Question

match the words in the left column to the appropriate blanks in the sentences on the right. gene expression cancer rna splicing operons therapeutic cloning reproductive cloning all organisms must regulate by turning genes on and off in different cells at different times. in prokaryotic cells, related genes may be organized into, which can be turned on and off as a single unit. eukaryotes have more complex modes of control, including the packing of chromosomes, (which can produce several mrnas from a single gene), and the control of translation. an understanding of gene regulation mechanisms has led to several interesting and important applications. for example, the loss of gene regulation can result in, or out - of - control cell growth. and can produce new live individuals, while can produce potentially therapeutic stem cells.

Explanation:

• Gene expression: All organisms regulate how genes are used (expressed) by turning them on/off.
• Operons: Prokaryotic related genes are in operons (units).
• RNA splicing: Eukaryotes have RNA splicing (produces multiple mRNAs from one gene).
• Cancer: Loss of gene regulation can cause cancer (uncontrolled cell growth).
• Reproductive cloning: Reproductive cloning makes new individuals.
• Therapeutic cloning: Therapeutic cloning makes stem cells.

Answer:

1. gene expression
2. operons
3. RNA splicing
4. cancer
5. reproductive cloning
6. therapeutic cloning
