The answer is C, prophase. this is because when the DNA is copied it "condenses" into chromosomes which is called prophase so yeah :)
Certain enzymes will splice out only the target gene and different enzymes will cut DNA at different locations.
<u>Explanation:</u>
Removing or inserting defective genes and replacing the defective one with the normal one is one of the genetic engineering technique that helps in curing the disease and improving the health status.
When inserting or removing any defective gene, we have to be careful in using the enzymes that would help in splicing out only the targeted gene. If wrong enzymes are used there are chances that it may cut out the normal gene.
Initially, the gene that has to be modified or removed or inserted is chosen and then it is isolated in a matching vector. Finally, it is inserted or removed from the host cell.
Answer:
Ocean desalination, Using nuclear fusion as an energy source and using stem cell technology to cure disease.
Explanation:
Ocean desalination is the major problem that occurs due to removing of nutrients that is present in the ocean water because of human activities. These nutrients are essential for the marine animals so for solving this problem, we should use other alternative energy resources in order to reduce ocean desalination. Using nuclear fusion as an energy source is a good idea but it can't be implemented on the earth because it requires 100 million degrees Celsius which is impossible to generate. Using stem cell technology to cure disease is a great idea which can cure many diseases in the human body. This available technology is used by replacing damaged cells with the healthy cells.
Hi there!
There are 5 prezygotic isolating mechanisms. These are...Mechanical Isolation, Temporal Isolation, Behavioral Isolation, Habitat Isolation, and Gametic Isolation. You may also see Geographical Isolation, Ecological Isolation, or even Time.
ANSWER:
Look at your options and choose the one that I HAVE NOT listed.
Hope this helps!! :)
