What evidence suggests that a cell spends the majority of its time in interphase? A. Only a small percentage of cells in a tissu
e or cell culture are seen to be in mitosis at any given time. B. A large percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time. C. A moderate percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time. D. Mitosis is too intricate a process to last very long.
The correct answer is A. "Only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time".
Explanation:
If we were able to analyze at what phase of the cell cycle are most of the cells in our body, we will realize that most of them are at the interphase phase. The interphase phase is characterized by the cells not being in a mitotic stage, and they only are preparing their genetic material for replication. One evidence that suggest the fact that most cells are in interphase phase is that only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time. For this reason, interphase is also known as the "daily living" or metabolic phase of the cell.
A. Only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time.
Explanation:
<em>The evidence that suggests that a cell spends the majority of its time in interphase is the fact that only a small percentage of cells in a tissue or cell culture are seen to be in mitosis at any given time.</em>
If such is not the case, a moderate to a large number of cells in tissue or cell culture should be seen in active mitosis.
<em>Because of the longer nature of interphase when compared to mitosis, more cells are caught in the interphase stage of the cell cycle than the mitotic phase.</em>
Nucleotides are the subunits of DNA. The four nucleotides are adenine, cytosine, guanine and thymine. Each of the four bases has three components, a phosphate group, a deoxyribose sugar and a nitrogen-containing base.
