Zoom Relief: 嘿嘿视频 vs. Cardiff in COVID-19 Quiz

In a bit of pandemic relief, while still extending our knowledge of the coronavirus, students from 嘿嘿视频 and Cardiff University, Wales, will face off in a biochemistry quiz Wednesday (March 10).

  • WHAT: Eric Conn Biochemistry Quizzes, Final Rounds, 嘿嘿视频 vs. Cardiff University
  • WHEN: 11 a.m. PST March 10 (7 p.m. GMT at Cardiff)
  • WHERE: Online
  • ADMISSION: Free

Chancellor Gary S. May will deliver live welcome remarks for the friendly rivalry, and Cardiff President Colin Riordan will deliver a message by video. The event on Zoom is scheduled to start at 11 a.m., and everyone is invited to attend, free of charge.

Distinguished Professor Walter Leal of the Department of Molecular and Cellular Biology is the organizer and the moderator of the Eric Conn Biochemistry Quizzes, named after the .

鈥淚 thought the quizzes would help students get out of the Zoom routine,鈥 said Leal, citing the side effects of screen-time fatigue and a lessening of the ability to focus. He also saw an opportunity to foster international connections at a time when student exchanges have been curtailed.

鈥淲e hope that this educational activity will promote physically distant, socially close interactions between undergraduate students and further our institutions鈥 ties,鈥 he said.

Leal described the response to the quizzes as overwhelming. 鈥淪tudents showed a genuine interest in the activity,鈥 he said. 鈥淭hey recorded videos for self-introduction, studied for the quizzes, and 鈥 more importantly 鈥 made new friends.鈥

The preliminaries

Sixty students signed up for the 嘿嘿视频 preliminary round, so many that Leal divided it into two rounds for a total of 12 teams with five students each. Eight teams competed in the first preliminary, a Feb. 20 Zoom event that drew an audience of more than 350 people. , and see some of the questions at the bottom of this article.

Two teams advanced to the final rounds:

  • Ironic Bonds Team 鈥 Kelly Brandt, Jiaying Liu, Aly Lodigiani, Catherine Rodriguez and Efrain Vasquez Santos
  • Gibbs Team 鈥 Tina Luu, Brandon Matsumoto, Yasi Parsa, Esha Urs and Kathryn Vallejo

The other four teams competed in the second preliminary 鈥 and two of them tied for first place:

  • Alpha Helices 鈥 Mary Aina, Daniel Colon, Stephanie Matsumoto, Joseph Morrison and Eva Pak
  • Beta Strands 鈥 Beatrice Ark-Majiyagbe, Erica Arsaga, Brycen Carter, Shiwani KC and Samantha Levy

鈥淚 am absolutely delighted to provide this opportunity for our students to learn biochemistry, have fun, work as teams and build international ties,鈥 said Leal, who noted that the teams are exchanging university hoodies.

鈥淵es, remote learning is challenging,鈥 he said, 鈥渂ut it also creates new opportunities.鈥 Indeed, besides the biochemistry quizzes, Leal also has organized and moderated three COVID-19 symposia, each of them reaching hundreds of people on Facebook and Zoom.

The finals

Wednesday鈥檚 competition will begin with Ionic Bonds vs. Gibbs Team; the winner will send all five members to the final match, accompanied by one member each from Alpha Helices and Beta Strands, who will compete in a tie-breaker after the Ionic Bonds vs. Gibbs Team match.

The seven-person 嘿嘿视频 team will go up against a seven-person Cardiff team for the championship.

Questions during the finals will focus on protein structures, particularly two proteins closely related to SARS-CoV-2, which causes COVID-19 illness. 鈥淪pecifically,鈥 Leal said, 鈥渟tudents will be asked questions about the structures of human hemoglobin 鈥 the protein that carries oxygen from the lungs to the body鈥檚 tissues (and returns carbon dioxide), and the virus鈥檚 spike protein 鈥 that binds to a human receptor, known as ACE2, and starts the process of invading human cells.鈥

Leal said one of the most notorious presentations of COVID-19 is hypoxia (insufficient oxygen in the blood). 鈥淲hile the virus replicates and the spike proteins trigger invasion to other cells, hemoglobin cannot capture enough oxygen because the lungs鈥 alveoli are filled with the mucus derived from the viral infection,鈥 he said.

Judges: Charles Gasser and Clark Lagarias of the 嘿嘿视频 Department of Molecular and Cellular Biology, and John Harwood and Dafydd Jones of the School of Biosciences, Cardiff University.

Continued outreach: Professor Leal has arranged to have Dean Blumberg, an epidemiologist who is chief of pediatric infectious diseases at 嘿嘿视频 Children鈥檚 Hospital, answer questions about COVID-19 vaccines and vaccinations, while teams are answering their quiz questions during the final round.

Test your knowledge

Here are some of the questions from the 嘿嘿视频 preliminaries (click each question to see the answer):

  • Why do hairdressers use thioglycolic acid for permanent hair treatment?
  • To break disulfide bridges.
  • Why is the spike protein called a glycoprotein?
  • Because it is decorated with sugar.
  • When you get ivy poisoning, where do you expect that the active ingredient (urushiol) will accumulate?
  • In the cell membrane.
  • Who was the scientist at the 嘿嘿视频 Genome Center who came up with the idea of using papain protease to reduce saliva viscosity?
  • Lutz Froenicke
