The answer is an enzyme.

When cutting DNA, scientist uses enzymes called restriction enzymes. These enzymes are naturally produced in bacteria as a defense against phages. So, enzymes cut DNA of the phages and thus inactivate it. Also, these enzymes do not cat DNA randomly, but on specific sites. This characteristic of restriction enzymes is used for some molecular biology techniques. All species' DNA contains target sites of restriction enzymes, but most organisms do not have restriction enzymes. Therefore, restriction enzymes are suitable for different techniques.

I can conclude about this microbial agent that it is gram-negative. They are bacteria.

<h3>What are gram-negative bacteria?</h3>

Gram-negative bacteria are a group of microbes that have a thin peptidoglycan cell wall.

Conversely, Gram-positive bacteria have a thick peptidoglycan coating, composed of around 30 layers of peptidoglycans.

The gram-negative bacteria include different microbial agents such as <em>Pseudomonas aeruginosa, Chlamydia trachomatis, Escherichia coli, </em>and <em>Yersinia pestis.</em>

ikadub [295]
Janine is right because CONSUMING TOO MUCH PROTEINS AND NO CARBOHYDRATES WITH PUT MORE PRESSURE ON THE LIVER AND KIDNEY. LIVER AND KIDNEY WILL REQUIRE MORE ENERGY TO BREAKDOWN TOO MUCH PROTEINS. THUS KIDNEY MIGHT GET RUINED DUE TO TOO MUCH WORK.

Carbohydrates, proteins and fats are used as source of energy and converted into energy. Carbohydrates are first to be metabolized for the production of energy. It is readily broken down into simple form. Brain uses only carbohydrate in the form of glucose as energy source. Glucose is used as an immediate fuel.

Protein is used as a source of energy when the body lacks carbohydrates. If protein and carbohydrates are received by the body in sufficient amount, protein is used for other specific purposes. Protein is not reserved for later use and our body do not store protein. It acts as building blocks of body to maintain the proper functioning of the body.

Fats are the last source of energy and used as energy source only in the absence of carbohydrates and proteins. Energy is stored in the body in the form of fat in the adipose tissues for later use in the absence carbohydrates and proteins. This stored fat is broken down into energy during exercise.
