Lactic acid is being produced from anaerobic respiration. If compared to cellular respiration, fermentation does not produce much energy.</span>
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from errors during DNA replication or other types of damage to DNA, which then may undergo error-prone repair, or cause an error during other forms of repair, or else may cause an error during replication. Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics of an organism.

During prophase, the chromosomes become visible as paired chromatids and the nuclear envelope disappears
Hope this helps!! :D
