Molecular Biology Unveiled: Careers, Training, and a World of Possibilities

1. Introduction to Molecular biology:

Molecular biology is simply the study of blueprint of life. Scientists can learn more about how life works, changes, and adapts by examining the chemicals that comprise cells and creatures. Molecular biology methods are influencing the future in a variety of ways, from disease diagnosis to crop improvement.

Let's examine the fundamental procedures and methods that characterize molecular biology research and how they advance our knowledge of living things.

2. What is molecular biology and its techniques?

One of the main pillars of contemporary research is molecular biology, which studies the composition and properties of living molecules such as proteins, RNA, and DNA (macromolecules) present in living organisms, including the molecular makeup of genes and their mechanisms of expression, mutation, and replication. It has transformed disciplines like biotechnology, genetics, and medicine by offering strong instruments for examining and working with these molecules. The techniques involved are DNA isolation and quantification, Gel Electrophoresis, QUBIT, PCR, Sanger Sequencing, etc.

1. 1.  DNA Isolation and quantification: The process of separating DNA from an organism's cells from a sample—usually a biological sample like blood, tissue, etc. is known as DNA isolation. To purify the DNA and rid it of other biological components, the cells must be broken open and proteins and other impurities removed. The isolated DNA is then quantified using QUBID.
   2.  Gel Electrophoresis: Gel electrophoresis is a lab technique used to separate proteins, RNA, or DNA based on size. An electric field drives the molecules through a gel with tiny pores. The movement speed is inversely proportional to molecule size, meaning smaller molecules pass through faster than larger ones. This process helps analyse and sort biomolecules effectively.
   3.  QUBIT: Based on the fluorescence intensity of fluorescent dye binding to double-stranded DNA (dsDNA), the Qubit fluorometer measures the amount of DNA. Since Qubit evaluates intact dsDNA, it is typically thought to be helpful for assessing DNA quality prior to next-generation sequencing.
   4.  PCR:  Kary Mullis developed the technique known as the polymerase chain reaction, which uses DNA polymerase to drive repeated cycles of denaturing, annealing, and elongation to produce numerous copies of DNA. Living creatures are not used in the amplification of particular nucleotide sequences. PCR is a rapid, simple, and effective method for amplifying specific DNA segments.
   5.  Sanger Sequencing: Sanger sequencing determines the nucleotide sequence of DNA fragments, typically under 1,000 bp, with 99.99% accuracy. It is the gold standard for confirming sequences, including those from next-generation sequencing. The Human Genome Project used this method to sequence small DNA fragments (900 bp or less), assembling larger fragments and whole chromosomes from these pieces.
