structures of condensed and coiled DNA in the form of chromatin. Chromosomes become visible under the light microscope when cells are preparing to divide.

Card 7
Front
a three-base sequence of DNA or RNA that codes for an amino acid.

Card 8
Front
specific hydrogen bonding between nucleic acid bases. Adenine (A) binds to thymine (T) or uracil (U) and cytosine (C) binds to guanine (G).

Card 9
Front
the molecule responsible for the storage of genetic information.
Back
Card 10
Front
enzyme that catalyses the unwinding and separating of strands in DNA replication.
Back
Card 11
Front
enzyme that catalyses the formation of phosphodiester bonds between adjacent nucleotides in DNA replication.
Back
Card 12
Front
the semi-conservative process of the production of identical copies of DNA molecules.
Back
Card 13
Front
a section of DNA that contains the complete sequence of bases (codons) to code for a protein.
Back
Card 14
Front
the sequences of bases in DNA are the ‘instructions’ for the sequences of amino acids in the production of proteins.
Back
Card 15
Front
short strand of RNA produced by transcription from the DNA template strand. It has a base sequence complementary to the DNA from which it is transcribed, except it has uracil (U) in place of thymine (T).
