ANTH 110 1nd Edition Lecture 5 Outline of Last Lecture I Summary of Natural Selection II Introduction to DNA A DNA structure B DNA function C Protein Synthesis D Replication Outline of Current Lecture I DNA Function A Protein Synthesis Overview II Genes III Anthropologists and DNA Current Lecture I DNA Functions DNA directs protein synthesis Human beings consist of many proteins Proteins are major structural components of tissue Collagen which is in connective tissues is a protein It is in blood cartilage bone and fats Hemoglobin is also a very important protein Enzymes and hormones are made up of protein Enzymes i e lactase serve as catalysts in cellular functions What proteins are formed is determined by the arrangement of bases in our DNA or our DNA code A Protein Synthesis Overview These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute Protein Synthesis occurs in the ribosomes within a cell After the RNA has been formed within the nucleus through transcription it exits the nucleus and finds a ribosome Here the genetic message in DNA is converted into proteins Every series of 3 RNA bases or a codon is matched with an anti codon This pairing results in an amino acid being created Each anti codon corresponds with a particular amino acid There are 60 variations of anti codons but only 21 amino acids that can be produced from them Thus more than one anti codon can create each amino acid There are start and stop codons that signal ribosomes to start and stop attaching anti codons thus ending the amino acid chain Step by Step First transcribe transcription DNA into mRNA This process is similar to replication Second translate translation the mRNA into chains of amino acids Lastly the amino acid chain then folds into specific proteins II Genes Our genes are packed into DNA and our DNA is packed into chromosomes We each have 46 chromosomes Sequence variation is what
