In eukaryotic cells, the DNA that codes for the cell's proteins is stored in a membrane-bounded organelle called the nucleus.
<h3>What is the nucleus?</h3>
The cell nucleus is an organelle delimited by a membrane where the cellular genetic material organized in DNA molecules together with proteins such as histones is stored. Its function is to keep this genetic material protected and control the expression of DNA, as in the transcription of proteins.
Therefore, we can confirm that In eukaryotic cells, the DNA that codes for the cell's proteins is stored in a membrane-bounded organelle called the nucleus.

Convergent evolution in my understanding is the independent evolution of similar features in species of different lineages.
During the prophase the nucleoli in the nucleus disappear. The chromatin fibers become tightly ccoiled and condense into chromosomes. Chromosomes line up in pairs and are joined at the centromere. In the cytoplasm, the spindle fibers begin to formand are made of microtubules.
Answer:
C. Prohase 1
Explanation:
It is during prophase 1 of meiosis that crossing over occurs before tetrads or homologues pair of chromosomes are alligned across the equator of metaphase 1. In Meiosis 11, only the sister chromatics will be left or remain and the homologues pair of chromosomes would be moved to separate cells.
