The mRNA sequence produced by the elongation process contains two areas – exons, strips which code for a protein and introns which are non-coding strips. The intron strips must be removed from the mRNA sequence while attaching the split exons to form the mRNA strand for translation to occur....
11、enylation;The sequence AAUAAA is necessary for cleavage to generate a 3 end for polyadenylation.CABD编码区 A、B、C、D非编码区真核生物结构基因,由若干个编码区和非编码区互相间隔开但又连续镶嵌而成,去除非编码区再连接后,可翻译出由连续氨基酸组成的完整蛋白质,这些基因称为断裂基因3、RNA的剪接(RNA...
DNA is a what that encodes protein sequences? What are the structures of RNA and DNA and how might one be used to create the other? During the process of protein synthesis each tRNA carries one what? Which amino acid is coded by the mRNA sequence CAU?
如果让核糖体直接对基因组 DNA 进行操作，那么你要让核糖体在通常远长于 mRNA 的基因组 DNA 上准确定...

转录是基因表达为蛋白质的第一阶段。在转录中,mRNA(信使 RNA)中间体从 DNA 分子的一条链转录而来。 The RNA is calledmessenger RNAbecause it carries the "message," or genetic information, from the DNA to the ribosomes, where the infor...

DNA(脱氧核糖核酸)到蛋白质的转换是生物学中的一个基本过程,这个过程被称为翻译。在翻译过程中,DNA序列首先被转录成mRNA(信使核糖核酸),然后mRNA上的密码子(每三个核苷酸一组)被翻译成相应的氨基酸,最终形成蛋白质。 以下是一个简化的Python函数,用于模拟DNA序列到蛋白质序列的转换。这个函数假设输入的DNA序列是有效...
• The mRNA that gets sequenced is sent out of the nucleus to help make protein Genetic Code • Sequence of Nitrogenous Bases codes for a specific Amino Acid that is connected to other amino acids to make a Protein • Codon = the nitrogenous bases of 3 adjacent nucleotides in mR...
Repetitive DNA sequences playing critical roles in driving evolution, inducing variation, and regulating gene expression. In this review, we summarized the definition, arrangement, and structural characteristics of repeats. Besides, we introduced diverse biological functions of repeats and reviewed existing...
