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:
Breathing out the carbon dioxide
Explanation:
Blood is the medium through which carbon dioxide is transported to the lungs from where it is exhaled out.
The Carbon dioxide produced in cells after respiration diffuses into the blood in exchange of oxygen delivered to the cells for further respiration. Blood while flowing through the lungs passes carbon dioxide to its alveoli which is then exhaled out and oxygen is inhaled from outside.
Hence, cell keep the carbon dioxide from building up in the cytoplasm and poisoning the cell by exhaling CO2.
Pollution can effect the food chain and the food web In many ways. The first of wich is it can kill off animals. A good example of this is marine life.
They both eat zooplankton I think
