Answer:
HeLa cells have been used in research to study
Explanation:
the nature and progression of cancer
Outer membrane or plasma membrane, cytoplasm, nucleus, ribosomes,
It must pass from the nucleus to the ribosomes, hope this helped!
<span>Bacterial genome is prone to mutational changes due to its simple nature and less efficient DNA repair mechanisms compared to humans, thus it has more chances of obtaining new genetic traits.</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.
