Using Microarrays to Detect Cancers – Genomics
About the Lecture
The lecture Using Microarrays to Detect Cancers – Genomics by Georgina Cornwall, PhD is from the course Genomics.
Included Quiz Questions
Which of the following is true regarding microarrays?
- They depend on mRNA extraction from normal and cancerous tissues.
- They can be used to determine if any cell in the body contains a cancer-causing gene mutation.
- They involve reverse transcription of DNA.
- They can only identify genes that are expressed in cancer cells.
- They require the patient to be anesthetized.
Using microarray technology, a scientist labeled a cancer-tissue sample with a red fluorescent dye and the reference sample with a green fluorescent dye. What will the colors indicate when scanning the microarray chip?
- Green spots and red spots indicate the expression of healthy and cancer-related genes, respectively. Yellow spots indicate gene expression in both samples.
- Red spots and green spots indicate the expression of healthy and cancer-related genes, respectively. Yellow spots indicate gene expression in both samples.
- Green spots and red spots indicate the expression of healthy and cancer-related genes, respectively. Purple spots indicate gene expression in both samples.
- Yellow spots and red spots indicate the expression of healthy and cancer-related genes, respectively. Green spots indicate gene expression in both samples.
- Green spots and yellow spots indicate the expression of healthy and cancer-related genes, respectively. Red spots indicate gene expression in both samples.
