Mysore A. Viswamitra

Mysore A. Viswamitra is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mysore A. Viswamitra rather than just read about it. In short: Mysore Ananthamurthy Viswamitra (14 November 1932 – 10 April 2001) was an Indian molecular biophysicist and crystallographer, known for his pioneering work on the X-ray structural studies of DNA fragments and nucleotide coenzyme molecules. His work is reported to have assisted in the development of the concept of sequence-dependent oligonucleotide conformation.

Key takeaways

  • Mysore A. Viswamitra belongs to chemistry; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Mysore A. Viswamitra to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Mysore A. Viswamitra from memory before moving on to harder problems.

Reference excerpt

Mysore Ananthamurthy Viswamitra (14 November 1932 – 10 April 2001) was an Indian molecular biophysicist and crystallographer, known for his pioneering work on the X-ray structural studies of DNA fragments and nucleotide coenzyme molecules. His work is reported to have assisted in the development of the concept of sequence-dependent oligonucleotide conformation. He was an INSA senior scientist and an MSIL chair professor of physics at the Indian Institute of Science and a visiting professor at the University of Cambridge.

Biography Born on 14 November 1932, in Shimoga, in the south Indian state of Karnataka, Viswamitra did his early education at the University of Mysore and Banaras Hindu University before securing a PhD from the Indian Institute of Science (IISc) and joined IISc in 1954. He served IISc till his superannuation in 1993 during which time he founded the School of Biocrystallography and the Bioinformatics Centre at the institution. He is reported to have determined the structure of a number of mononucleotides for the first time and, along with Olga Kennard, elucidated the oligonucleotide dp(AT)2 structure leading to the first atomic detail view of a DNA duplex. His studies have been documented by way of a number of articles and ResearchGate, an online repository of scientific articles has listed 141 of them. Viswamitra was an elected fellow of all the three major Indian science academies viz. the Indian Academy of Sciences, the Indian National Science Academy, and the National Academy of Sciences, India, as well as the World Academy of Sciences (TWAS). He was a recipient of a number of awards which included C. V. Raman Award of the Acoustical Society of India (1982), J. C. Bose Award of the University Grants Commission of India (1984), TWAS Prize (1986), J. C. Bose Medal of the INSA (1986), R.D. Birla National Award (1988), FICCI Award (1991), S. S. Bhatnagar Medal of the Indian National Science Academy (1993), National Citizens Award (1998) and the Distinguished Alumni Award of the Indian Institute of Science (1999). Viswamitra died, succumbing to a heart attack, on 10 April 2001, at the age of 68, survived by his wife and son. The death occurred immediately after he delivered a public speech at the condolence meeting of his colleague, G. N. Ramachandran.

Worked examples

Example 1 — a first encounter with Mysore A. Viswamitra

Start with the simplest possible case. Write down what Mysore A. Viswamitra claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mysore A. Viswamitra before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mysore A. Viswamitra ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mysore A. Viswamitra

In research
Mysore A. Viswamitra appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Mysore A. Viswamitra in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Mysore A. Viswamitra is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1932 births, 2001 deaths, Academic staff of the Indian Institute of Science, so understanding it makes those chapters shorter.
In everyday life
Look for Mysore A. Viswamitra outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
