(Continued from previous part...)Oligo
Oligogenic A phenotypic trait produced by two or more genes working together.
Oligonucleotide A molecule usually composed of 25 or fewer nucleotides; used as a DNA synthesis primer.
Oncogene A gene, one or more forms of which is associated with cancer. Many oncogenes are involved, directly or indirectly, in controlling the rate of cell growth.
Open reading frame (ORF) The sequence of DNA or RNA located between the start-code sequence (initiation codon) and the stop-code sequence (termination codon).
Operon A set of genes transcribed under the control of an operator gene.
Optimal Alignment An alignment of two sequences with the highest possible score.
ORF Open reading frame.
Orthologous Homologous sequences in different species that arose from a common ancestral gene during speciation; may or may not be responsible for a similar function.
