A microarray is a multiplex lab-on-a-chip. It is a 2D array on a solid substrate (usually a glass slide or silicon thin-film cell) that assays large amounts of biological material using high-throughput screening methods

What is the meaning of CDNA microarray?
A cDNA microarray is a hybrid of a DNA microarray, which is a collection of a number of minute DNA dots. These are mostly used in the field of genetic testing.
What is extracted from cells for DNA microarray technology?
mRNA is extracted from cells for DNA microarray. the mRNA is then converted in the lab to cDNA this cDNA is allowed to interact with the probes on the microarray chip
How does the technology of microarray work?
it works by chips
What is the purpose of DNA microarray analysis?
Otherwise known as "microarray chips," DNA microarray are used to determined the genetic makeup of a given tissue sample. By shining various bands of light on these chips, the gene(s) in the tissue are expressed in the form of a particular color.
What has the author DO STEKEL written?
DO STEKEL has written: 'MICROARRAY BIOINFORMATICS'
How do scientists use microarray analysis?
Microarray analysis involves breaking open a cell, isolating its genetic contents, identifying all the genes that are turned on in that particular cell and generating a list of those genes.
What is DNA microarray data analysis used for?
DNA microarray analysis is a technique used to match up two strands of DNA. It is used in paternity tests and in criminal investigations in which a perpetrator's DNA was found at the crime scene.
3 Why should you normalize the micro array data?
Microarray data is usually applied for the comparison of gene expression profiles under different conditions. But we have to make sure what we are comparing is really comparable. So, to bring the data under common frame normalization is done. In technical terms, normalization of microarray data removes both random and systematic biases.

What are the pros and cons of integrating DNA microarray or chip technology into the forensic DNA laboratory?
no profit to answer
What technique could tell you how gene expression differs between individuals with and without cystic fibrosis?
DNA Microarray
What are the steps of DNA microarray assays?
Step 1: Isolate the mRNA. Step 2: Make cDNA by reverse transcription using fluorescent labeled nucleotides. Step 3: Apply the cDNA mixture to a microarray with a different gene in each spot. Step 4: Rinse off excess DNA; scan for fluorescence.
What technique has been applied to studying the timing of replication initiation in different regions of the genome?
The time of replication initiation can be measured through MICROARRAY ANALYSIS because it uses flourecent labelled nucleotide.
