Eukaryotic Cells Essay

There are two types of cells known to humanity, eukaryotic cells and prokaryotic cells. Prokaryotic meaning” before or pro nucleus”, is a cell that has no nucleus; however does contain a plasma membrane, ribosomes, cytoplasm and genetic material (DNA and RNA). Occasionally some prokaryotic cells also may have a flagellum or pili- used for movement of the cell. Flagellum is a tail like structure, cells usually contain only 1 or 2,as for pili they are hair like structures and there are an abundance

1. Compare and contrast prokaryotic and eukaryotic cells. Be sure to address cell structure, replication (including DNA replication) and gene expression. The cell structure of prokaryotic organisms is small, only about 1-10 microns in length, and they are also single celled. Prokaryotes contain circular DNA which is held in the nucleoid because they lack a nucleus. The specific organisms that have circular DNA are: mitochondrial, bacterial (eubacteria), and Archaea (Methanobacteria, Halobacteria

1. Explain the advantages of compartmentalization in eukaryotic cells. Compartmentalization provides advantages in Eukaryotic cells because it provides the optimal environment for different metabolic functions. So many metabolic functions can happen inside one cell. 2. Explain how the nucleus controls protein synthesis in the cytoplasm. The nucleus creates mRNA and the mRNA goes through the nuclear pores into the cytoplasm. The mRNA is transcribed the from the DNA. Once the mRNA enters the cytoplasm

dissimilarity between eukaryotic and prokaryotic cells is quite apparent and diverse. One of the major differences between the cells is their size. Prokaryotic cells usually range from 0.2 μm to 10 μm while the size of eukaryotic cells range from 10 μm to 100 μm. Additionally, prokaryotic cells have no nucleus and instead store DNA in a circular nucleoid that floats freely. Eukaryotic cells, on the other hand, have a nucleus with a double membrane nuclear envelope. Many prokaryotes have cell walls that are

(DNA) is a macromolecule that has the power of carrying the genetic information for all the proteins that make up an organism and controls their quantity of production. It is known to be located inside the nucleus in all eukaryotic cells, but lies in the cytoplasm in prokaryotic cells (1, 3). In 1953, Watson and Crick came up with a model to describe the structure of DNA as a double-helix containing two chains that have opposite endings labeled 5’ and 3’, and an anti-parallel orientation, meaning that

DNA is a nucleic acid that carries the genetic information in cells, it consists of two long chains of nucleotides (a nitrogenous base, a five-carbon sugar and a phosphate group) twisted into a double helix that are joined by hydrogen bonds, where between of them there are the complementary bases: that are Adenine and Thymine or Cytosine and Guanine. DNA is the structure of life; it is where all the information of how you are is. This nucleic acid composes chromosomes that are packaged and organized

article related to Eukaryotic cells describes how organisms are comprised of cells that is also referred to as the building blocks of life. All cells enable organism to ingest food, decompose waste, and reproduce. Therefore, in order for a cell to perform the three primary operations successfully within the plasma membrane, nucleus, and cytoplasm. There are organisms that consist of one cell (unicellular) as to other organisms are complex, thereby, made up of trillions of cells (multicellular). In

Eukaryotic cells respond to cellular stress by controlling the translation, stability and subcellular localization of mRNA (Buchan, Yoon, & Parker, 2011). This occurs through the remodeling of translating mRNAs into non-translating mRNPs which accumulate in cytoplasmic RNA- protein granules, known as P-bodies (mainly contain mRNA decay machinery) and stress granules (mainly contain translation initiation factors). (Buchan, Yoon, & Parker, 2011). Several studies reveal that both granules share specific

Holy Martyrs Ferrahian High School Reproduction, Symbiosis, and the Eukaryotic Cell Research Paper Aram Kazorian AP Biology Mrs. Lee 18 October, 2016 The research that was conducted had the specific purpose of addressing questions on topics of individuality, reproduction, symbiotic relationships, all based around the idea of endosymbionts and the endosymbiotic theory with the eukaryotic cell. Symbiosis are the relationships between organisms that can either harm or benefit themselves

prokaryotic and eukaryotic cell are different in many ways.A prokaryotic cell means a microscopic single celled organism that has neither a distinct nucleus with a membrane,and mitochondria,or an membrane bound organelle.The prokaryotic cell is like an apartment, it supports the person with living space, but is small and simple at the same time.An eukaryotic cell is any organism whoose cell contains an nucleus, and other membrane bond and organells.An example of an eukaryotic cell is an mansion.An
