How to isolate mRNA
Minou Nowrousian
Background: mRNAs (messenger RNAs) comprise only a small percentage of all RNA species in a eukaryotic cell, in Neurospora usually ~ 1-6 % (Lucas et al., 1977; Sturani et al., 1979). For some applications like preparation of a cDNA library, target preparation for microarray hybridizations or Northern blot analysis of weakly expressed genes, enriched mRNA preparations are preferable to total RNA. Enrichment of eukaryotic mRNAs derived from nuclear encoded genes is done by virtue of their poly(A) tail which in most cases is 30-200 nt long. mRNA or poly(A)-RNA preparation consists of three steps: (1) hybridization of poly(A)-containing RNAs to oligo-dT molecules connected to a carrier, (2) washing off nucleic acids which do not bind to oligo-dT
The three types of RNA include; messenger RNA (mRNA), RNA polymerase, and transfer RNA (tRNA).
Messenger RNA (mRNA) Ribosomal RNA ( rRNA ) Transfer RNA ( tRNA )
RNA polymerase is the enzyme responsible for synthesizing RNA strands during transcription in a cell. It reads the DNA template strand and adds complementary RNA nucleotides to form an RNA strand.
The four types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), ribosomal RNA (rRNA), and small nuclear RNA (snRNA). Each type plays a specific role in the process of protein synthesis within cells.
RNA contains nucleotides, which are the building blocks of RNA molecules. Nucleotides are connected in a specific sequence to form the RNA molecule.
RNA polymerase is an enzyme that makes a RNA copy from an RNA template.
The three types of RNA are: mRNA (messanger RNA), rRNA (ribosomal RNA), and tRNA (transfer RNA).
