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...

1. DNA转录(Transcription): 起始点: 转录过程始于DNA上的一个特定位置,称为起始点。 RNA聚合酶: 在转录开始时,RNA聚合酶结合到DNA上,并开始沿DNA模板链合成一条新的RNA链。 模板链与新合成RNA: RNA聚合酶按照DNA模板链的顺序,将RNA中的腺嘌呤(A)、胞嘧啶(C)、鸟嘌呤(G)、尿嘧啶(T)替换为相应的腺苷酸...

replication- DNA is used as a template to make more DNA, resulting in 2 DNA molecules each with one old and one new strand. In transcription DNA is used as a template to make RNA (mRNA). In translation the sequence of mRNA is decoded into a protein...
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 ...
genes that code for ribosomal RNA, transfer RNA, or other small RNAs, in which the transcription product is used directly; and regulatory sites that are not transcribed but serve as recognition sequences for proteins involved in deoxyribonucleic acid ( DNA) replication, transcription, and repair. ...
