MicroRNAs are small molecules that do not themselves encode proteins but bind to messenger RNAs that to do this. They act as gates for messenger RNAs and prevent their translation into proteins, but how they produce this effect and at what stage of protein synthesis they intervene has long been a mystery. WebAlthough miRNA does not encode a protein, it degrades or inhibits the translation by interacting with the 3′ untranslated regions of specific target mRNA at the post-transcriptional level and regulates the expression of the target gene. 6 It is further involved in tumor development, including oncobiology, invasion, metastasis, and ... how much is trackmania on steam
