Using online simulations to teach biochemistry laboratory content during COVID-19
1Clinical and Health Sciences, University of South Australia and SA Pathology, Adelaide, South Australia, Australia.
Summary
Online simulations and guided laboratory sessions effectively taught essential biochemistry practical skills to diverse undergraduate students when face-to-face teaching was interrupted by COVID-19.
Area of Science:
- Biochemistry education
- Undergraduate science practicals
Background:
- Biochemistry practical courses typically involve hands-on laboratory sessions.
- COVID-19 restrictions necessitated a rapid shift from traditional face-to-face teaching to remote learning.
Purpose of the Study:
- To adapt undergraduate Biochemistry practical content for online delivery.
- To ensure students acquired essential hands-on laboratory skills despite physical distancing measures.
Main Methods:
- Utilized a suite of five online simulations covering core laboratory practices and assays.
- Supplemented online learning with optional, in-person laboratory sessions for kinesthetic skill development once restrictions eased.
Main Results:
- Online simulations successfully taught theoretical and procedural aspects of laboratory practice.
- In-person sessions effectively imparted hands-on skills with instructor guidance.
- Both methods proved highly effective in maintaining practical learning continuity.
Conclusions:
- Online simulations and guided practical sessions are effective strategies for teaching science practicals.
- These adaptable methods can be implemented in various science disciplines facing disruptions to in-person teaching.

Calculating Equilibrium Concentrations
52.2K
Being able to calculate equilibrium concentrations is essential to many areas of science and technology—for example, in the formulation and dosing of pharmaceutical products. After a drug is ingested or injected, it is typically involved in several chemical equilibria that affect its ultimate concentration in the body system of interest. Knowledge of the quantitative aspects of these equilibria is required to compute a dosage amount that will solicit the desired therapeutic effect.

Enzyme-Linked Immunosorbent Assay
17.0K
In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or...

Viral Mutations
39.1K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Enzyme Kinetics
103.0K
Enzymes speed up reactions by lowering the activation energy of the reactants. The speed at which the enzyme turns reactants into products is called the rate of reaction. Several factors impact the rate of reaction, including the number of available reactants. Enzyme kinetics is the study of how an enzyme changes the rate of a reaction.
Scientists typically study enzyme kinetics with a fixed amount of enzyme in the controlled environment of a test tube. When more reactant, or substrate, is...

In-vitro Mutagenesis
15.8K
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
