Answer:
<em>The correct options are:</em>
<em>Prior to process 1, DNA should copy itself to allow the cell to divide.</em>
<em>Between processes 1 and 2, the mRNA must be modified before leaving the nucleus.</em>
Explanation:
For eukaryotes, the mRNA is made in the nucleus from the DNA. This process in known as transcription. The process of making proteins from the mRNA takes place in the ribososmes of the cytoplasm. This process is known as translation. The mRNA has to be modified before it is transported for translation. Otherwise, the mRNA will be degraded by the enzymes of the nucleus.
When the organism dies in a moist or wet area the organism gets covered in mud and the mud hardens like a rock.
