termination signal造句

• J appears to act as a termination signal for RNA polymerase II.
• One of the structures looked exactly like a rho-independent transcription termination signal.
• Transposition initiates at the 52 end and gene capture occurs if the 32 termination signal is missed.
• The terminator structure is recognised as a termination signal for RNA polymerase and the operon is not transcribed.
• As a random sequence provides the novel termination signal, this model does not require a high density of Helitrons in the genome.
• In 1999, a Global Hawk undergoing tests at Edwards crashed when it inadvertently received a flight-termination signal from a Nevada test range.
• With this understanding, it soon became possible for other investigators to assign each of 61 codons to a specific amino acid and three codons to polypeptide chain termination signals.
• Eukaryotic termination factors bind to the termination signal region and disturb RNA polymerase II as it moves by, causing it to fall off the DNA strand within the next 300 base pairs.
• On March 29, 1999, a Global Hawk was flying over a test range near the China Lake Naval Weapons Center when it inadvertently received a flight termination signal from Nellis Air Force Base in Nevada.
• Excessive copies of the phage genome can be packaged, called " polyphage "; although these are due to improper termination of extrusion about 5 % of the phage produced in the presence of termination signals are twice the normal length.
• This prolonged activity may have to do with impaired function of the basal ganglia, which is thought to send a termination signal to the SMA . While changes in preparatory movement activity are present in PD patients, executed-movement processes in the brain seem to be unaffected, suggesting that premovement activity abnormality may underlie the difficulty in movement prevalent in Parkinson's disease.
