What is pre-mrna?
Ribonucleic acid (MRNA) is used in protein synthesis in animals and plants. MRNA precursor, or pre-mrna, is the first transcript from the gene that encodes proteins. Sometimes it is called immature MRNA, it is basically a MRNA that still has to connect. PRE-MRNA is an important part of the process that follows common macromolecular DNA, which contains genetic information for living organisms.
Within the ongoing process of ribonucleic acid production (RNA) there is a pre-mrna for a short time. It is a phase between the gene that has been rewritten to MRNA and the protein to which it will be translated. It removes unnecessary parts by lining to make MRNA. PRE-MRRNA contains both intrines and exons. Introns are cuts that do not contain the information necessary for protein coding. Introns must be removed with a cutting mare to create a functional molecule containing only exons. Exony contains information that will then be used in the production of proteins.
enzymes perform a kind of cut and insertedand. They create a spice -sofa made of ribonucleoproteins and other proteins. The plicesom cuts the introns from the sequence in front of the MRNA and then connects the remaining exons so that there are no gaps in the code. Introns tend to be much longer than exony, so the spring will be significantly longer than the RNA chain that will result in a haircut.
This process occurs in the cell nucleus and must be very accurate. Any disturbance of the processing process can cause or modify the disease in the human body. It is known that viruses such as influenza virus interferes or even inhibit a haircut in front of MRNA, which inhibits the formation of the necessary proteins. Binding proteins are also a factor in pre-mrna control and regulation. They can cause significant changes that then activate other processes.
genes produce pre-mrna, which have the same components as MRNA such as phosphates and ribos sugar. It also contains uracil nucleobases, adenIn, guanine and cytosine. The successful translation of the pre-mrna to RNA allows you to move outside the core where it is translated into a protein. RNA is a single -threaded molecule that helps to create a two -thirds DNA.
Molecular biologists have examined the ways of manipulating pre-mrna to affect gene expression and cloning processes. The altitude occurs naturally in cells. It can also be controlled in the laboratory.
