Chapter 13 notes

  1. 1. Chapter 13 NotesIll.Mutations 1. gene mutations(#22,000/46) chromosomes are made up of genes also a chromosome is a diploidsubstitution,(insertion,and deletion) theses are called frame shift the ones in parenthesise 2. chromosomal mutationsdeletion or erase part or all,duplication or copy,inversion or switch,and trans-location or breaks of achromosome then moving different spots.B. effects of mutation 1.mutagensany thing that causes a mutations or (chemical/physical) 2.harmful and helpful mutationsmost are not harmfullv. gene regulation and expressionA.prokaryotic gene regulation 1. the lac operon= a group of genes that regulateE.coli is in the intestine it is your friend and your enemy 2. promoters and operatorsB. eukaryotic gene regulation 1. transcription factors 2. cell specialization 3. RNA interference 4. the promise of RNAi Ch 13 RNA and Protein Synthesis DNA an RNA are both nucleic acids or long chains which is made of nucleotides and thats made out of three parts, sugar base phosphate A.The Role of DNA 1. RNA 2.Comparing RNA and DNA 3. Functions of RNA What is the three differences between RNA and DNA: -messenger RNA/carries info from nucleus -ribosomal RNA -transfer RNA 2.ribosomes 3.mutations B. RNA synthesis 1.transcription/1.enzyme/binds to DNA promoter or areas of DNA where transcript begins step2/DNA unwinds.....step3/rna polymerase makes mRNA using the DNA sense strand 2.promoters 2. ribosomes and protein synthesis A. the genetic code 1. how to read co-dons or tree letters of the code/AUG 2.start and stop co-dons
  2. 2. DNA->RNA->protein proteins are amino acids together
  3. 3. B.translation 1. steps in translation1.mrna attaches to ribosomes/2.erna carrier AA to ribosomes/3 ribosomes attaches into polypeptide chain 2. the roles of tRNA and rRNA in translation
  4. 4. C the molecular basis of hereditycentral dogma of molecular biology
