According to Aristotle‚ a tragic hero in a Greek drama must meet certain requirements. The tragic hero must be of noble birth‚ be basically good‚ must have a tragic flaw‚ and must have a moment of realization at some point in the work. Although Antigone is the namesake of the Sophocles play and is a hero in her own right‚ she is not a tragic hero. Creon is the true tragic hero of Antigone in the traditional sense of the term. Both Antigone and Creon were born of noble blood as they are members

TRANSCRIPTION: Transcription is the process of which DNA matches corresponding RNA bases‚ Transcription is located in the Nucleus‚ and the only type of RNA that is involved in Transcription is mRNA‚ and the purpose is so that the code can get out of the Nucleus‚ mRNA is also made through Transcription‚ It also takes information that doesn’t directly make proteins but it helps makes codes for the production of proteins‚ DNA Transcription consist of 4 nucleotide bases‚ Adenine‚ Thymine‚ Cytosine‚ Guanine

Biology Cell DNA Transcription mRNA Translation Ribosome Polypeptide (protein) Protein Synthesis Flow of Information: DNA RNA Proteins Transcription Translation Transcription is the process by which a molecule of DNA is copied into a complementary strand of RNA. This is called messenger RNA (mRNA) because it acts as a messenger between DNA and the ribosomes where protein synthesis is carried out.

Once someone understands the makeup of a protein‚ they can then begin to learn how elements can combine and go from genes to protein. There are two main processes that occur during protein synthesis‚ or peptide formation. One is transcription and the other is translation. Although these biological processes slightly differ for eukaryotes and prokaryotes‚ they are the basic mechanisms for which proteins are formed in all living organisms. There are four main levels of a protein‚ which make

Transcription The Central Dogma RNA Polymerase Ribosome DNA transcription replication RNA translation Protein One gene encodes one protein? (Beadle and Tatum‚ 1941) • • • Cellular machinery is largely made up of proteins. Proteins are made up of chains or sequences of amino acids. The sequence of these amino acids are "encoded" in the cell’s DNA. DNA is transcribed into RNA‚ which is then translated into protein. When one gene is mutated‚ one protein is affected (usually

Ideas and Using Concepts: P.258-259 Reviewing Ideas: 1. Describe the function of tRNA‚ mRNA‚ and rRNA. The function of tRNA is to delivers amino acid to ribosomes during translation in the order specified by the mRNA. The function of mRNA is to specify which amino acids must be placed during protein synthesis or translation. The function of rRNA is just to become part of the ribosomes. 2. In what situation does RNA play a role similar to enzymes? RNA is like an enzyme when it is a catalyst

17.1 Genes specify proteins via transcription and translation * George Beadle and Edward Tatum worked together with mutated (Neurospora crass) bread mold to figure out that they were missing a specific enzyme (gene) that catalyzed and synthesized a pathway required. They concluded that they were missing that enzyme because it was lacking the amino acid that coded for the enzyme‚ thus was mutated and incapable of growing. Led to the one enzyme-one gene hypothesis. The Products of Gene Expression:
