Answer:
The correct answer is option d) "Only one of the two fusion proteins possesses a nuclear localization signal".
Explanation:
A nuclear localization signal or sequence (NLS) serves as an amino acidic tag that is recognized by the cell, and the cells responds by importing the protein into the nucleus. In this example a protein was divided into two segments and was used to generate two fusion proteins. Since only one of the two proteins was found in the nucleus, we can conclude that only one of the two fusion proteins possesses a nuclear localization signal.
If a particular cell is known to be round and incapable of producing its own food, such a cell would not be a plant cell. As such, from the options below:
- <em>CENTRAL VACUOLE
</em>
- <em>plasma membrane
</em>
- <em>
cell wall
</em>
- <em>
chloroplast</em>
The correct answer as to which of the organelles the cell must have would be the plasma membrane.
- central vacuole, cell wall, and chloroplast are all characteristic of plant cells.
- All cell types have plasma membrane.
Hence, since it has been established that the cell is not a plant cell, the only organelle left that the cell cannot do without is the plasma membrane.

The assortment of homologous chromosomes during meiosis is random and generates genetic variation, the raw material for evolution.
During metaphase I of meiosis, homologous chromosomes are lined up at the equator plate of the cell in order to be separated (assorted) in anaphase I.
The separation of homologous chromosomes during meiosis I is random. Daughter cells receive unique gene combinations from an original parent cell.
Subsequently, haploid cells got from two successive meiotic divisions fuse during fecundation to form a diploid (2n) zygote.
During prophase I, non-sister chromatids interchange genetic material by a process known as recombination. This genetic process also increases genetic variation in daughter cells.
In conclusion, the assortment of homologous chromosomes during meiosis is random and generates genetic variation.
