DNA:DNA means deoxyribonucleic acid. It is a hereditary material which is present in all living organisms. DNA contains all the hereditary information. It forms a double helix structure and nucleotides are the basic part of DNA. RNA is also known as ribonucleic acid. It is a polymer...
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...
The discovery of the DNA structure allowed scientists to propose two important functions of DNA. First of all, they were able to hypothesize that there are two strands of DNA in order to have a simple mechanism of copying the genetic material in the molecule. This is achieved by the ...

(a)Compare between DNA replication and transcription.Similarities1. Both involve unwinding of the double helix DNA;2.Both involve breaking of the weak hydrogen bonds between complementarbases;3.Both involve formation of phosphodiester bonds between neighbouring nucleotides;4.Both involve aligning free nucl...
Step 2: Functions of the Nucleus- The nucleus is responsible for storing genetic information in the form of DNA. This genetic material is crucial for the inheritance of traits and the functioning of the organism.- It controls the activities of the cell by regulating gene expression. This means...
DNA (eDNA) signatures and information useful to analyse the honey bee hologenome complexity. In this study, we tested a deep shotgun sequencing approach of honey DNA coupled with a specifically adapted bioinformatic pipeline. This methodology was applied to a few honey samples pointing out DNA ...

The community of microorganisms inhabiting a specific environment, such as the human gut - including bacteria, fungi, archaea, viruses, protozoa, and others - is known as the microbiota. A holobiont, in turn, refers to an integrated ecological unit where microbial communities function and interact...
Describe the structure of DNA, nucleotides and N-bases. Describe the basic structure of DNA. Discuss why DNA is often called a "protein recipe". Explain the relationship between genetic characteristics and DNA structure. Summarize how DNA and RNA differ in structure and function. ...
