hello Kiran, 

Biotechnologists develop products from living systems. Biotechnology commonly refers to genetically derived materials, but can also refer to developments based in microbiology, molecular biology and cell biology. Biotechnologists work within several different industries including agriculture, food manufacturing, healthcare and pharmaceuticals.

Biotechnology professionals may specialize in one or more subfields. Specialties include genomics, the comparative study of gene structures; proteomics, which is the study of protein structures; and bioinformatics, which combines biology, computer science and information technology. Products developed by biotechnologists include high-yield crops, disease-resistant farm animals, gene therapy treatments, drugs and biofuels.

biotechnologists design research studies, analyze data and develop procedures. For example, a scientist using recombinant DNA technology must choose the best method to insert foreign DNA into an organism, which can trigger development of new proteins or create an organism with more desirable characteristics.

So there is very small chance of using coding in biotechnology. While studying, you won't be studying coding.

hope you understand well!
