When researchers examine these damaged nerves, they find that the myelin insulation is often gone and the axons are destroyed. These changes prevent nerves from transmitting messages properly.
A
Answer:
No, there are multiple ways in which different mutations in the same gene can cause the same phenotype
Explanation:
Several different mechanisms of mutation can lead to the same phenotype. For example, lets say our phenotype is that flies have white eyes, and we know that this occurs in one particular gene that normally makes the eye colour red. (the red gene)
These mutations likely rendered the red gene ineffective (as the eyes are not red). However, this could happen in a variety of ways.
- There could be a single base deletion in the first exon of the mRNA, changing the reading frame of the protein and messing up the entire sequence (a frame shift mutations)
- The entire gene could be deleted
- A single base could be substituted in an important site of the gene, for example, one which translates into a catalytic residue or binding site in the protein
- There could be an inversion at the promoter region of the gene, such that a transcription factor can no longer bind to transcribe the gene.
There are countless other ways in which a mutation could have been caused. Therefore, just because we know the same gene is affected does not mean that we can assume the mutations are identical.
Cambodia is among the most poorest country economically and socially
The disadvantages of development in places like Cambodia because
<span> People living in poverty often lose their homes for the sake of developmenten
</span>because people loses their home and get even more poorer and loses their last wealth which is their homes
so i conclude correct option is B
hope it helps
I believe the answer would be centrosome. not too sure but hope this helps. :)
