  2. Guanine
  3. genetic code
  4. ribosome
  5. Cytosine
  1. a The base that pairs with Cytosine in DNA
  2. b The base that pairs with Guanine with DNA
  3. c the ordering of nucleotides in DNA molecules that carries the genetic information in living cells
  4. d a non-coding, intervening sequence within a eukaryotic gene
  5. e 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 Multiple choice questions

  1. Region of DNA that indicates to an enzyme where to bind to make RNA
  2. (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
  3. expressed sequence of DNA; codes for a protein
  4. The base that pairs with Thymine in DNA
  5. the formation of proteins by using information contained in DNA and carried by mRNA

5 True/False questions

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


  2. 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)


  3. thymineThe base that pairs with Cytosine in DNA


  4. DNA(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. Steps of Translationinitiation; 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
