5 Written questions

5 Matching questions

  1. Cytosine
  2. Guanine
  3. Protein Synthesis
  4. Steps of Protein Synthesis
  5. DNA
  1. a the formation of proteins by using information contained in DNA and carried by mRNA
  2. b The base that pairs with Cytosine in DNA
  3. c (biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix EX. associated with the transmission of genetic information; "DNA is the king of molecules"
  4. d DNA strand unwinds and separates, one strand directs synthesis of mRNA, RNA polymerase binds to promoter sequence, nucleotides are added
  5. e The base that pairs with Guanine with DNA

5 Multiple choice questions

  1. initiation; elongation; termination A ribosome assembles on the start codon AUG-->tRNA with the anticodon UAC, and carrying the amino acid methionine, binds to the codon-->tRNA complimentary the the 2nd mRNA triplet binds to its codon-->amino acid that's carried by the 2nd tRNA binds to the methionine-->1st tRNA leaves the P site of the Ribosome and the 2nd tRNA moves there which leaves the A site of the ribosome open for the 3rd tRNA to bind to its codon--> 3rd amino acid is added to the chain
  2. the ordering of nucleotides in DNA molecules that carries the genetic information in living cells
  3. initiation, elongation, termination Transcription unit of DNA--> Upstream from transcription unit is TATA box (promoter)--> May or may not have Enhancer region--> Transcription factors bind to the DNA using the promoter to position itself near initiation site--> TFs prepare DNA for binding of RNA polymerase-->RNA pol separates DNA strands so it can add ribonucleotide triphosphate monomers to the RNA transcript--> RNA Polymerase reads the template strand from its 3'→5' end and the RNA grows from 5'→3'-->RNA Polymerase dissociates and the RNA strand is released
  4. (biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes EX. it transmits genetic information from DNA to the cytoplasm and controls certain chemical processes in th
  5. (genetics) the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm

5 True/False questions

  1. Replication(genetics) the process whereby DNA makes a copy of itself before cell division

          

  2. ribosomeThe base that pairs with Guanine with DNA

          

  3. Types of RNA(genetics) the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm

          

  4. AdenineThe base that pairs with Cytosine in DNA

          

  5. Intronsexpressed sequence of DNA; codes for a protein
