5 Written questions

5 Matching questions

  1. Replication
  2. thymine
  3. ribosome
  4. genetic code
  5. DNA mutation
  1. a the ordering of nucleotides in DNA molecules that carries the genetic information in living cells
  2. b The base that pairs Adenine in DNA
  3. c When an error is made during DNA replication. It is the basis of all genetic variability. If there is a mistake in DNA replication then the RNA is affected, so amino acids and proteins are affected too.
  4. d 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. e (genetics) the process whereby DNA makes a copy of itself before cell division

5 Multiple choice questions

  1. DNA strand unwinds and separates, one strand directs synthesis of mRNA, RNA polymerase binds to promoter sequence, nucleotides are added
  2. a non-coding, intervening sequence within a eukaryotic gene
  3. Region of DNA that indicates to an enzyme where to bind to make RNA
  4. The base that pairs with Guanine with DNA
  5. (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

5 True/False questions

  1. GuanineThe base that pairs with Thymine in DNA

          

  2. Steps of Transcriptioninitiation; 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. RNA(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"
