Cell differentiation is the process by which dividing cells change their function. DNA is essential in gene expression, which gives the ability of cells that are specializing to be able to adequately perform the role they are trying to carry out. It is generally understand that all the cells in our body contain the same DNA, yet they carry out different functions. The key is understanding that specific parts/combinations of the genome are activated which changes the function and shape of the cell. Additionally, if the DNA is damaged or mutated in certain areas of the chromosome, it can cause certain differentiated cells to not function properly.
Explanation:
The Chi Square value for this cross is 0.086. The degrees of freedom is 1 and using a p value of 0.05, it can be proved that there is no significant difference between the observed distribution and the theoretical distribution. Thus, we accept the results.
