A ribosome is a complex cellular mechanism used to translate genetic code into chains of amino acids. Long chains of amino acids fold and function as proteins in cells.
The function of a ribosome in any cell is to produce proteins. Proteins are used in almost all cellular functions; as catalysts they speed the time of reactions, as fibers they provide support, and many proteins function in specific tasks, like contracting muscle cells. All proteins start as deoxyribonucleic acid, or DNA. A special protein, RNA pol...
Ribosomes have an incredibly similar structure throughout all forms of life. Scientists attribute this to the ribosome being a very effective and efficient way of synthesizing proteins. Thus, early in the evolution of the various forms of life, the ribosome was universally adopted as the method for translating RNA into proteins. Ribosomes therefore...
Ribozyme– RNA that acts as a biological catalyst, which in a ribosome helps form peptide bonds.Ribosomal RNA– RNA molecules associated with ribosomes, some of which are ribozymes and catalyze reactions.Ribonucleic Acid– Otherwise known as RNA, this molecule usually exists as a single-stranded carrier of genetic information.Deoxyribonucleic Acid– DNA, or the double-stranded and very stable molecule that contains the genetic information of most life on earth in the form of variable sequences of 4 different base-pairs.1. A scientist studying viruses is trying to find a way to stop them from reproducing. The scientist finds a way stop ribosomes from forming, which he determines also stops viruses from reproducing. Why will this method not work? A. The virus can still reproduce its genome. B. The host cell also needs the ribosomes. C.The virus will not be able to ...

Dec 18, 2016 · The Elements of Life Overview. The overarching theme of Unit 1.2 is “The Elements of Life.”. Before getting into the complex macromolecules that organisms need to survive, we must first understand that there are several elements that all life is dependent on: Carbon, Hydrogen, Oxygen, Nitrogen, Sulfur, and Phosphorus.
