<u><em>Answer:</em></u>
<em>The nucleus and ribosomes both involve messenger RNA (mRNA) during protein synthesis. The mRNA is made during transcription within the nucleus. The mRNA then travels out to the cytoplasm via a nuclear pore of the nucleus.</em>

Answer: Errors that occur during DNA replication lead to mutations, which represent permanent, heritable changes in genetic material. These errors can pass from parent cell to daughter cells and affect many generations of cells.
Explanation:
Cross over is the first way genes are shuffled to give rise to genetic diversity. Cross over takes place in sexual reproduction. The normal way that cross over occurs is chromosomes line up side by side and break off pieces of themselves, then trade those pieces with each other.
If they break the pieces at the same locus in the sequence of base pairs, the result is an exchange of genes called genetic recombination and it ensures that the daughter cells produced have a different genetic makeup from the parent cell and thus diversity occurs.
