MI 3.1.4 & 3.1.5 Microarrays

Front

What is transcribed from DNA to produce a protein and is a good indication of whether or not a particular gene is expressed?

Back

mRNA

Front

What happens after the DNA from the sample is applied to the DNA microarray?

Back

the cDNA will hybridize with the single stranded DNA molecules on the microarray

Front

In the microarray, what does the RED color indicate?

Back

these genes are expressed or turned on in cancer

Front

What does the GREEN color indicate in DNA microarray?

Back

these genes are not expressed in cancer

Front

What does the YELLOW color indicate in DNA microarray?

Back

this gene is expressed in both cancer and healthy cells

Front

What does BLACK indicate in dna microarray?

Back

no gene expression

Front

Which genes are expressed in both normal and in cancerous cells? Options: Genes marked by red spots only, Genes marked by red and green spots, Genes marked by black and yellow spots, Genes marked by yellow spots only

Back

Genes marked by yellow spots only

Front

Which unknown gene sequences might belong to cancer-suppressor genes? Options: Genes marked by red spots, Genes marked by green spots, Genes marked by black spots, Genes marked by yellow spots

Back

Genes marked by green spots

Front

When comparing healthy and cancerous lung cells on a microarray, what color would you expect the dot that represents the gene for producing melanin (pigment for skin color)?

Back
