B.Sc Chemistry, M.Sc. Biochemistry

Susha is a scientific communication professional holding a Master's degree in Biochemistry, with expertise in Microbiology, Physiology, Biotechnology, and Nutrition. After a two-year tenure as a lecturer from 2000 to 2002, where she mentored undergraduates studying Biochemistry, she transitioned into editorial roles within scientific publishing. She has accumulated nearly two decades of experience in medical communication, assuming diverse roles in research, writing, editing, and editorial management.

Passionate about health and nutrition, Susha is interested in various diet types, such as veganism, and their impact on the body and metabolism. She remains dedicated to staying current with the latest developments in the medical and health science fields. In her leisure time, she engages in gardening, cooking/baking, and sketching/painting. When not immersed in work, she can often be found tending to her garden (weather permitting) or engrossed in her sketching and painting projects.

Structure of DNA

The discovery of DNA structure by James Watson and Francis Crick in the year 1953 is one of the most revolutionary scientific discoveries to date. However, the research leading to the discovery of nucleic acid structure started several years previously and involved many different researchers across the world.

What is the RNA World Hypothesis?

The RNA World Hypothesis is a concept put forth in the 1960s by Carl Woese, Francis Crick and Leslie Orgel. It proposes that earlier life forms may have used RNA alone for the storage of genetic material.

Prokaryotes

Prokaryotes were the first kind of organisms to evolve. They are single-celled organisms that don’t have a well-defined nucleus and also lack other membrane-bound organelles such as mitochondria. The genetic material in prokaryotic cells exists within an irregularly shaped area of the cell known as the nucleoid.

What is the Genetic Code?

The genetic code is a set of instructions that direct the translation of DNA into 20 amino acids, the basic units of proteins in living cells. The genetic code is made up of codons, which are three-letter chains of nucleotides. Each codon codes for one specific amino acid.

Protein Folding

Protein folding is a process by which a polypeptide chain folds to become a biologically active protein in its native 3D structure. Protein structure is crucial to its function. Folded proteins are held together by various molecular interactions.

The 1968 Nobel Prize in Medicine

The 1968 Nobel Prize in Medicine was awarded jointly to Marshall W. Nirenberg, Har Gobind Khorana, and Robert W. Holley. These scientists were recognized "for their interpretation of the genetic code and its function in protein synthesis."

RNA Codons and DNA Codons

The genetic code is made up of a total of 64 base triplets or codons. At least one codon encodes the information for each of the 20 amino acids used in the synthesis of proteins during translation. While one codon can code for only one amino acid, more than one codon can code for the same amino acid, which is described as the degeneracy of the code. The majority of amino acids are encoded for by more than one codon.

Histone Modification

Histones are proteins that condense and package DNA neatly into chromosomes. Modifications to these proteins affect different processes in the cell such as the activation/inactivation of transcription, chromosome packaging, DNA damage and DNA repair.

Epigenetics and Epigenomics

Epigenetics is the study of chemical reactions that influence gene expression, through activation or deactivation of genes at specific times and locations. These changes in gene expression do not involve a change in the DNA sequence, meaning there is a change in phenotype, without any change in genotype.
