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).

Summary of RNA-Seq. Within the organism, genes are transcribed and (in an eukaryotic organism) spliced to produce mature mRNA transcripts (red).This data can be used to annotate where expressed genes are, their relative expression levels, and any alternative splice variants.

A genetic map is a type of chromosome map that shows the relative locations of genes and other important features. The map is based on the idea of linkage, which means that the closer two genes are to each other on the chromosome, the greater the probability that they will be inherited together.

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.

Picard can be used for quality control in mapping. Either with a reference or de novo assembly, the complete reconstruction of transcriptomes using short reads is challenging. For example, short reads can sometimes align equally well to multiple locations (multi-mapped reads or multi-reads).

Transcription is a process of making an RNA strand from a DNA template, and the RNA molecule that is made is called transcript.RNA takes that information into the cytoplasm, where the cell uses it to construct specific proteins, RNA synthesis is transcription; protein synthesis is translation.
