Ivan

Eukaryotic transcripts (mRNA) have to undergo capping and splicing before it can be translated.

<h3>RNA processing:</h3>

1. An RNA transcript is first produced in a eukaryotic cell as a pre-mRNA, which needs to be converted into a messenger RNA (mRNA).

2. The RNA transcript is given a 5' cap at the start and a 3' poly-A tail at the end.

3. The process of splicing involves cutting out some RNA transcript segments (introns), then joining the remaining segments (exons) back together.

4. Some genes have the ability to alternate splices, which produces various mature mRNA molecules from the same beginning transcript.

The introns not only do not contain the information necessary to construct a protein, but they also need to be cut off in order for the mRNA to create a protein with the correct sequence. An mRNA with extra "junk" in it will be created if the spliceosome fails to remove an intron, and the translation process will result in the production of the incorrect protein.

The key difference between sexual and natural selection is that natural selection acts on traits which increase fitness, whereas
Rom4ik [11]
Sexual selection example; The brightness of the feathers of a peacock. You may also see similar traits in other birds, where some dance and show off bright feathers to attract a mate, where other build nests. These specific traits do not increase their chance of survival, and are not learned. They increase their fitness because they increase their chances of reproduction and passing on their genes. 

Survival of the fittest = Survival of those who survive, and reproduce

Mitochondrial inner membrane fragments that contain ATP synthase can be isolated in the lab. Under appropriate conditions, these
Neporo4naja [7]

Answer:

The optimum pH of ATP synthase is 6.4 therefore maximum activity  will  occur at pH7  by the vesicle, however because the concentration of the  three , is relatively the same , and exhibited  equal effects  on  the pH,  catalysis  by the vesicle will  not take place BECAUSE NO  HYDROGEN ION IS AVAILABLE  to supply the energy

Generally the synthase activity decreases with drops in pH. The lower pH  of 6.5 from the  set point value , will affect catalysis.

The low pH     lead to  increase in  concentration of base in  the buffer solution. Therefore more H +  are produced .for the synthesis of ATP. The  vesicle catalyzed ATP production.  But the increase in hydrogen ion concentration with time  affect the 3 dimensional structure of the ATPase synthase enzyme in the vesicle and increases the inhibitory effect of ADP therefore  the  vesicle stops the catalysis.
