Bacteriophage T4: Recombination Assay
Просмотров 97Месяц назад
This video discusses recombination assays with bacteriophages, addressing the challenge of their haploid nature by aiming for recombination between 2 different replicase mutants within a single bacterium. The frequency of recombination is calculated based on the ratio of recombinant to total progeny, with Seymour Benzer's work highlighting the importance of bacterial strain differences in detec...
Correspondence Between One Gene and One Protein
Просмотров 65Месяц назад
It is widely accepted that there is a functional correspondence between a gene and a protein. The study of hereditary diseases like alkaptonuria and phenylketonuria, along with auxotrophic mutants in Neurospora crassa, provides evidence to support the one gene-one protein hypothesis. This evidence reveals a direct correlation between gene mutations and the synthesis of inactive enzymes, which u...
Integrating Inclusive Teaching Strategies into STEM Classrooms
Просмотров 35Месяц назад
In this webinar, we discuss the latest content from LabXchange’s RDEISE project, Advancing Equity in STEM through Inclusive Teaching. STEM educators must be equipped with inclusive teaching strategies in order to foster diversity and create a culture of inclusion in science. LabXchange Outreach & Communications Manager Ilyana Sawka is joined by LabXchange Teachers in Residence Fayola Garner and...
Chromosomes are Linear Arrays of Genes
Просмотров 86Месяц назад
We’ll demonstrate that chromosomes are linear arrays of genes, using genetic studies on Drosophila melanogaster (fruit fly) that were conducted by Thomas Morgan and his research group. The experiments reveal that genes on the same chromosome are linked, and that the second law of Mendel, related to independent segregation, does not hold true for traits that are associated with the same chromoso...
How to: Measure Fruit Fly Chemotaxis Using a Choice Chamber
Просмотров 67Месяц назад
Molly takes us into the lab to measure the chemotaxis response in fruit flies by using a choice chamber and various household substances. Molly also shows us how to analyze the results using a chi-square test. View this video (and more like it) on LabXchange: www.labxchange.org/library/items/lb:LabXchange:6368f6cc:video:1
The Role of DNA
Просмотров 84Месяц назад
DNA is the carrier of genetic information. In this animation, we introduce how pneumococcus transformation and bacteriophage experiments provide key evidence for this. Griffith’s findings demonstrate the transformation of nonpathogenic pneumococcus into pathogenic forms, later identified as DNA. Further experiments by Avery, McLeod, and McCarty, and by Hershey and Chase, confirm DNA’s role in d...
Bacteriophage T4: Plaque Assay
Просмотров 305Месяц назад
This video explores the importance of model systems in understanding the structure of genes. It contrasts historical examples like Mendel's use of pea plants and Morgan's use of Drosophila with the modern approach of using bacteriophage T4. The video demonstrates how to quantify bacteriophage concentrations through dilution series and calculate the titer, essential for genetic mapping and under...
Why Should We Care about Addressing Racism in STEM Education?
Просмотров 37Месяц назад
The underrepresentation of Black, Hispanic, and Indigenous people in STEM is a problem for a variety of reasons. In this video, explore some issues that arise from the lack of diversity in STEM and examine how educators can help to address these issues in high school classrooms.

Visual Inspection of Therapeutic Protein Drug Products
Просмотров 5622 месяца назад
A drug product is a final dosage form of a drug in its designated container. When manufacturing a drug product, multiple tests are performed to ensure that regulatory and quality standards are maintained at each stage of the process. One example of a drug product quality test is the visual inspection of filled containers during a process called the fill/finish process. This animation explains w...
