 The concept of biology has undergone a tremendous change during the past few decades. It cannot be studied as an isolated subject. In order to understand life, a fair understanding of the two other natural sciences i.e. chemistry and physics is absolutely essential. 

Apart from these two sciences, other branches of science like computer, electronics etc. have also been complementing the biology for the advancement in the living world. Following is a brief review of the interrelationship of biology with other sciences:

         Biochemistry: The body of living organism is composed of several organic and inorganic compounds. The elements participating in these are not different from those which form nonliving matters.

  •  The chemical reactions going inside the body of living organisms follow the general rules of chemistry.
  •  The biological reactions are affected by change in pH, temperature and pressure just like the non-biological reactions. 

        Biophysics: The movement of several molecules of various substances inside and outside the cell is primarily based on the physical processes like diffusion and osmosis.

  •      Transpiration (loss of water in form of vapours) in plants is comparable to physical phenomenon – evaporation. 
  • The joints and bones work on lever mechanism of physics. 
  • The energy transfer during the various living processes is according to well-known principles of thermodynamics applicable to the non-living world. 

        Bioinformatics: The branch of biology making use of Statistics and Computer Science results into a new field called Bioinformatics. 

  • The primary goal of bioinformatics is to increase the understanding of biological processes.
  •  It involves the application of computing systems and computational solution of techniques, analyzing biological data obtained by experiments, database searching and instrumentation to make novel observations about biological processes. 

        Bionanotechnology: It involves the use of biomolecules as part or as an inspiration for nanotechnological devices. 


  • It can help in several ways like engineering bioartificial organs, controlling biofouling and cell culture, allowing associations between genetic variations and diseases to be uncovered etc

 Genomics_command_line_quiz1 For all projects, you may use your own Unix-based system and, where applicable, ensure that you are running the version of the software specified in the assignments. Alternatively, you may use the VMBox virtual machine environment provided with the course materials. Instructions on how to download and use the environment can be found on the course web site. For the following questions, refer to the class workflow and use the data in the Online materials (‘gencommand_proj1_data.tar.gz’) to answer the questions. Assume you sequenced and assembled the genome of Malus domestica (apple), and performed gene annotation. You then collected samples and ran RNA-seq experiments to determine sets of genes that are expressed in the various tissues. This information was stored, respectively, in the following files: “apple.genome”, “apple.genes”, “apple.condition{A,B,C}”. NOTE: The apple genome and the apple gene annotations for this project were extracted from the Rosace

Introduction to Molecular Biology

 Introduction to Molecular Biology Cells are fundamental building blocks of living organisms. Cells contain a nucleus, mitochondria and chloroplasts, endoplasmic reticulum, ribosomes, vacuoles, etc.  The nucleus is important organelle because it houses chromosomes which include the DNA.  The DNA is in essence a blueprint of the organism as it encodes information needed to synthesize proteins . Molecular biologist s would like to understand how human biology works with the hope to treat diseases like cancer. One can look at simpler organisms such as yeasts to understand how human biology works.  Admittedly, unicellular yeasts are very different from humans who have approximately 1014 cells. However, the DNA is similar across all living organisms. For example, humans share 99% of DNA with chimps. Naturally, we would like to know what information contained in that 1% of DNA is so critical to determine all the distinguishing features of humans,  DNA            DNA stands for deoxyribonucle
