Read the following text and answer the following question on the basis of the same:
The term biotechnology refers to the use of living organisms or their products to modify human health and their human environment. For example, ‘testtube’ programme, synthesis of a gene or correcting a defective gene are all part of biotechnology. The basis of modern biotechnology is genetic engineering and maintenance of sterile conditions. Genetic engineering is the technique that alter the chemistry of genetic material i.e. DNA and RNA, then this genetic material is introduced into host organisms, which alter the phenotype of the host organism.

DNA fragments are neutral.

Explanation:
DNA is a double-stranded molecule made up of nucleotides. Each nucleotide consists of a phosphate group, a sugar (deoxyribose), and a nitrogenous base (adenine, thymine, cytosine, or guanine). The sugar-phosphate backbone of DNA is negatively charged due to the presence of phosphate groups. However, the nitrogenous bases are nonpolar and do not have a charge.

- DNA Structure:
- Double-stranded molecule
- Nucleotides: phosphate group, sugar (deoxyribose), nitrogenous base
- Sugar-phosphate backbone: negatively charged
- Nitrogenous bases: nonpolar, no charge

- DNA Fragments and Charge:
- DNA fragments are segments of DNA that have been cut or broken apart.
- When DNA is fragmented, the phosphate groups from the sugar-phosphate backbone remain negatively charged.
- However, the nitrogenous bases within the DNA fragments do not have a charge.
- As a result, the overall charge of DNA fragments is neutral.

- Importance of Charge in DNA Analysis:
- The charge of DNA fragments is important in techniques like gel electrophoresis.
- Gel electrophoresis is a common method used to separate DNA fragments based on their size and charge.
- During gel electrophoresis, an electric field is applied to the gel, causing the negatively charged DNA fragments to move towards the positive electrode.
- The movement of DNA fragments through the gel is influenced by their size and charge.
- Since DNA fragments are neutral, their movement through the gel is primarily determined by their size.

In conclusion, DNA fragments are neutral as they consist of negatively charged phosphate groups in the sugar-phosphate backbone and nonpolar nitrogenous bases. The neutrality of DNA fragments is important in techniques like gel electrophoresis, where their movement is primarily based on size rather than charge.
