Biology

Romashka-Z-Leto [24]3 years ago

In contrast to DNA damage, a mutation is a change in the base sequence of the DNA. A mutation cannot be recognized by enzymes once the base change is present in both DNA strands, and thus a mutation cannot be repaired. At the cellular level, mutations can cause alterations in protein function and regulation

3. Were there any stages of the cell cycle that you did not observe? How can you explain this using evidence from the cell cycle
mario62 [17]

Answer:

The surface area of the cell increases to volume ratio

Explanation:

As a cell grows, the surface area of the cell increases to volume ratio. When cell division occurs, the surface area is distributed and each daughter cell have less surface area but with the passage of time, the surface area increases. The main function of mitosis is to increase the population of the cell, the cell must be divided into two daughter cells in the process of mitosis. Tumors occurs when the process of mitosis is uncontrollable. One observation that is found interesting while looking at the onion root tip cells is the multiplication of the cells by the process of mitosis.
