The following is a partial list of the "G" codes for Medical Subject Headings (MeSH), as defined by the United States National Library of Medicine (NLM). This list continues the information at List of MeSH codes (G13). Codes following these are found at List of MeSH codes (H01). For other MeSH codes, see List of MeSH codes. The source for this content is the set of 2006 MeSH Trees from the NLM. – genetic structures – base sequence – at rich sequence – gc rich sequence – cpg islands – matrix attachment regions – regulatory sequences, nucleic acid – enhancer elements (genetics) – e-box elements – hiv enhancer – response elements – serum response element – vitamin d response element – insulator elements – locus control region – operator regions (genetics) – promoter regions (genetics) – response elements – serum response element – vitamin d response element – TATA box – regulatory sequences, ribonucleic acid – rna 3' polyadenylation signals – rna splice sites – rna 5' terminal oligopyrimidine sequence – silencer elements, transcriptional – terminator regions (genetics) – repetitive sequences, nucleic acid – interspersed repetitive sequences – dna transposable elements – genomic islands – retroelements – endogenous retroviruses – genes, intracisternal a-particle – long interspersed nucleotide elements – short interspersed nucleotide elements – alu elements – tandem repeat sequences – dna repeat expansion – trinucleotide repeat expansion – dna, satellite – microsatellite repeats – dinucleotide repeats – trinucleotide repeats – trinucleotide repeat expansion – minisatellite repeats – terminal repeat sequences – hiv long terminal repeat – hiv enhancer – chromosome structures – centromere – kinetochores – chromatids – chromatin – euchromatin – heterochromatin – sex chromatin – nucleosomes – nucleolus organizer region – synaptonemal complex – telomere – chromosomes – chromosomes, archaeal – chromosomes, artificial – chromosomes, artificial, bacterial – chromosomes, artificial, mammalian – chromosomes, artificial, human – chromosomes, artificial, p1 bacteriophage – chromosomes, artificial, yeast – chromosomes, bacterial – chromosomes, artificial, bacterial – chromosomes, fungal – chromosomes, artificial, yeast – chromosomes, mammalian – chromosomes, artificial, mammalian – chromosomes, artificial, human – chromosomes, human – chromosomes, artificial, human – chromosomes, human, 1-3 – chromosomes, human, pair 1 – chromosomes, human, pair 2 – chromosomes, human, pair 3 – chromosomes, human, 4-5 – chromosomes, human, pair 4 – chromosomes, human, pair 5 – chromosomes, human, 6-12 and x – chromosomes, human, pair 6 – chromosomes, human, pair 7 – chromosomes,
