Question

Express your opinion about the use of DNA fingerprinting.

Answer 1

DNA known as deoxyribonucleic acid is the major component in the cell. It resides in a compact structure called chromosomes. DNA are helical structured single and also double stranded structures in cells. They have a variety of proteins like histone proteins. DNA contains the most vital thing called genes. Numerous genes are termed to be one DNA. Million copies of genes. Genes are the heredity of animals. They contain the genetic information by which animals or organisms have different characters, morphological features.

Complete Explanation:
As we discussed, DNA is present inside cells in a coiled form. Numerous DNA possesses to be chromosomes. It is like a gene bank in a cell. The coils of DNA in the nucleus are nothing but as we knew, chromosomes. They are long stretches of DNA present in a compact manner together by proteins. So, the number of DNA coils present in the body is $1.75$.
In a criminal investigation, DNA fingerprinting is a technique for establishing a relationship between evidence and a suspect. When a DNA sample from a crime scene is compared to a DNA sample from a suspect, and the two DNA profiles match, the evidence is assumed to have come from that suspect.
DNA fingerprinting is a chemical test that shows the gene makeup of a person or other living things. It’s used as evidence in courts to identify bodies, track down blood relatives and to look for cures for disease. It is called DNA fingerprinting because DNA has a unique genetic makeup.

Note:
As we know how DNA gives rise to RNA by transcription. It is the major genetic process to build the genetic information which is RNA and also DNA. It is the process of transcription DNA to RNA, particularly messenger RNA. It uses the DNA as template strand or parent strand and then the RNA is synthesized. DNA fingerprinting is only used for detection of certain or any kind of purposes.
