nucleic acid sequence
succession of letters that indicate the order of nucleotides within a DNA (using GACT) or RNA (GACU) molecule
codon
sequence of nucleotide triplets that specifies which amino acid will be added next during protein synthesis;codon consists of three nucleotides, usually corresponding to a single amino acid
anticodon
unit made up of three nucleotides that correspond to the three bases of the codon on the mRNA
gene
basic physical and functional unit of heredity
Hybridization probe
A piece of DNA or RNA that is radioactively or fluorescently labeled for diagnostic tests.
endogenous viral element
virus-derived DNA sequences in an organism's germline genome
short interspersed nuclear elements
type of nucleic acid sequence
mobile genetic element
DNA sequence whose position in the genome is variable
scaffold/matrix attachment region
region of chromatin or DNA that binds to the nuclear matrix
internal ribosome entry site
sequence in the 5′ UTR of some mRNAs where a ribosome can bind
primer
short strand of RNA or DNA that serves as a starting point for DNA synthesis
intergenic region
in genetics, a stretch of DNA sequences located between genes
