Answer:
The best possible outcome for the cell in the event of mis-copied mRNA is for the mis-copied sequence to code for the same amino acid as the correct sequence would have done
Explanation: The process of transcription during which the message in DNA is transcribed as genetic codes into mRNA is sometimes not error proof. Synthesized mRNA is usually transported into the cytoplasm where the codes are translated into protein.
Each genetic code which is usually a sequence of 3 purine/pyrimidine bases codes for an amino acid. However, due to the degenerate nature of the genetic codes, more than one codon can code for the same amino acid. The degenerate nature is caused by the fact that there are 64 possible codons and there are 20 amino acids in nature. For example, UUA, UUU and UUG can be coding for the same amino acid in nature.
Hence, if a mistake occur during transcription, the best possible scenario for the cell is that the mis-copied sequence will end up coding for the same amino acid(s) as the correct correct sequence would.

Answer:
The cell has to undergo a process called Osmosis
The absence of apoptosis which is known as cell death. Additionally. there is an excessive production of cells through cell cycle.
The cell cycle is process by which a cell produces a new similar daughter cell. it composes of two main phases These are called the interphase and m-phase. The interphase has three key stages which are gap 1, s phase and gap 2. And the M-phase is where the cell itself divides with an equal number of chromosomes.
Because evolution has not been explicitly proven. There has been some evidence, but there is not enough real proof to support this. Even the man who invented the theory of evolution ended up not believing in his own theory at the time of his death. Overall, the premise of evolution is built on an unstable rock, a theory.
