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
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 is a DNA microarray?
In a DNA microarray, thousands of DNA fragments are spotted onto a glass slide. Usually, it is a fragment of each gene (or cDNA) that is spotted onto these glass slides. Each of these fragments will be used for a hybridization reaction with mRNA that is collected from tissue samples. To determine the expression of these tissues, mRNA is collected and turned into cDNA. Fluorescent labeled nucleotides are added to the sample so that they will be detectable under a colored laser. Two samples are usually compared to each other. The labeled cDNAs are allowed to hybridize with the genomic fragments that were spotted onto the glass slides. The cDNAs from each sample will be able to simultaneously hybridize with the target sequences.
How can DNA microarrays compare gene expression in different cells?
DNA microarrays can compare gene expression in different cells by isolating mRNA from each cell type, converting it to cDNA, and then hybridizing it to the microarray. The microarray contains probes for thousands of genes, allowing for simultaneous measurement of gene expression levels across the samples. By comparing the intensity of hybridization signals for each gene, researchers can identify genes that are differentially expressed between the cell types.
What is the purpose of the cDNA synthesis?
The purpose of cDNA synthesis is to synthesize a copy of DNA from mRNA. This means that it is involved in the duplication of DNA that occurs when a cell divides. As a result, without cDNA synthesis, life would not exist as cells would not be able to divide.

Is cDNA complementary to mRNA?
Yes, cDNA is complementary to mRNA.
What is the full form of cdna?
CDNA = Complimentary Deoxyribose Nucleic Acid

How can I create cDNA in the laboratory?
To create cDNA in the laboratory, you can follow these steps: Extract RNA from the cells or tissue of interest. Use reverse transcriptase enzyme to convert RNA into cDNA. Purify and amplify the cDNA using PCR (polymerase chain reaction). Verify the cDNA sequence through sequencing techniques.
CDNA is copied from?
mRNA
What is a cDNA library used for?
A cDNA library is used for complementary DNA. These DNA are collected as host cells, which can be found in the nucleus. Currently, cDNA libraries are lacking in the enhancer, intron, and several other categories.
The function of cdna?
hi In vitro we must converted the RNA to cDNA to diagnosis viral RNA in PCR. In vivo RNa viral infected the cell RNA converted to cDNA IN SIDE THE CELL BY REVERSE TRANSCRIPTASE therfore cDNA insertion in the DNA of cell infected thank you hi In vitro we must converted the RNA to cDNA to diagnosis viral RNA in PCR.

What is the advantage of using cDNA library in molecular genetics?
The main advantage of cDNA library is that it contains only the coding region of a genome.
Does cDNA have a promoter region?
Yes, cDNA does not have a promoter region because it is synthesized from mRNA and lacks the regulatory elements found in genomic DNA.
