1 RNA and PROTEIN SYNTHESIS Chapter 13
2 DNA Double stranded Thymine Sugar is RNA Single stranded Uracil Sugar is Ribose Deoxyribose
3 Types of RNA 1. Messenger RNA (mrna) Carries copies of instructions from DNA to ribosomes 2. Ribosomal RNA (rrna) Important component of ribosomes 3. Transfer RNA (trna) Carries amino acids to ribosomes during protein synthesis
4 rrna
5
6 Transcription = Synthesis of RNA from DNA template Eukaryotes Occurs in nucleus Prokaryotes Occurs in cytoplasm Translation = mrna is converted into sequence of amino acids of a protein Eukaryotes AND prokaryotes Occurs in cytoplasm at ribosomes
7
8 RNA Synthesis: Transcription
9 Promoter = Specific region of a gene where RNA polymerase binds and begins transcription RNA polymerase = Enzyme that links RNA nucleotides using DNA as a template Adds complementary RNA nucleotides along DNA template strand -RNA s Cpairs with DNA s G -RNA s Gpairs with DNA s C -RNA s Apairs with DNA s T -RNA s Upairs with DNA s A Synthesized in 5 to 3 direction
10
11 Let s Practice! DNA template strand C CT A G C T A C RNA G GA U C G A U G DNA coding strand G GA T C G A T G
12 RNA Editing Introns = Sequences of DNA that are not involved in coding for a protein Transcribed but then removed before translation Exons = Sequences of DNA that code for proteins Spliced back together to be translated Cap is added to 5 end Recognition site for protein synthesis Poly A tail is added to 3 end Necessary for protein synthesis to begin May also stabilize mrna so it stays intact longer Mature mrna exits the nucleus to be translated
13
14 Protein Synthesis: Translation
15 Genetic code = Correspondence between specific mrna triplets and the amino acids they specify Codon = Group of 3nucleotide bases in mrnathat specify a particular amino acid AUG is the start codon UGA, UAA, and UAG are stop codons Universal All species use the same mrna codons to specify the same amino acids
16
17 Let s Practice! mrna AUGGGAUGUAAGCGAUAA mrna codons AUG GGA UGU AAG CGA UAA Amino Acid Met Gly Cys Lys Arg (STOP)
18 Steps in Translation to Build a Protein Ribosome attaches to mrna in cytoplasm Proper amino acids are brought to codons with help of anticodons = Group of 3 bases on trnathat are complementary to mrna codon and carry appropriate amino acid
19 Start codon (AUG) attracts trna carrying the amino acid methionine (Met) Indicates start of polypeptide trna brings next amino acid to A site of ribosome P site next to it holds growing amino acid chain Peptide bondforms between adjacent amino acids, creating a polypeptide chain When Stop codon reaches the A site, the new polypeptide and mrna are released
20 Let s Practice! DNA TACGGTCGTTCGAATATC mrna codons AUG CCA GCA AGC UUA UAG trna anticodons UAC GGU CGU UCG AAU AUC Amino Acid (remember to use the codons!) Met Pro Ala Ser Leu (STOP)
21 Protein Modification Proteins fold into one or more 3-D shapes Remember, shape affects function! Chaperone proteins = Binds a polypeptide and guides folding Proteasome = Refolds or dismantles misfolded proteins Example of folding error: Sickle cell disease Red blood cells are bent out of shape
22 Mutations
23 Mutation= Change in the genetic material of a cell Alters DNA sequence May or may not affect phenotype 2 basic categories: Chromosomal mutations Gene mutations Point mutations =»Single base pair in DNA is changed»generally occur during replication»ex: Substitutions, insertions, deletions
24 Substitution = One base is changed to a different base Results in change of one codon Examples Missense mutation = One amino acid is altered Nonsense mutation = Protein is shortened because new codon is a STOP codon Silent mutation = No change in amino acid 3 rd base of triplet was altered to codon that specifies the same amino acid
25 Frameshift mutations = Shifts reading frame of genetic message Alters every amino acid that follows the mutation Examples Insertion = One base is added to DNA sequence Deletion One base is removed from DNA sequence Note: If bases are inserted/deleted in multiples of 3, reading frame is not altered
26 Effects of mutations Mutagens = Agents in environment that interact with DNA and may cause a mutation by: Interfering with base pairing Increases errors in DNA replication Weakening DNA strand Examples Causes breaks and inversions on chromosomes Chemical Pesticides, tobacco smoke, environmental pollutants Physical Radiation (X rays, UV light)
27 Harmful effects Cancer and other genetic disorders Beneficial effects Resistance Polyploidy = extra sets of chromosomes Results in larger and stronger plants Increase genetic variability in a species Many mutations are neutral May not even change any amino acids
28 Gene Regulation and Expression
29 Prokaryotes DNA binding proteins regulate genes by controlling transcription Switch genes on and off Operon= Group of genes that are regulated together Ex: Lacoperon If lactose is not present, lacgenes are turned off
30 Promoter= Site where RNA-polymerase binds to begin transcription Operator= Site where lacrepressor can bind to DNA Lies between promoter and operon If lacrepressor binds to operator Operon is turned off If lactose is present, it removes repressor Operon is turned on
31 Eukaryotes Transcription factors = Proteins that activate the transcription of certain genes Open up tightly packed chromatin Block access to certain genes Attract RNA polymerase via TATA box (promoter) Control sequence near the start of a gene Composed of bases TATA surrounded by long stretches of G and C
32 Gene regulation helps cells undergo differentiation = Cells become specialized in structure and function Homeotic genes = Regulate organs that develop in specific parts of the body Mutation can transform one body part into another Homeoboxgene= Codes for transcription factors that activate genes important in cell development and differentiation Determine factors like presence of wings or legs
33 Environmental Influences Environmental conditions also play a role in gene expression Temperature Salinity Nutrient availability
