Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time. Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation. Often cells can recognize any potentially mutation-causing damage and repair it before it becomes a fixed mutation.

Mutations contribute to genetic variation within species. Mutations can also be inherited, particularly if they have a positive effect. For example, the disorder sickle cell anaemia is caused by a mutation in the gene that instructs the building of a protein called hemoglobin. This causes the red blood cells to become an abnormal, rigid, sickle shape. However, in African populations, having this mutation also protects against malaria.

However, mutation can also disrupt normal gene activity and cause diseases, like cancer. Cancer is the most common human genetic disease; it is caused by mutations occurring in a number of growth-controlling genes. Sometimes faulty, cancer-causing genes can exist from birth, increasing a person’s chance of getting cancer.

One oak tree cell with 14 chromosomes undergoes meiosis. How many cells will result from this process, and what is the chromosom
Alchen [17]

Answer:

The correct answer is - 4 and 7 chromosomes in each cell.

Explanation:

Meiosis is the cell division in which one parent cell produces four daughter cells with a half number of the chromosome than parent cells.

According to the question oak cell performed meiosis which is reduction division so the number of cell will be four and 7 chromosome will be present in each daughter oak cell.

Thus, the correct answer is - 4 and 7 number of chromosome in each.
