Answer:
B. Premature stop codon mutation
Explanation:
Answer:
A to N
Explanation:
Glutamine is an amino acid with a polar, uncharged side chain. The mutation to alanine, an amino acid with a non-polar side chain, completely affects the enzymatic activity. This makes sense considering the difference in the nature of both amino acids.
To restore the wild-type level of activity the alanine would have to mutate to another polar uncharged amino acid. Among the given options, only Asparagine (N) has a similar chemistry to Glutamine.
Answer:
The correct answer would be -
Remains the same: proton pumping rate, electron transport rate, rate of oxygen uptake.
Decreases or goes to zero: rate of ATP synthesis, size of protein gradient
Explanation:
An H+ channel forms and the membrane becomes very permeable to protons if the protein gramicidin is integrated into a membrane. If gramicidin is added to an actively respiring muscle cell, it will affect the in the following manner:
Remains the same:
proton pumping rate, electron transport rate, rate of oxygen uptake.
Decreases:
rate of ATP synthesis, size of protein gradient
None of these will show an increase due to the addition of gramicidin tlo actively respiring muscle cells.
Answer:
A. The sun
Explanation:
The sun, because there has been theory’s of the sun being able to heat earth from there being a lot of iron in the middle of earth
