monomer

nucleotide

1 of 9

mode of DNA replication in which each strand of a parental double helix acts as a template for the formation of a new molecule, each containing an original, parent strand, and a newly synthesised, complementary daughter strand

semi-conservative replication

2 of 9

a moecule of which the chemical structure determines the chemical structure of another molecule

template

3 of 9

triplet of bases in mRNA that codes for a particular amino acid, or a punctuation signal

codon

4 of 9

the DNA and mRNA base sequences that determine the amino acid sequences in an organism's proteins

genetic code

5 of 9

non-coding nucleotide in DNA and pre-mRNA, that is removed from pre-mRNA, to form mature mRNA

intron

6 of 9

nucleotide sequence in DNA and pre-mRNA that remains present in the final mature mRNA, after introns have been removed

exon

7 of 9

a segment of DNA acts as a template to direct the synthesis of the complementary RNA, with the enzyme RNA polymerase

transcription

8 of 9

the sequence of codons on the mRNA is used to assemble a specific sequence of amino acids into a polypeptide chain, at the ribosomes

translation
