产生mRNA: 结果产生的RNA称为信使RNA(mRNA),它携带着基因的信息离开细胞核,进入细胞质。 2. DNA翻译(Translation): mRNA到tRNA: 在细胞质中,mRNA与适配体RNA(tRNA)结合。tRNA上的氨基酸与mRNA上的密码子相对应。 氨基酸连接: tRNA将其携带的氨基酸与相邻的氨基酸连接,形成多肽链。 蛋白质合成: 通过不断重复这一...
Once the transcription process is done, the translation process starts in the cytoplasm of the cell to create protein. The complex process of transcription involves several proteins, enzymes and lysine among others to carry out every step during the attachment of polymerase, detecting the specific si...
转录过程(蛋白质合成第一步)Transcription 2.7.U4 Transcription is the synthesis of mRNA copied from the DNA base sequences by RNA polymerase. 2.7.U6 The amino acid sequence of polypeptides is determined by mRNA according to the genetic code 2.7.U7 Codons of three bases on mRNA correspond to one...
In this lesson, you'll learn about the roles of DNA, mRNA, tRNA, and ribosomes in protein formation. We'll provide an overview of the processes of transcription and translation in protein formation. The Journey from Gene to Protein It's commonly known that DNA is 'the building block of...

▲【5】In prokaryotes (bacteria), transcription occurs in the cytoplasm. Translation of the mRNA into proteins also occurs in the cytoplasm. In eukaryotes, transcription occurs in the cell's nucleus. mRNA then moves to the cytoplasm ...
How do transcription and translation result in the expression of genes? Explain the difference between DNA replication and RNA transcription. Explain the role of tRNA in protein synthesis. Include a description of how it interacts with mRNA and the ribosome. ...
While transcription and translation are relatively separate processes, they are part of one of the most important and central ideas of biology: using genetic information found in DNA to create proteins. This is called the central dogma of biology....
Genetic information in an organism is expressed in three classes of genes—structural (protein-coding) genes that are transcribed into messenger ribonucleic acid (mRNA) and translated into polypeptides; genes that code for ribosomal RNA, transfer RNA, or other small RNAs, in which the transcription...
DNA Transcription & Translation *How do genes work? We’ve seen how DNA is replicated, but still haven’t learned exactly how genes work! The first step in understanding how genes work is to know how to “decode” the DNA. Decoding DNA The decoder: RNA (Ribonucleic acid) Long stranded ...
