Thus an important part of basic and applied genomics is to identify and localize these genes in a process known as transcript mapping. When genes are expressed, their sequences are first converted into messenger RNA transcripts, which can be isolated in the form of complementary DNAs (cDNAs).

Transcript quantification determines the steady state levels of alternative transcripts within a sample, enabling the detection of differences in the expression of alternative transcripts under different conditions.

Find the approximate origin of a sequence. Alignment: Find the exact difference between two sequences.

Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.

Transcript expression level, refers to how abundant a transcript is, i.e. if a certain mRNA (a transcript) exist in many or few copies (expression level). DE analysis is the analysis of Differentially Expressed genes.

It works by blasting assembled contigs against a non-redundant protein database (at NCBI), then annotating them based on sequence similarity. GOanna is another GO annotation program specific for animal and agricultural plant gene products that works in a similar fashion.

Transcriptomics has been defined by repeated technological innovations that transform the field. There are two key contemporary techniques in the field: microarrays, which quantify a set of predetermined sequences, and RNA sequencing (RNA-Seq), which uses high-throughput sequencing to capture all sequences.
