It contains the genetic information of the organism. DNA, the abbreviation for Deoxyribonucleic Acid, consists of two antiparallel chains (double helix) consisting of sugar, a phosphate-unit and 4 different bases. The two chains are held together by hydrogen bonds between base pairs, while the ...
The explanation of DNA conversion into RNA and finally RNA into proteins is called central dogma. 将DNA转化为RNA,最后将RNA转化为蛋白质的解释称为中心法则。 DNA contains hereditary information that is passed on to you from your parents. DNA包含了从父母那里获得的遗传信息。 If you and your father...
DNA的英文全称是Deoxyribonucleic acid。即脱氧核糖核酸，是分子结构复杂的有机化合物。作为染色体的一个成分而存在于细胞核内。功能为储藏遗传信息。DNA 分子巨大，由核苷酸组成。核苷酸的含氮碱基为腺嘌呤、鸟嘌呤、胞嘧啶及胸腺嘧啶；戊糖为脱氧核糖。1953 年美国的沃森(James Dewey Watson)、英国的克里克...

DNA：Structure DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what ...
The bases that carry the genetic code are tucked safely in the interior of double-helical B-form DNA, protecting them from damage. This hereditary information needs to be constantly accessed in living cells, thereby necessitating DNA supercoiling. Organisms have evolved DNA supercoiling to toggle ...
As its name implies, an STR contains repeating units of a short (typically three- to four-nucleotide) DNA sequence. The number of repeats within an STR is referred to as an allele. For instance, the STR known as D7S820, found on chromosome 7, contains between 5 and 16 repeats of GATA...
There are two major classes of chemical probes of DNA structure: those that demonstrate no inherent base preference but are sensitive to DNA geometry, such as groove widths and chirality, and those that are base-specific, detecting bases in distorted regions of the helix. The former bind to DN...
