a. The entire collection of genetic information in the cell is called the genome. b. From neurons to cells embedded deep within our bones, all of the body's cells have the same set of instructions, but each of the cell types is specialized to carry a specific set of instructions. c. Specialization occurs during development when the cells start to activate certain sets of genetic instructions and turn on others. d. The genetic instructions are made of the information-storing organic material called DNA.

Geneticists have found that mouse cells contain 40 chromosomes. Given this information, which of the following statements is true? a) As the mouse grows, new cells will contain 20 identical chromosomes, which will then double to create 40 identical chromosomes before dividing again. b) Muscle cells, lung cells, liver cells, and pancreatic cells will contain different genetic information and chromosome numbers, specialized to their cellular structure and function. c) Chromosomes are grouped into identical matching pairs. These pairs separate during mitosis, meaning each identical daughter cell inherits 20 chromosomes from the parent cell. d) When the mouse cells undergo mitosis, each parent cell will have a total of 80 chromatids at the start of the M phase, and 40 of those will be passed to each daughter cell, creating identical offspring.

The human body constituted by 11 systems, 80 organs and 4 tissues which are populated by over 200 different cell-types. How is it that these 200 differentiated cell-types arise from cells that all share identical DNA molecules in the nucleus? a) actually not all cells in the human body contain the same genomic DNA content. b) even though every cell in the human body contains the same genomic DNA content, each differentiated cell-type translates only a subset of mRNAs. c) even though every cell in the human body contains the same genomic DNA content, each singular cell-type expresses only a subset of the full gene complement. d) even though every cell in the human body contains the same genomic DNA content, each differentiated cell-type builds its own specific protein repertoire by a post-translational mechanism.
