5 Matching questions

  1. Codon
  2. rRNA
  3. Nucleotides
  4. 3' refers to
  5. For cells to multiply
  1. a Includes 1) Phosphate group 2) 5 carbon sugar -> Deoxyribose 3) Nucleotides bond covalently between the 5'PO4 of one nucleotide and the 3'OH of another -> Joining of nucleotides creates an alternating sugar-phosphate backbone
  2. b 3'OH -> 1 strand of the DNA has a hydroxyl group attached to the number 3 carbon of the sugar. -> Termed the three prime (3') end
  3. c 1) DNA replication 2) DNA expression (gene expression)
  4. d Ribosomal RNA -> type of RNA molecule present in ribosomes. rRNA builds the ribosomes
  5. e 1) Codons are groups of three nucleotides situated next to each other on DNA 2) Codons are written in terms of their base sequence in mRNA 3) The sequence of codons determines the sequence of amino acids in the protein 4) There are 64 codons that make up the "alphabet" of proteins 4.1) Of the 64 codons, 61 are sense codons -> Each coding a specific amino acid 4.2) The remaining 3 are nonsense codons -> These code for termination of the message 5) Codons contained in mRNA are read into proteins through translation -> The site of translation is the ribosome 6) Each codon has an anticodon -> The anticodon is complementary sequence to the codon

5 Multiple choice questions

  1. Transfer RNA -> type of RNA molecule that acts as a key, interpreting the genetic code; each tRNA molecule carries a specific amino acid. tRNA recognizes specific sequences of mRNA and transports the required amino acids to form a polypeptide chain
  2. 1) Made up of deoxy-ribonucleotides 2) Nucleotides bond covalently between the 5'PO4 of one nucleotide and the 3'OH of another 3) Each sugar (deoxyribose) molecule is connected to a nitrogenous base 4) Chemical structure and joining of nucleotide subunits causes strands to differ at the ends 5) DNA occurs as double-stranded molecule 5) DNA molecule is antiparallel
  3. Replication is bidirectional -> Replication begins at specific starting point -> Proceeds in opposite directions -> Allows replication to proceed more quickly
  4. RNA is deciphered to synthesize protein 1) Two more RNA molecules become involved in translation 1.1) Ribosomal RNA (rRNA) 1.2) Transfer RNA (tRNA) 2) The language of mRNA is in the form of codons 3) There are 64 codons that make up the "alphabet" of proteins 4) Codons contained in mRNA are read into proteins through translation 4.1) The site of translation is the ribosome 4.2) In response to each codon, tRNA brings the appropriate amino acid to the site of translation 4.3) Each codon has an anticodon -> The anticodon is complementary sequence to the codon
  5. Mechanisms to enhance survivability 1) Antigenic variation 2)

5 True/False questions

  1. TerminatorTransfer RNA -> type of RNA molecule that acts as a key, interpreting the genetic code; each tRNA molecule carries a specific amino acid. tRNA recognizes specific sequences of mRNA and transports the required amino acids to form a polypeptide chain

          

  2. Reading frameSequence at which RNA synthesis stops; the RNA polymerase falls off the DNA template and releases the newly synthesized RNA.

          

  3. (T)Guanine

          

  4. (A)Adenine

          

  5. Central dogma of molecular biologyFlow of information from DNA to RNA to protein
