Answer:
option A
Explanation:
In carrying out these experimental procedure, the same restriction enzyme that is used to cut out the gene of interest should also be the same used for the cutting of the plasmid to generate sticky ends. Then the desired gene is inserted into the cut plasmid then treatment with DNA ligase. Purified DNA ligase is utilized in gene cloning to join/ligate DNA molecules together forming a recombinant DNA. Thus, step 3 should be carried out after step 4.

The answer is that both produce carbohydrates and water.
Plants to do it in a process called photosynthesis, and they produce oxygen as well and sulfur bacteria do it in a process called chemo-synthesis, and they produce sulfur apart from carbohydrates and water.
The answer for the above question is the Avascular Necrosis. It occurs as an interruption in the blood flow within the bone resulting in the death of the hematopoietic cells, osteocytes, and marrow fat cells making up the bony structure. It is also called osteonecrosis or ischemic bone necrosis, which occurs when there is loss of blood to the bone, since the bone is a living tissue that needs blood, this interruption of blood supply will result to the death of the bone.
