Although errors might happen during the transcription or translation process, the fact that amino acids are being coded by a number of different codons would offset the error. This would offset the transcription and translation errors because there are a number of codons present so even though a wrong match or pairing of the letters would happen, another type of codon having those letters would be present which results to not becoming an issue or being a bad type of mutation. It would basically decrease chances of a transcription or a translation process would cause an erroneous type of protein formed.
This is an example of developmental homology. Studying embryological development of living things provides clues to the evolution of present-day organisms. During some stages of development, organisms exhibit ancestral features in whole or incomplete form. Homologous structures are those structures whose underlying similarity arises from their being derived from a common ancestral origin while analogous structure are those whose similarity comes from their performing of a similar function.
<span>An injury to Head/brain can hamper sleep -wake cycle.
other than that injuries to other regions can also hamper the sleep-wake cycle, because the pain could be unbearable resulting in loss of sleep.
So it is also dependent on kind and severity of the injury.</span>
