Start with a some DNA‚ or RNA if you are so inclined‚ mix in a simple matrix‚ fold the mixture into a protein coat‚ and pour into a plasma membrane. Could this be the recipe for elementary life? Viruses are one of the simplest forms of organized organic material to arise in evolution. They are infamously the most efficient at reproducing while simultaneously eliminating competition which are two of the most fundamental characteristics of life. Despite these remarkable abilities‚ most biologists are

Discuss briefly fluid mosaic model for membrane structure. (6 marks) Answer: The lipids and most of the protein in the plasma membrane are free to bob about‚ sliding from one location in the membrane to another. Because lipids and proteins move about laterally within the membrane‚ the membrane is a fluid mosaic of lipids and proteins. The membrane fluid is since the composition of any location on the membrane can change. In the same manner that a patchwork quilt is mosaic (different fabrics making

The Mosaic Covenant (MC) was designed to have a heavily intertwined relationship with the Abrahamic Covenant (AC). As explained by Professor Robert Letham‚ “The two operated together from the time of Moses until the coming of Christ. They exemplified antithetical principles; unilateral royal grants and a principle of inheritance by works.” (2013‚ 146) Essentially‚ while seeming to oppose each other‚ the MC actually complements the AC. God promised to make Abraham a father of many nations (Gen 17:3)

1. Define "typology." How does this method of interpretation help us understand the Mosaic covenant? Typology is a type of symbolism in which “a person or event in one era of redemptive history that has a specific parallel in another era of redemptive history” (p 178). This method of interpretation helps us understand the Mosaic covenant because it foreshadows and parallels the New Law in the New Testament. It helps build the foundation for New Law‚ and it also shows the people that their God is different

The phospholipids are arranged in a double layer (lipid layer) with the hydrophilic heads facing outward (cytoplasm or ECF) and the hydrophilic tails turned in towards each other. The unsaturated fatty acids are not bonded to each other and form a fluid. Fluid Mosaic model. The term "fluid" is used because the phospholipid molecules

Cell Biology 1 – Prokaryotes & Viruses * Eukaryotes have a membrane whereas a prokaryote has no nuclear membranes. Both have a double stranded DNA. * The two main types of prokaryotes are bacteria and Archaea and eukarya are types of eukaryotes. * Archaea are more closely related to eukaryotes. * Prokaryotes have a membrane and nucleoid and most have a cell wall. * There are 3 main types of shapes of prokaryotes: * Bacillus – rod shapes * Spirilum – spiral shaped

Viruses can infect all types of cells including plant‚ animal‚ protozoa‚ fungi‚ and bacteria. Virus composition is unique and does not resemble a living cell because they only contain the necessary parts to enter and leave an infected cell. A virus is a minute parasite (10 to 100 times smaller than bacteria) that is unable to reproduce by itself; however‚ once it infects a vulnerable cell a virus can make the cell’s inner workings produce viruses on its behalf. Viruses typically have either RNA
