Molecular Techniques
Molecular techniques are methods employed in molecular biology, genetics, biochemistry, and biophysics to manipulate and analyze nucleic acids (deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)), protein, and lipids. Techniques in molecular biology are employed to investigate the molecular basis for biological activity. These techniques are used to analyze cellular properties, structures, and chemical reactions, with a focus on how certain molecules regulate cellular reactions and growth.
DNA Fingerprinting and Gel Electrophoresis
The genetic makeup of living organisms is shown by a technique known as DNA fingerprinting. The difference is the satellite region of DNA is shown by this process. Alex Jeffreys has invented the process of DNA fingerprinting in 1985. Any biological samples such as blood, hair, saliva, semen can be used for DNA fingerprinting. DNA fingerprinting is also known as DNA profiling or molecular fingerprinting.
Molecular Markers
A known DNA sequence or gene sequence is present on a chromosome, and it is associated with a specific trait or character. It is mainly used as a genetic marker of the molecular marker. The first genetic map was done in a fruit fly, using genes as the first marker. In two categories, molecular markers are classified, classical marker and a DNA marker. A molecular marker is also known as a genetic marker.
DNA Sequencing
The most important feature of DNA (deoxyribonucleic acid) molecules are nucleotide sequences and the identification of genes and their activities. This the reason why scientists have been working to determine the sequences of pieces of DNA covered under the genomic field. The primary objective of the Human Genome Project was to determine the nucleotide sequence of the entire human nuclear genome. DNA sequencing selectively eliminates the introns leading to only exome sequencing that allows proteins coding.

INTRODUCTION
All living things require chemicals known as proteins. They are composed of amino acids and play a variety of roles in the body, including providing structure and catalyzing biochemical reactions. Proteins are found in all cells, tissues, and organs and are composed of long chains of amino acids held together by peptide bonds. The sequence in which the amino acids are arranged determines the protein's structure and function. Proteins can be further divided into two categories: structural proteins and regulatory proteins. Structural proteins provide structure to the cells and tissuesCollagen, actin, and keratin are a few examples of structural proteins. Regulatory proteins, on the other hand, control the activity of other molecules, such as DNA and other proteins, and play an important role in metabolism, cell communication, and other cellular processes. Examples of regulatory proteins include hormones and enzymes.
