5 Matching questions

  1. Promoters
  2. Extrons
  3. Introns
  4. Steps of Transcription
  5. genetic code
  1. a a non-coding, intervening sequence within a eukaryotic gene
  2. b expressed sequence of DNA; codes for a protein
  3. c Region of DNA that indicates to an enzyme where to bind to make RNA
  4. d the ordering of nucleotides in DNA molecules that carries the genetic information in living cells
  5. e 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

5 Multiple choice questions

  1. The base that pairs with Guanine with DNA
  2. 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
  3. (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. (genetics) the process whereby DNA makes a copy of itself before cell division
  5. an organelle in the cytoplasm of a living cell which attach to mRNA and move down it one codon at a time and stop until tRNA brings the required amino acid; when a ribosome reaches a stop codon it falls apart and releases the completed protein molecu

5 True/False questions

  1. AdenineThe base that pairs with Cytosine in DNA


  2. RNA(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


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


  4. Types of RNARibosomal RNA (rRNA) is the main component of the cell's protein synthesis factory the Ribosome. it is produced by RNA Polymerase I. Transfer RNA (tRNA) is responsible for converting the nucleotide sequence code into the amino acid sequence in proteins. it is produced by RNA Polymerase III. Messenger RNA (mRNA)- each one contains the sequence information needed to construct one type of protein molecule. the multiple mRNA molecules are produced by RNA Polymerase II (bring message from nucleus to cytoplasm)


  5. Steps of Protein Synthesisthe formation of proteins by using information contained in DNA and carried by mRNA
