Google Doodle honors Har Govind Khorana – biochemist who deciphered DNA

In 1968, Khorana was awarded the Nobel Prize in Physiology or Medicine along with fellow scientists Robert W Holley and Marshall W Nirenberg.

Google on Tuesday honored Indian-American scientist Har Gobind Khorana with an illustration on google doodle on the 96th birth anniversary of the noble laureate well known for his work on DNA and the construction of the first synthetic gene.

Born in a village in Raipur of British India in 1922, Khorana was the youngest of five children of a village clerk. He went to the United Kingdom to pursue PhD after the completion of his bachelors and masters degree from Lahore. During his tenure, working under Professor Vladimir Prelog in Zurich for one year, Khorana became an expert on chemical synthesis of nucleic acids and proteins.

Having graduated from the University of Punjab in India in 1945, Khorana later undertook courses at the University of Liverpool and University of Cambridge. The Indo-American scientist began work on his Nobel winning contribution to the field of medicine after he moved to Canada in 1952 and started working at the University of Columbia. Later the Nobel laureate moved to United States and continued his research work at the University of Wisconsin.

At the University of Wisconsin, Khorana worked on his research work with fellow scientists Marshall W Nirenberg and Robert W Holley from 1952 to 1960 was granted American citizenship in 1966. Khorana made his second scientific breakthrough with the construction of the first synthetic gene in 1972 – soon after his fellow scientist Nirenberg discovered the first phase of the genetic code.

In 1968, Khorana was awarded the Nobel Prize in Physiology or Medicine along with Robert W Holley and Marshall W Nirenberg for “their interpretation of the genetic code and its function in protein synthesis”. He was also awarded the National Medal of Science for his iconic work in the field of genetics.

According to the biography of Khorana, he was married to Swiss national Esther Elizabeth Sibler – on whom the biography showered praises for bringing a “consistent sense of purpose … at a time when he felt out of place everywhere and at home nowhere”.

The legendary biochemist passed away on November 9, 2011.

Former West Bengal Assembly deputy speaker and Trinamool Congress leader Asish Banerjee was found dead at a party office next to his residence in Rampurhat, Birbhum district, on Sunday morning.

Police said his body was found hanging and was sent for postmortem. A large crowd gathered outside the Trinamool Congress office after news of his death spread.

Who was Asish Banerjee?

Asish Banerjee had served as the deputy speaker of the West Bengal Assembly when Trinamool Congress chief Mamata Banerjee was the state’s chief minister. He was also a five-time MLA from Rampurhat.

He had served as Bengal’s education and agriculture minister after Mamata Banerjee’s Trinamool Congress first came to power in the state.

Banerjee contested the West Bengal Assembly election earlier this year but lost the Rampurhat seat to BJP’s Dhruba Saha.

Asish Banerjee’s recent party role

Banerjee stepped down as chairman of the Trinamool Congress’s Birbhum district core committee in June. At the time, he said he would continue as a general member of the party.

He lived in the Hattalapara neighbourhood of Rampurhat, with the party office where his body was found located next to his house.

BJP gains in Birbhum

The BJP won six of the 11 Assembly constituencies in Birbhum in the latest state election. This marked a significant change from 2021, when the Trinamool Congress had won 10 seats in the district while the BJP had secured one.

Police have sent Asish Banerjee’s body for postmortem as the circumstances surrounding his death are being investigated.

IPS officer Nupur Prasad, who led the CBI investigation into actor Sushant Singh Rajput’s death, has been recognised with the Medal for Meritorious Service (MSM) this year.

A 2007-batch AGMUT cadre officer, Ms Prasad recently returned to the Delhi Police after completing her tenure with the CBI. She is currently serving as Joint Commissioner of Police in the Economic Offences Wing (EOW), where she oversees investigations involving financial and economic crimes.

The award is part of this year’s recognition for police personnel for distinguished and meritorious service. Such honours recognise contributions in areas including investigation, crime prevention, public service, law and order and administration.

Nupur Prasad’s role in Sushant Singh Rajput case

Ms Prasad came into national focus during the CBI investigation into the death of Sushant Singh Rajput, who was found dead at his Mumbai residence on June 14, 2020.

The case was transferred to the CBI in August 2020 following a complaint by the actor’s family and a legal dispute over jurisdiction.

During her tenure with the agency, Ms Prasad supervised key aspects of the investigation, including the examination of witness statements, forensic evidence and medical records.

In 2025, the CBI filed closure reports, saying its investigation found no evidence of foul play, abetment to suicide or criminal conspiracy in the actor’s death.

Career across Delhi Police, CBI

Ms Prasad has served in several positions during her career, including assignments in the Delhi Police, CBI, Arunachal Pradesh and West Bengal.

Before joining the CBI, she held senior positions in the Delhi Police and became the first Deputy Commissioner of Police (DCP) of Shahdara. During her tenure, she worked on establishing the district’s policing framework following its creation.

She also led operations targeting drug networks and illegal gambling activities while focusing on crime-prevention measures.

Later, as DCP of North Delhi, she oversaw security arrangements for major events, including Independence Day celebrations at the Red Fort and Delhi University elections.

Community-focused policing initiatives

Beyond investigations, Ms Prasad has been associated with community-focused programmes involving women’s self-defence, youth development, cyber safety and drug de-addiction.

During her CBI tenure, she was also associated with several prominent investigations. Media reports have linked her to cases concerning businessman Vijay Mallya and the AgustaWestland helicopter deal.

Current role in Delhi Police

After completing her assignment with the CBI, Ms Prasad returned to the Delhi Police and took charge as Joint Commissioner of Police in the Economic Offences Wing.

The latest recognition adds to her career spanning investigations, policing and public service across several challenging assignments.

Congress president Mallikarjun Kharge and Leader of Opposition in the Lok Sabha Rahul Gandhi skipped the 80th Independence Day celebrations at Delhi’s Red Fort for the second consecutive year.

Prime Minister Narendra Modi led the Independence Day celebrations at the historic venue on Saturday.

The absence of the two senior Congress leaders comes amid strained relations between the ruling party and the Opposition, which further deteriorated during the Monsoon Session of Parliament that concluded on Thursday.

2024 seating controversy

Rahul Gandhi had attended the Independence Day celebrations in 2024 but his seating arrangement triggered a controversy. The Congress leader, who holds the status of a Cabinet minister as Leader of the Opposition in the Lok Sabha, was seated in the second-last row during the ceremony at the Red Fort.

The Opposition had criticised the seating arrangement, calling it an insult to the people. The Defence Ministry, which organised the event, said the arrangement had been modified to accommodate Olympians at the venue.

According to protocol, the Leader of the Opposition is seated in the front row during ceremonial events.

Opposition-ruling party tensions

Relations between the government and the Opposition remained tense during the Monsoon Session, which ended on Thursday.

The session saw repeated clashes between the two sides, with both the Opposition and the ruling party blaming each other for the low productivity of Parliament.

The session began on July 20, with students marching towards Parliament on the first day. Twelve bills were passed during the session, while detailed discussion took place on only one legislation, concerning paper leaks.

The Congress, along with the Trinamool Congress and Samajwadi Party, also boycotted the customary tea party hosted by Lok Sabha Speaker Om Birla after the House was adjourned sine die.
