mRNA

abbreviation for messenger RNA.

messenger RNA

An RNA (ribonucleic acid) molecule which has coding regions and translation signals derived from a gene, carries the reverse template message from DNA, and is required for protein synthesis. mRNA is a nucleic acid intermediate that specifies the amino acid sequence of a polypeptide during translation. Under most circumstances, and in accordance with the so-called central dogma of biology, the message flows from DNA to RNA, which is then translated into protein. DNA is wrapped around proteins (histones in chromatin); the DNA then unwinds, allowing transcription by one of the three RNA polymerases, forming a primary (nuclear) RNA transcript that is then processed to remove the intervening RNA sequences (introns), yielding a mature mRNA molecule. The mature mRNA then passes through nuclear pores into the cytoplasm, where translation into proteins occurs. When a particular mRNA is no longer needed, it is degraded by ribonucleases.

mRNA

a unique set of tRNAs, mRNAs, rRNAs, transcribed from mitochondrial DNA by a mitochondrial-specific RNA polymerase, which account for about 4% of the total cell RNA which is transcribed.

Previously we introduced a unique system of leukocyte mRNA analysis from whole blood, in which leukocytes were trapped on a 96-well filter plate and leukocyte lysate was transferred to a 96-well oligo(dT)-immobilized microplate for direct poly[(A).
Extracting enough mRNA to conduct the studies was a difficult task because metabolic rates of microorganisms in the deep biosphere are very low and mRNA is about only 4 to 10 percent of the total RNA they make, Orsi said.
In addition to skipping and inclusion of variable exons and usage of alternative splice sites,3 intron retention is a third example of alternative splicing, whereby an intron sequence is retained or skipped in the mature mRNA transcript.
The main objectives of this study were to develop a qualitative reverse transcription PCR (RT-PCR) detecting spliced mRNA from HBoV1 and to clarify whether HBoV1 mRNA detection may correlate better than DNA detection with RTIs in children.
