In eukaryotes, there are three post-transcriptional events that must occur in order to form mature messenger RNA:. Post-Transcriptional Modifications. Alternative Splicing.

Unlike microRNAs, which have been extensively studied, lncRNAs present in follicular fluid have never been sequenced and the biological associations of lncRNAs in healthy follicles and follicles in women who develop PCOS remain largely unknown. A total of 18 subjects 8 controls and 10 PCOS patients were recruited to participate in this study. Recruitment took place from May to September

This mature mRNA is then translated into a polymer of amino acids: a protein, as summarized in the central dogma of molecular biology. As in DNA, mRNA genetic information is in the sequence of nucleotideswhich are arranged into codons consisting of three base pairs each. Each codon encodes for a specific amino acidexcept the stop codonswhich terminate protein synthesis.

RNA is a critical component of every single living cell in the universe. Without it, life as we know it could not exist. There are three types of RNA, each with a unique function. RNA, or ribonucleic acid, is a linear polymer of adenine, thymine, cytosine, and uracil that is created in the cell by a process called transcription, and it differs from DNA in several ways.

The newly made RNA, also known as the primary transcript the product of transcription is known as a transcript is further processed before it is functional. Both prokaryotes and eukaryotes process their ribosomal and transfer RNAs. The major difference in RNA processing, however, between prokaryotes and eukaryotes, is in the processing of messenger RNAs.

Genetic information of an organism is stored in the genes, the functional subunits of the genome, arranged in the strands of the DNA double helix in the nucleus. However, in eukaryotes, before the mRNA can be translated into proteins, non-coding portions of the sequence, called introns, must be removed and protein-coding parts, called exons, joined by RNA splicing to produce a mature mRNA. RNA splicing was first discovered in s in viruses and subsequently in eukaryotes.

Appropriate expression of most eukaryotic genes requires the removal of introns from their pre—messenger RNAs pre-mRNAsa process catalyzed by the spliceosome. In higher eukaryotes a large family of auxiliary factors known as SR proteins can improve the splicing efficiency of transcripts containing suboptimal splice sites by interacting with distinct sequences present in those pre-mRNAs. The yeast Saccharomyces cerevisiae lacks functional equivalents of most of these factors; thus, it has been unclear whether the spliceosome could effectively distinguish among transcripts.

For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell divisionare all proteins.
