long terminal repeats found at the ends of retroviral genomes. Retroviral LTRs contain strong transcriptional regulatory sequence elements (enhancers).
Acronym: ogic runked adio Communications: A method of trunking channel management that gives all users of the system automatic access to all channels, minimizing wait time and making the most efficient use of the available channels. The name is derived from the logic circuitry in the transceivers and repeaters that monitors the system and sends data messages as to which repeaters are free.

long terminal repeats; flank the ends of the HIV genome and contain a Psi-sequence near the 5' end of the RNA-genome
Long terminal repeat. A long DNA sequence that is repeated at each end of retrotransposon and retrovirus DNA.
long terminal repeat, the RNA sequences repeated at both ends of HIV's genetic material. These regulatory switches may help control viral transcription.
long terminal repeat. a segment of the HIV gene that must be activated to "turn on" viral replication.
see long terminal repeat.
Long Terminal Repeat. the genetic material at each end of a genetic sequence. When the HIV genes are integrated into a cell's own GENOME, the LTR interacts with cellular and viral factors to initiate the transcription of the HIV DNA into an RNA form that is packaged in new VIRUS particles. Activation of the LTR is a major step in triggering HIV replication.
long terminal repeat; the longer, more complex repeated sequences at the ends of some mobile elements, which are required for them to transpose. Return to text.
LONG TERMINAL REPEAT. Genetic material at the beginning of the HIV genome that helps control replication.
