Answer:
D.) The Cell's genetic Material is copied.
Explanation:
In preparation for cell division, the cell makes a replica of its entire DNA. This happens during the S, or synthesis, phase of the cell cycle. Mitosis is the division of one cell into two cells that each has a nucleus and the same amount of DNA as the original cell.

Answer:
Transcription, mRNA (processing, transport, localization and stability), translation.
Explanation:
- Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
- mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
- In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA

Answer:
1. homologous.
2. Meiosis
3. Human sex cells do have 23 chromosomes, but not these 23. ... None, egg cells don't have chromosomes. No, sex cells do have chromosomes. Meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes one homolog of each pair. This is the haploid number.
