5 Written questions

5 Matching questions

  1. semi-conservative replication
  2. codon
  3. human genome
  4. nucleotide
  5. nitrogenous base
  1. a The building block of a nucleic acid, consisting of a five-carbon sugar covalently bonded to a nitrogenous bas and a phosphate group.
  2. b carbon ring structure found in DNA or RNA that contains one or more atoms of nitrogen; includes adenine, guanine, cytosine, thymine and uracil
  3. c three-nucleotide sequence on messenger RNA that codes for a single amino acid
  4. d Complete set of genetic information
  5. e The way in which DNA is synthesized. Each of the two partner strands in a double helix acts as a template for a new partner strand. Hence, after replication each double helix consists of one old and one new strand.

5 Multiple choice questions

  1. ribosomal RNA; type of RNA that makes up part of the ribosome
  2. the transfer of genetic material in the form of DNA fragments from one cell to another or from one organism to another
  3. complementary nitrogenous bases are bonded by these weak bonds
  4. enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule
  5. transfer RNA; type of RNA that carries amino acids to the ribosome
