Transcriptomics

Definition

Transcriptomics is the study of the complete set of RNA transcripts produced by the genome under specific circumstances or in a specific cell using high-throughput methods. It helps understand gene expression and regulation.

5 Must Know Facts For Your Next Test

1. Transcriptomics involves RNA sequencing (RNA-Seq) to analyze the transcriptome.
2. It helps identify differentially expressed genes under various conditions.
3. Microarrays can also be used in transcriptomics to measure gene expression levels.
4. Transcriptomic data can provide insights into functional elements of the genome.
5. Applications include understanding disease mechanisms, drug development, and microbial response to environmental changes.
