Answer:
Mitosis may be defined as the process of cell division in which a single diploid parent cell divides into two daughter cells. The four stages of mitosis are prophase, metaphase, anaphase and telophase.
The chromosomes get align at metaphase plate during metaphase. Sometimes the arrangement of chromosomes takes more time and after their alignment anaphase process begins because cells has various checkpoints to maintain the proper cell division. Their improper functioning can cause diseases like cancer. The cells has proper metaphase/ anaphase transitions check point that maintains the proper cell division.
Answer:
transcription requires a specific combination of transcription factors
Explanation:
Combinatorial control refers to a regulatory mechanism in eukaryotic transcription that involves several transcriptional factors. Simply saying, in eukaryotes, expression of a gene is controlled by specific combinations of transcriptional factors. This also means that one factor can be involved in regulation of two distinct genes but in combination with different other factors.
Combinatorial control is one of the examples which shows the complexity of gene regulation in eukaryotes over the prokaryotes.
