Grollman Method: Study of DNA and its effect on living organisms

The Grollman method, also known as the acetylene method, is a technique for studying DNA and its effects on living organisms. This method was developed by an American physiologist named Albert Grollman in 1946 and has since been widely used in scientific and medical research.

The essence of the method is to use acetylene to modify nucleotides in DNA. Acetylene is incorporated into the DNA molecule in place of thymine (one of the four bases of DNA), resulting in the formation of a specific product that can be detected and identified.

Using this method, scientists can study various aspects of DNA, such as mutations, replication and transcription. It can also be used to study the effects of various factors on DNA, such as radiation and chemicals.

One important application of the Grollman method is its use in medical research. For example, it can help study genetic disorders such as cancer and hereditary diseases, as well as develop new drugs aimed at eliminating these disorders.

In addition, the Grollman method is important in the field of ecology and the environment. It can be used to study the effects of pollution on the DNA of living organisms, which could help develop more effective methods of protecting the environment.

In conclusion, the Grollman method is a powerful tool for studying DNA and its effects on living organisms. It has found wide application in scientific and medical research, as well as in the field of ecology and the environment. Certainly, this method will continue to play an important role in future research in these areas.



The Grollman method is a method for determining the concentration of ammonia in the blood. It was developed by American physiologist Walter Grollman in the 1940s and is widely used in medical practice.

The principle of the method is that ammonia contained in the blood reacts with acetylene to form acetonitrile and water. The concentration of ammonia in the blood is determined by the amount of acetonitrile formed.

The Grollman method is simple and fast, making it convenient for use in clinical practice. It also has high accuracy and sensitivity, which allows you to detect even small deviations from the norm.

One of the main advantages of the Grollman method is its versatility. It can be used for blood testing in both adults and children, as well as in patients with various diseases.

Despite its popularity, Grollman's method has some limitations. For example, it cannot be used if there are large amounts of fatty acids and proteins in the blood, which could interfere with the reaction. Also, the method can give false positive results in the presence of certain medications in the blood, such as penicillin and sulfonamides.

In general, the Grollman method remains one of the most accurate and reliable methods for determining the concentration of ammonia in the blood and continues to be used in medical practice to this day.
