Monomer of nucleic acid comprising a pentose sugar, nitrogenous sugar and a phosphate sugar
1 of 8
Semi-conservative replication
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, parental stand, and newly synthesised, complementary daughter strand
2 of 8
Codon
Triplet of bases in mRNA that codes for a particular amino acid, or a punctuation signal
3 of 8
Genetic Code
The DNA and mRNA base sequences that determine the amino acid sequences in an organism's proteins
4 of 8
Intron
Non-coding nucleotide sequence in DNA and pre-mRNA, that is removed from pre-mRNA, to produce mature mRNA
5 of 8
Exon
Nucleotide sequence in DNA and pre-mRNA that remains present in the final mature mRNA, after introns have been removed
6 of 8
Transcription
A segment of DNA acts as a template to direct the synthesis of a complementary sequence of RNA, with the enzyme RNA polymerase
7 of 8
Translation
The sequence of codons on mRNA is used to assemble a specific sequence of amino acids into a polypeptide chain, at the ribosomes
