DNA：Definition DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce. These instructions are found inside every cell, and are passed down from parents to their children.DNA：Structure DNA is made up of molecules called nucleotides. Each nucl...

The double helix structure of a DNA molecule was later discovered through the 60 (experiment) dat a by James Watson and Francis Crick. 61 (eventual), it was proved that DNA is responsible for storing genetic information. 相关知识点:
5.The first tRNA detached from the its amino acids and he ribosome moves along the mRNA molecule,and a new tRNA with the amino acids will bind with the next codon. 6.The polypeptide is formed gradually until the ribosome reach the stop codon,then the formation of the polypeptide is complet...

Figure 1: A single nucleotide contains a nitrogenous base (red), a deoxyribose sugar molecule (gray), and a phosphate group attached to the 5' side of the sugar (indicated by light gray). Opposite to the 5' side of the sugar molecule is the 3' side (dark gray), which has a free ...
Your genetic information is strung into a long and twisted molecule, the DNA double helix, that has over three billion letters, beginning to end. 你的遗传信息串成了一段长而扭曲的分子,即DNA双螺旋结构,它有着超过三十亿个碱基,从开始到结束。 But the lines that carry meaningful information are us...
Here, we report the construction from DNA of a covalently closed cube-like molecular complex containing twelve equal-length double-helical edges arranged about eight vertices. Each of the six 'faces' of the object is a single-stranded cyclic molecule, doubly catenated to four neighbouring strands,...
Is a molecule (carbohydrates,fat, protein,DNA/RNA) larger in size or a molecular complex (dimers, trimers, tetramers)? Answer and Explanation: A molecular complex is made up of multiple molecules. So assuming you are comparison a single type of mo...
DNA was shown to be responsible for genetic inheritance in 1944. Then, in 1953, its structure was revealed using X-rays. And DNA turns out to be a stunningly elegant molecule. What you’re looking at is the original DNA model currently ...
