Genes produce pre-mRNA, which has the same components as mRNA, such as phosphates and ribose sugar. It also contains the nucleobasesuracil, adenine,guanineandcytosine. Successful translation of pre-mRNA into RNA enables RNA to move outside of the nucleus, where it is translated into protein. ...
与原核生物明显不同的是,真核RNA聚合酶在转录过程中与mRNA加工酶结合,因此,真核生物的mRNA加工可以在转录开始后快速进行。短寿命的未加工或部分加工的转录产品称为前体mRNA或pre-mRNA;一旦加工完全,它被称为成熟mRNA。 真核pre-mRNA加工 mRNA的加工在真核生物、细菌和古细菌中差异很大。实质上,非真核mRNA在转录时...
What is added to pre-mRNA in order to protect it from degradation? What is a complementary mRNA codon? RNA splicing removes ___ from the mRNA while keeping the ___. What does a mutation in the DNA do to the mRNA? Other than mRNA...

IDO1, a monomeric heme-containing enzyme, is one of the three enzymes that catalyze the first and rate-limiting step in the kynurenine pathway (KP), leading to the degradation of the essential amino acid tryptophan (TRP) and generation of kynurenine (KYN) and other downstream metabolites, in...
During translation, a three-nucleotide sequence of mRNA called a codon specifies whichshould be linked up next. It is important to maintain the integrity of codons so thecan link the correct amino acids together and form the correct protein. When a frameshift mutation occurs, there is an error...

"pre mRNA". This is the RNA that is directly made during transcription. After the pre mRNA is transcribed, it will be finished off, with the addition of a cap and tail (which help protect the mRNA), and through the process of splicing. Once this is completed, it is called mature ...
Genes are units of DNA that serve as discrete pieces of information from the cell, which information can be used to create a certain end product, usually in the form of a protein, mRNA, or other distinct e...
