<span>The detection of chromosomal abnormalities occurs at the G1 stage. This is when the cell has to commit to the process of the rest of the cycle. Thus, if any abnormalities are detected the process can be delayed or stopped entirely.</span>
        
             
        
        
        
Answer:
- Diploid → Prophase, metaphase, and anaphase
- Haploid → Telophase
Explanation:
During prophase I,  chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n 
During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n
During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n   
In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n 
Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.
The two new cells are ready for meiosis II. 
 
        
             
        
        
        
Answer:regulation of RNA processing When a eukaryotic gene is transcribed in the nucleus.
Explanation:
the primary transcript (freshly made RNA molecule) isn't yet considered a messenger RNA. ... The pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus and be translated.
 
        
             
        
        
        
I guess it is euglena because, i<span>t's a plant like protist, it contains chlorophyll and carries out photosynthesis. The eyespots function as a light shield which allows light from a certain direction to strike the light detector.
it doesn' have a cell wall because it is "plant-like," not a plant, 
it has a pellicle that provides strength and flexibility since it lacks a cell wall</span>
