What are three structural differences between DNA and RNA? How are DNA and RNA structurally similar? How are DNA and messenger RNA alike? How does the sugar in a DNA nucleotide differ from that of an RNA nucleotide? How can RNA be distinguished from DNA?
1. DNA含有脱氧核糖,RNA含有核糖;2. DNA含有胸腺嘧啶(T),RNA含有尿嘧啶(U);3. RNA的核糖在2'位置有羟基,DNA的脱氧核糖2'位置为氢原子。 1. **五碳糖差异**:DNA的糖基为脱氧核糖(缺少2'羟基),RNA为核糖(2'羟基存在)。这是两者结构的关键化学标志。2. **碱基差异**:DNA使用胸腺嘧啶与腺嘌呤配对,而...
How does the structure of DNA differ from that of RNA? What is the role of RNA and how does it differ from DNA? What are the differences between DNA and RNA? What are the differences of DNA and RNA? How do RNA and DNA viruses differ?
1) Compare the differences between DNA and RNA, structurally and functionally. Can you explain why DNA is more favorable as a genetic material? Answer: The differences between DNA and RNA in the structure (1) DNA contains deoxyribose in contrast to the ribose in RNA. (2) DNA has the thymi...
RNA 以 5' -> 3' 方向合成(从生长的 RNA 转录本可以看出)。转录有一些校对机制,但没有 DNA 复制那么多。有时会出现编码错误。 Differences in Transcription 转录差异 【4】There are significant differences in the process of transcription in...
DNA vs RNA: The Key Differences What is the difference between DNA and RNA, or the ribose vs deoxyribose nucleic acids? This DNA vs RNA chart allows you to easily see each of the important ways that DNA and RNA differ from each other. ...
2.6.U2 DNA differs from RNA in the number of strands present, the base composition and the type of pentose. 跟DNA比起来,RNA分子是比较短的片段,一般从几倍到上千个核苷酸长。它是单链结构,骨架中的五碳糖是核糖,碱基则是GACU,U替代了DNA中的T。RNA的种类有三种,mRNA(messenger RNA)存在于细胞核和...
DNA and RNA are nucleic acids. Both are polymers made from nucleotides. Also, both their nucleotides have a similar structure with slight differences. Moreover, the nucleotides of each nucleic acid have two different purine bases and pyrimidine bases. ...
RNA. DNA viruses show accurate replications while RNA viruses show error-prone replication. Apart from that, DNA viruses are stable and show a lower mutation rate while RNA viruses are unstable and show a higher rate of mutation. This is the summary of the differences between DNA and RNA ...
DNA and RNA both carry genetic information, but there are quite a few differences between them. For example, DNA's double-stranded structure provides stability and protection for genetic information, while RNA's single-stranded nature makes it more chemically reactive and prone to being broken down...
