5 Matching questions

  1. Adenine
  2. Translation
  3. Replication
  4. genetic code
  5. DNA
  1. a (genetics) the process whereby DNA makes a copy of itself before cell division
  2. b (genetics) the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm
  3. c The base that pairs with Thymine in DNA
  4. d the ordering of nucleotides in DNA molecules that carries the genetic information in living cells
  5. e (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"

5 Multiple choice questions

  1. 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.
  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. a non-coding, intervening sequence within a eukaryotic gene
  4. expressed sequence of DNA; codes for a protein
  5. (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 True/False questions

  1. Protein SynthesisDNA strand unwinds and separates, one strand directs synthesis of mRNA, RNA polymerase binds to promoter sequence, nucleotides are added

          

  2. thymineThe base that pairs with Thymine in DNA

          

  3. ribosomeThe base that pairs with Guanine with DNA

          

  4. Types of 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

          

  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
