Answer:
base substitutions-causes sickle-cell disease
deletions- causes deletion syndrome, cystic fibrosis, Turner syndrome, and Williams syndrome
insertions-it can cause all amino acids in the chain after that point to be different. This results in an entirely different protein than the desired one.
Explanation:
Answer:
1. Restriction enzymes
2. DNA ligase
3. ?
4. ?
5. ?
-------------------------------------------------
1. Identify your gene of interest (the one that produces human insulin in this case).
2. Isolate it from the rest of the DNA via restriction enzymes. Also extract a plasmid from a bacterium.
3. Use the restriction enzymes on the bacterium as well.
4. Join the cut plasmid and your gene of interest via mixing them and with the help of DNA ligase.
5. Insert the recombinant plasmid into a host cell. The plasmids are taken up by the bacterium by transformation.
6. Select for cells that have been transformed by linking the gene of interest to an antibiotic resistance gene or a report gene.
-------------------------------------------------
1. Agricultural Uses, we can insert disease-resistant genes into plants for example
2. We can amplify the DNA found at a crime scene to more easily trace down suspects
3. Medical Uses; we can more easily detect diseases and test for viruses (via amplification of blood samples).
Answer:
The top of the food chain consumes the least amount of energy because producers that are eaten by the first consumers in a food chain only receive about 10% of the energy that the autotrophs have. As you go up the food chain, 90% of the energy that the prey contains is not consumed. This is why the top consumer receives the least amount of energy from autotrophs.
