The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as a plasmid.
Bacteria and certain other microscopic species contain plasmids, which are tiny circular DNA molecules. Physically distinct from chromosomal DNA, plasmids multiply on their own. They normally contain only a few genes, including some linked to antibiotic resistance, and they can spread from one cell to another.
Recombinant DNA techniques are used by scientists to splice the genes they want to research into a plasmid. The inserted gene is duplicated along with the plasmid when it duplicates itself. Molecular cloning, the process of creating DNA molecules and introducing them into a host cell, uses plasmid vectors as the means of delivering recombinant DNA into the host cell.

1. For every action there is an equal and opposite reaction
2. Force = mass times acceleration
3. An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted on by another force.
3. One example is a rock rolling down a hill. You could use a stick or your foot to stop it, but otherwise it would keep rolling
2. An example for law No.2 is pushing a shopping cart. If you push an empty shopping cart, it will go faster than a full shopping cart because the full shopping cart has more mass.
1. One example is a cup on a table. The cup exerts a force down on the table due to gravity, the table exerts an equal and opposite force on the cup to stop it falling through the table
It becomes more alkaline where pH will be more than 8
Answer:
The correct answer will be-False
Explanation:
Calcitonin is a hormone produced by the parafollicular cells present in the thyroid gland.
The Calcitonin plays an important role in the human body as they reduce the level of phosphate and calcium in the blood.
The calcitonin is produced by the C-cells in response to the amount of the calcium levels in the blood as a high concentration of calcium cause release of calcitonin.
Since the calcitonin is involved in the regulation of calcium of blood and not bones therefore, false is the correct answer.
Answer:
Lactic acid fermentation
Explanation:
When sugars are broken down to energy and lactic acid in animal tissues and in microorganisms it is referred to as lactic acid fermentation. Unlike alcoholic fermentation, lactic acid can be further broken down to release the locked up energy should oxygen be made available.
