  3. tRNA
  4. mRNA
  5. semi-conservative replication
  1. a messenger RNA; type of RNA that carries instructions from DNA in the nucleus to the ribosome
  2. b enzyme involved in DNA replication that joins individual nucleotides to produce a DNA molecule
  3. c transfer RNA; type of RNA that carries amino acids to the ribosome
  4. d 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.
