Then again, an arising field called single-cell RNA sequencing is utilized for transcriptome profiling at the individual cell level. The standard conventions for both these kinds of investigations remember the handling of sequencing libraries and result for the age of tally frameworks. An impediment to these investigations and the obtaining of significant outcomes is that both require programming skill.
Although RNA-Seq is still a technology under active development, it offers several key advantages over existing technologies. First, unlike hybridization-based approaches, RNA-Seq is not limited to detecting transcripts that correspond to existing genomic sequences. For example, 454-based RNA-Seq has been used to sequence the transcriptome of the Glanville fritillary butterfly. This makes RNA-Seq particularly attractive for non-model organisms with genomic sequences that are yet to be determined.

RNA-Seq can reveal the precise location of transcription boundaries to a single-base resolution. Furthermore, 30-bp short reads from RNA-Seq give information about how two exons are connected, whereas longer reads or pair-end short reads should reveal connectivity between multiple exons. These factors make RNA-Seq useful for studying complex transcriptomes. In addition, RNA-Seq can also reveal sequence variations (for example, SNPs).
