biosensors.…

    According to Jun et all. (2012) “The recently-solved X-ray crystal structures of archaeal RNA polymerase (RNAP) allow a structural comparison of the transcription machinery among all three domains of life” (abstract). When it comes to bacteria Yun et all. (2015) states that transcription by RNA polymerase (RNAP) in bacteria requires specific recognition by σ factors (p. 882). Griffiths et all (2000) says that transcription relies on the pairing of the nitrogenous bases of DNA.…

    As described in the central dogma of biology, information from a gene can be used to build a protein in a two-step process. Transcription is considered to be the first step of gene expression. It is known to be the process of making a copy of genetic information stored in a DNA strand into a complementary strand of messenger RNA (mRNA). The process of eukaryotic transcription can be separated into three phases, initiation, elongation and termination. This complex process involves various cell signaling methods as well as the activity of many enzymes.…

    The objective of this lab was to isolate and identify an unknown Gram positive and Gram negative bacteria through the use of various microbiological techniques. The identification of the genus and species for the unknown culture should be obtained based on the characteristics for Gram positive and Gram negative bacteria. Bacteria are prokaryotic microorganisms that lack a nucleus and therefore all its genetic information is stored in the cytoplasm of the cell. The bacterial cell envelope protects the cell and consists of a cell membrane(s) and a cell wall. The cell membrane surrounds the cytoplasm is composed a phospholipid bilayer which contains hydrophobic membrane proteins (Slonczewski & Foster, 2015).…

    As explained by our textbook, “the chemical composition of the cell wall helps to differentiate major types of bacteria” (Tortora, Funke, and Case 84). The two main types of bacteria are gram positive and gram negative. Their cell walls are composed of peptidoglycan. The peptidoglycan is a chain of repeating disaccharide held together by polypeptides. The disaccharide…

    Construction of DNA, RNA, And Protein By Building Models Introduction Nucleic acids are made of nucleotides. When these nucleic acids form sequences they create either DNA or RNA. DNA and RNA are composed of a phosphate, a sugar, and a nitrogen base. The main difference in RNA and DNA is that uracil replaces the base of thymine in RNA. Proteins are essential to maintaining cells by creating hormones and enzymes, and defending the cell.…

    Bacteria can be classified either gram-positive or gram-negative. These groups differ by the composition of their cell walls. In particular, the difference in the composition pertains to amount of peptidoglycan, a polymer of amino acids and sugars, present. A Gram test is most commonly used for this classification, and pertains to using a dye to determine the classification of the bacteria. The peptidoglycan that is found…

    In this system, CRISPR arrays are transcribed into an RNA molecule (guide RNA) and then processed into CRISPR RNAs (crRNA) to guide Cas9 nuclease activity against specific portions of the DNA or RNA of the pathogen [6]. The activity of the guide RNA, which can bind specifically to a sequence of nucleic acids and target the Cas9 nuclease activity, allows the CRISPR-Cas9 technique to be used to edit the genome of bacteria like Streptococcus thermophilus, Escherichia coli, and also of mammalian cells in a specific way. This way, if we use different guide RNAs, we can target specific regions of the genome and, as a result, target the nuclease activity of Cas9 to edit a desired region of the genome…

    Genetic mutations are the source of numerous hereditary diseases. This has been discovered by the comparison of two DNA sequences with bioformatic software. Two sequences are aligned and compared in order to locate mutations in the DNA (Module 4 Protocol,1). Escherichia coli aka E. coli was used as the test subject in this lab because it employs lac operons while transcribing mRNA. An operon is a unit of linked genes that regulates genes in charge of protein synthesis.…
