Gene Expression: How we influence our Genes

Do all cells of the body express the same genes?

• Yes, since they all contain the same DNA

• Yes, since they all make the same proteins

• No, since they don't contain the same DNA

• No, since they don't all need to make the same proteins

What does it mean when we say a gene is "turned off"?

• The gene is no longer working properly.

• The gene cannot be transcribed and translated into a protein

• The gene has a mutation.

• The gene is now activated.

What is gene regulation?

• Mechanisms that turn on and off specific genes to change which proteins are made

• Mechanisms that regulate the replication of DNA

• Mechanisms that regulate which genes get copied

• Mechanisms that turn on and off mitosis in the cell cycle

The signal transduction pathway allows ________.

• one cell to regulate the gene expression of another cell

• a cell to repair damage to its DNA

• genes from one organism to be inserted into the nucleus of another organism's cells

• whole genomes to be sequenced

Life choices can impact what genes get expressed (positively and negatively)

• True

• False
