5 Matching Questions

  1. Transcription
  2. genetic code
  3. Cytosine
  4. Steps of Protein Synthesis
  5. Protein Synthesis
  1. a (genetics) the organic process whereby the DNA sequence in a gene is copied into mRNA EX. the process whereby a base sequence of messenger RNA is synthesized on a template of complementary DNA
  2. b the formation of proteins by using information contained in DNA and carried by mRNA
  3. c DNA strand unwinds and separates, one strand directs synthesis of mRNA, RNA polymerase binds to promoter sequence, nucleotides are added
  4. d the ordering of nucleotides in DNA molecules that carries the genetic information in living cells
  5. e The base that pairs with Guanine with DNA

5 Multiple Choice Questions

  1. Region of DNA that indicates to an enzyme where to bind to make RNA
  2. (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"
  3. The base that pairs with Thymine in DNA
  4. 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. expressed sequence of DNA; codes for a protein

5 True/False Questions

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

          

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

          

  3. thymineThe base that pairs with Cytosine in DNA

          

  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. GuanineThe base that pairs with Cytosine in DNA
