This would result in the daughter cells getting different sets of DNA, probably missing certain genes in one or the other daughter cell. During development, both growth and differentiation are important. Define what is meant by these terms. Growth is the process by which the size of a tissue gets bigger. This is through increases in cell number brought about by cell division.
Differentiation is the process by which cells become more specialized.
Explain what is meant by contact inhibition and describe how it relates to cancer cells. Contact inhibition is the cessation of cell growth and division when the cell contacts a neighboring cell. The contact with the neighboring cell actually inhibits continued cell division. Cancer cells do not obey contact inhibition and therefore continue to grow even though they are in contact with other cells - this results in a tumor. Each coding region has a start signal at which the ribosome can bind and initiate protein synthesis.
