Which tools are used for microarray analysis?
Only three tools can handle all types of classical microarrays, namely ArrayExpress and NCBI GEO for storage and Bioconductor for analysis.
What is the application of bioinformatics in analyzing the microarray data?
Bioinformatics analysis plays an important part of processing the information embedded in large-scale expression profiling studies and for laying the foundation for biological interpretation. Over the past years, numerous tools have emerged for microarray data analysis.
Which database have microarray chip data in bioinformatics?
A new schema is proposed to store microarray data by using array data type in an object-relational database management system – PostgreSQL. The implemented database can store all the microarray data from the same chip in an array data structure.
What is microarray data mining?
A microarray is a laboratory tool used to detect the expression of thousands of genes at the same time. DNA microarrays are microscope slides that are printed with thousands of tiny spots in defined positions, with each spot containing a known DNA sequence or gene.
How is microarray analysis used today?
Today, DNA microarrays are used in clinical diagnostic tests for some diseases. Microarrays can also be used to study the extent to which certain genes are turned on or off in cells and tissues. In this case, instead of isolating DNA from the samples, RNA (which is a transcript of the DNA) is isolated and measured.
Why is DNA microarray an important tool?
DNA microarray is an effective tool in transcriptomics that helps us in studying and analyzing the mRNA expression of almost every gene present in an organism. With the availability of whole-genome sequencing of microorganisms, it has now become possible to identify the genes with potential for bioremediation.
What is DNA microarray analysis?
The DNA microarray is a tool used to determine whether the DNA from a particular individual contains a mutation in genes.
