Where is the options ???!!!
Answer:
The correct answer is option A. "cell fractionation to study the function of specific organelles".
Explanation:
Cell fractionation is a scientific process used to study the function of specific organelles, which main idea is to fractionate the cells but preserving the individual function of the elements of the cell. Usually, the separation takes place by a centrifugation method. This methodology was developed to identify the location of the organelles within the cells, but nowadays is used to study its functions.
Answer:
A and D
Explanation:
Transfer ribonucleic acid (tRNA) is a type of RNA that decodes mRNA (messenger RNA) into protein. This phenomenon is known as translation.
If the strain of mutant synthetase gene does not grow fast despite having growth characteristics, the following possibilities could happen:
- Sometimes histidine tRNA sends asparagine instead of histidine to other proteins where histidine residue should have been present for growth.
- The normal synthetase might be present but not in an adequate amount.
<span>There is heat from the Earth’s core. Unfortunately, even thought the Earth is round, this heat isn’t evenly distributed. Therefore, sometimes the pressure from the heat in some areas can create currents that move the plates across the Earth’s surface.</span>
Answer:
Radiation leads to mutations that causes genetic drift and decrease fitness.
Explanation:
Radiation is responsible for changing or altering the DNA sequence within a cell.
Radiation either causes mutation or it leads to cell death.
Most of the ionizing radiation causes mutation within the deep inside of our cells which eventually leads genetic drift which means change in the frequency of the allele in a population over time.
Beneficial mutation confer advantage to the organism. But in this case, the mutation is not beneficial and decreases the fitness of the rodent organisms.
