Many oncogenes are involved, directly or indirectly, in controlling
the rate of cell growth. (ORNL)
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). (ORNL)
Operon
A set of genes transcribed under the control of an operator
gene. (ORNL)
Optimal Alignment
An alignment of two sequences with the highest possible score.
(NCBI)
ORF
Open reading frame. (SMART)
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. (NCBI)
