Daily TAKS Connection: Replication, Transcription, Translation BIO(6): The student knows that the structures and functions of nucleic acids in the mechanisms of genetics. The student is expected to: (B) Explain replication, transcription, and translation using models of DNA and RNA. Day 1 Construct a three tab foldable Instructions: Materials: Foldable handout Scissors Pen Colored pencils/crayons Hotdog fold paper along center line Cut tabs from edge to center along dotted lines Color each flap a different color Day 2 notes Record the following notes under the flap labeled “Replication” DNA synthesis DNA → DNA Occurs in the nucleus 1. DNA double helix unwinds; 2. separates at hydrogen bond between base pairs DNA polymerase adds base pairs to both strands Adenine complements 3. Thymine Guanine complements Cytosine Two “New” DNA molecules formed– one strand original, one strand new Question DNA passes information to new DNA during the process of — a. replication b. transcription c. translation d. osmosis Question Which of the following must occur before DNA replication can take place? a. Translation of DNA into amino acids b. Separation of the DNA molecule into codons c. Transformation of DNA into RNA d. Separation of the DNA double helix Question Part of a DNA strand is represented in the diagram shown. In order for DNA to replicate, the strand must separate at which of the following locations? a. Between every phosphatesugar pair b. Between the eight sugar-base pairs c. Between the four nitrogenous base pairs d. Between any two chemical bonds Question If the template of a strand of DNA is 5' TCTACGTAG 3', the complementary strand will be — a. 3' TCTACGTAG 5' b. 5' CTACGTAGA 3' c. 3' AGATGCATC 5' d. 5' AGACGTCTA 3' Day 3 notes Record the following notes under the flap labeled “Transcription” RNA synthesis DNA → RNA Occurs in the nucleus Adenine from DNA complements Uracil in RNA Thymine from DNA complements Adenine in RNA Guanine from DNA complements Cytosine in RNA Cytosine from DNA complements Guanine in RNA Question DNA passes information to RNA during the process of — a. replication b. transcription c. translation d. osmosis Question 3' CGGUAU 5' This is a short section of mRNA. Which DNA code probably produced this section of RNA? a. 3' GCCTUT 5' b. 5' GCCAUT 3' c. 3' ATTGCC 5' d. 5' GCCATA 3' Question Which of these represents the DNA segment from which this section of mRNA was transcribed? a. ACTAAG b. TCUTTG c. GAAUCU d. UCCTGA Question The diagram shows how an mRNA molecule is synthesized. What would be the most likely result if a bacterial infection stopped the production of the RNA polymerase? a. A protein could not be manufactured. b. A lysosome would digest the cell. c. Osmosis would not occur in the cell. d. Dehydration could be prevented in the cytoplasm. Day 4 notes Record the following notes under the flap labeled “Translation” Protein synthesis RNA → protein Occurs at the ribosomes Codons (3 base sequence) code for amino acids Use codon chart to determine amino acid Amino acids link together to form protein Day 4 Student Task Using the codon chart, transcribe the RNA nucleotide sequence below: UUCACGGAAUGG Question RNA is used to code for proteins during the process of — a. replication b. transcription c. translation d. osmosis Question Translation (protein synthesis) takes place in a cell at the – a. nucleus b. mitochondria c. ribosome d. cell membrane
