| leader | A sequence near the 5' end of an RNAstrand or the amino terminus of a protein that functions intargeting or regulation. (09 Oct 1997) |

| leader peptide | <molecular biology> In the regulation of gene expression for enzymes concerned with amino acid synthesis in prokaryotes, the leader sequence codes for the leader peptide that contains several residues of the amino acid being regulated. Transcription is closely linked to translation and if translation is retarded by limited supply of amino acyl tRNA for the specific amino acid, the mode of transcription of the leader sequence permits full transcription of the operon genes, otherwise complete transcription of the leader sequence prematurely terminates transcription of the operon.

| Alu sequences | In the human genome a repeated, relatively conserved sequence of about 300 bp that often contains a cleavage site for the restriction enzyme AluI near the centre; about 1 million copies in the human genome. (05 Mar 2000) |
| regulatory regions or sequences | A DNA base sequence that controls gene expression. (05 Mar 2000) |
| regulatory sequences, nucleic acid | DNA sequences involved in regulating the expression of other genes. (12 Dec 1998) |
| repetitive sequences, nucleic acid | Nucleotide sequences present in multiple copies in the genome. They include direct, inverted, tandem, and terminal repeat sequences and the alu family repeat (named for the restriction endonuclease cleavage enzyme alu I). (12 Dec 1998) |
| chi-sequences | A specific DNA sequence in bacterial genomes that allows for extensive genetic recombination. (05 Mar 2000) |
| tandem repeat sequences | Multiple copies of the same DNA base sequence on a chromosome; used as a marker in physical mapping of the chromosome. (12 Dec 1998) |
| long terminal repeat sequences | Regions of the RNA genome associated with regulation, integration, and expression of retroviruses. (05 Mar 2000) |
