How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA.
Scientists have discovered that tRNAs can determine how long mRNAs exist in a cell, causing some messages to be stabilized ...
撰文丨王聪编辑丨王多鱼排版丨水成文众所周知，根据中心法则，DNA转录为mRNA，mRNA再翻译为蛋白质，mRNA的降解速率是每个基因产生的蛋白质的数量的主要决定因素，而这又会影响细胞功能。例如，对于mRNA疫苗，mRNA存在更长时间会产生更多蛋白质，从而更好地激活免疫系统以抵抗感染；而对于CRISPR-Cas9基因编辑，产生Cas9蛋白 ...

Study reveals RNA's unknown role in DNA damage repairRNA molecules are best known as protein production messengers. They carry genetic instructions from DNA to ribosomes—the ...
In fact, this flow of information from DNA to RNA and finally to ... ribosome shifts to the next codon on the mRNA. At this point, the corresponding tRNA binds to this codon and, for a short ...
RNA polymerase enzymes read the DNA sequence and synthesize messenger RNA (mRNA) molecules, which carry the genetic ... which fold into functional proteins. Transfer RNA (tRNA) molecules play a ...
Messenger RNA (mRNA) carries the genetic information from DNA to the ribosomes, where proteins are synthesized. Transfer RNA (tRNA) and ribosomal RNA (rRNA) are involved in the translation of mRNA ...
When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...
