Why is the use of embryonic stem cells controversial?

The embryos are destroyed in the process of extracting the stem cells.

People consider their use as destroying a life.

They are taken from little kids, which is painful.

They are put into a different person.

A few days after fertilization, cells in the embryo begin to turn on and off particular genes in order to become particular cell types. This process is called...

Differentiation / Specialization

Why are your muscle cells different from your nerve cells?

muscle and nerve cells have the same DNA (same genes) but different genes are turned on

muscle and nerve cells have different DNA, different genes

muscle and nerve cells began with the same DNA (same genes) but some different genes were destroyed by each cell type

muscle cells are not different from nerve cells, they are the same

Which of the following allows a cell to become specialized?

different patterns of gene expression

location of the cell in the body

function of the cell in the body

different combinations of genes in the nucleus

Which best explains why muscle cells are different from blood cells?

Different genes are activated in muscle cells than in blood cells.

A mutation occurs during the development of muscle cells but not in blood cells.

Muscles cells experience different environmental influences than blood cells.

Muscle cells are produced by the brain, but blood cells are produced by the heart.

How do stem cells know what type of cells to differentiate into?

Signals from chemicals in the organism or from the environment determine which genes will be turned on and off.

The nucleus has instructions to turn some genes on and some genes off.

Genes turn on and off randomly.

The cell has unique DNA that determines what the cell will become.

Which of the following best describes the main function of stem cells in the body?

To replace damaged or lost cells by differentiating into specialized cell types

To transport oxygen throughout the body

What triggers a stem cell to begin the process of specialization?

Signals from surrounding cells and the environment

Which statement is true about the DNA in a skin cell and a nerve cell from the same person?

They have identical DNA, but different genes are expressed

Skin cells have more DNA than nerve cells

They have completely different DNA sequences

What is the primary difference between a stem cell and a fully differentiated cell?

Stem cells can become multiple cell types, while differentiated cells have a specific function

Stem cells have no DNA, while differentiated cells do

Differentiated cells can divide indefinitely, stem cells cannot

Stem cells are only found in plants

During the process of differentiation

only specific sections of DNA sequence are activated to determine the structure and functions of a body cell

all sections of DNA are activated to determine the structure of a body cell

ONLY ONE section of DNA are deactivated to determine the structure of a body cell

The diagram shows how specialized body cells can develop. Which of the following best explains why cells that contain the same genetic material do not develop into the same types of cells?

Because internal and external stimuli can trigger the activation of specific genes in the DNA of cells

Because random mutations can occur in the DNA of cells during early embryonic development

Because messenger RNA is converted to transfer RNA when cell differentiation begins

Because chemical signals that are released during the cell cycle can result in the linking of similar genes
