What is the role of Messenger RNA?
Messenger ribonucleic acid (MRNA) is a molecule of ribonucleic acid (RNA), which encodes the correct sequence of amino acids in protein. This is a copy of the DNA sequence, which is located in the genetic material in the cell nucleus. After creating Messenger RNA, it is transported to the protein construction in the body of the cell, called ribosome. Ribosom reads Messenger RNA and translates it into protein. It is basically a long chain of sub -components called nucleotides. A specific sequence of nucleotides encodes the information that Messenger RNA carries from one place to another.
The main plan for the body is contained in DNA. DNA is long -term storage for all different sequences of amino acids that are needed to create an organism. These information sequences are popularly called genes.
Ribosomes have the ability to construct proteins, but not the information needed to create a particular protein. In this way they are like a computer without a program. If protein is needed, it must be copied and deliveredSt DNA into the ribosome. Messenger RNA is a copy and works as a software needed to create a protein. Inside the ribosome, the soup of amino acid ingredients that will be connected together to form a specific protein.
Human Messenger takes from one minute to a few days. It is formed during a process called transcription and lasts until the protein is designed. It then disintegrates in a process called degradation. A number of other processes may occur between transcription and degradation.
Active RNA begins with a closure, which is tied to the beginning of the mrna while the transcription begins. Sometimes there is a copied DNA that has sections that nentain any useful information. Before using MRNA, these sequences are removed in a process called haircut.
In some cases, Messenger RNA is "modified" by inserting a marker that will end the design before the end of the sequence. Edit creates a shortened version of protrumein. At the end of his life, the cap is removed from the mrna, after which the cell no longer uses it.
Copying genetic information requires several other types of RNA. The first is ribosomal RNA, which decodes Messenger RNA into individual amino acids. This occurs at the synthesis in the ribosome. The second type is the transfer RNA, which combines the necessary amino acids in a sequence of dictated MRNA.
