There are three main types of mutation present for DNA. They are substitution, insertion and deletion. Substitution is the exchange of one base for another. Insertion happens where extra base pairs are inserted. Deletions are mutations where a section of DNA is lost. Therefore, the correct answer is substitution.
The phase during which sister chromatids aggregate along the equator of the cell is called the metaphase.
The image shows the process of cell division through mitosis. The mother cell divides into two genetically identical daughter cells in mitosis. There are four main phases in the mitosis process. They are: prophase, metaphase, anaphase and telophase. In the metaphase, the highly condensed sister chromatids line up along the equator of the cell by binding to the microtubles that form the skeleton of the cell. These kinetochores line up the chromatids at the equator to initiate their separation.
<span> Decomposition aids farmers, preserves forest health and even helps make biofuels. Decomposers mine them from the dead so that these recycled materials can. Plants use glucose and other sugars to grow and fuel all of their activities, When plants die, carbon and other nutrients stay in their fibers.</span>
