Answer:
In one way, the existence of a nonsense mutation would lead to the generation of a premature termination codon that will be identified by the RNA polymerase as a termination sequence encouraged by the activity of Rho factor to dissociate ribosome, thus, discharging RNA polymerase and preventing further transcription mechanism making the transcription of the downstream sequence impossible.
For the second way, there is a need to consider that the mechanism is taking place post-transcriptionally. Thus, the effects should be devised after transcription has taken place and the only fate lies in the mechanism encouraged by the RNA dependent RNA-polymerase. However, for this to take place, the event of genetic recombination can also be taken into account leading to the appearance of the faulty gene in the sequence. Apart from this, the open reading frame is required to be co-expressive that would be the most suitable factor, which determines whether the downstream sequences will be transcribed or not post nonsense mutation.
However, the total change relies upon the fact that the mutation is taking place artificially or is induced naturally. One more thing to consider is that there is an existence of another gene known as MCB 354, which is encrypted by another gene and is probably monitored by another promoter sequence. Thus, co-expression would probably be the mechanism in terms of the rho-dependent termination.
Answer:
Stores nutrients and cellular waste products.
Explanation:
Vacuole is a space that is line with membrane and within the cell that lacks cytoplasm but filled with fluid.
They are important cytoplasmic organelles and perform certain functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.
In plant, large central vacuoles enable them to attain a large size without accumulating the bulk that would make metabolism difficult.
<u>Answer: </u>
Option(D)
Powder Alarm
<u>Explanation: </u>
The powder alarm was a considerably prominent reaction to the orders of General Gage, royal governor to the British soldiers to remove the gunpowders from the magazine.
In response to this action, amid rumours that blood had been shed, alarm scattered to Connecticut and even beyond through the countryside, and American Patriots sprung into action, fearing that war was at hand.
