The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.
Answer:
The correct answer is option - e. all of the above are useful traits.
Explanation:
A cloning vector is a small segment of DNA that can be established stably in an individual organism and able to internalize a foreign DNA for cloning purposes. The cloning vector could be taken from different organisms such as plasmid of a bacterium, or DNA from a virus. A cloning vector must possess some characteristics -
The cloning vector must be self-replicating ability in the host cells, it should be small in size with restriction site for the restriction endonuclease enzymes in it. The replication character of the vector should not interfere with the internalized DNA fragment. The presence of marker genes in the vector is also a property that is helpful in identifying of recombinant cells.
Thus, the correct answer is option - e. all of the above are useful traits.
Answer:
It's important to participate in the global economy because there are many benefits to it such as free trade, increased investment, and increased economies of scale. The developments occurring throughout our global economy are crucial because it has allowed for working with other countries to make the most of the good and services, and in turn allowing a strong economy to be formed.
Explanation:
Answer:
B is the correct answer.
Explanation:
Law of conservation of mass states that the mass of an object never changes with time. This means that during a chemical reaction mass of reactants always remains the same even after the formation of products.
We can conclude that the law of conservation of matter states that during a chemical reaction, the amount of matter does not change
